Title: Straight cut primary gears for a Sachs
Post by: john durrill on June 02, 2003, 08:57:02 AM
How many of us would be willing to buy  a set of straight cut primary gears for the 100/125 Sachs engine Pentons if we could find a supplier?
 Its a 1.2 hp gain and no loss in reliabilty

John;
I recall that you looked into this about a year ago and couldn't find a supplier. At that time it seemed like there was a good bit of interest. Depending upon the cost, I might be interested in a set.

Yes we did but i was looking for gears that were already made.
 this time we are researching someone to build them. Dosent look like we will find and NOS gears like that.
The cost will depend on how may folks would be willing to buy a set. I know i would spring for a set unless the are  very expensive.

It sounds like something that would be worth trying if its not cost prohibitive.

Ok  guys,
 I should have the fax # for an former MZ enginer today. He has done straight cuts for Martijn for 50 cc bikes and uses a Czech company to do the manufacturing. Looks like this will be a go unless they are very expensive. How many would like them if we can get a reasonable price?

John, do you contemplate that the layshaft wheel will have a needle bearing and not the bushing that is stock?  I just re-read your article on the needle bearing on a stock gear and I thought I would ask the question.

 it would have the hole for a stock bushing unless we requested them to supply a bushing with the gear sets. i would stick with the bushing. its a strong and  a proven design, but you could source any type of bearing that would fit and use it. The Bushing was used in the 175/6 and the military 180 cc Sachs.I'm not sure which article your  talking about though, could you give me a short cut to it?

If you need any info about my set of straight gears, or need them for an example, let me know.  If the new gears are not terribly expensive I would be interested in some.  I'd need to know a price before I commit though.

John, I re-read the article I was referring to, and it's not yours (Sorry!) it's from a guy named Hahn, who converted his layshaft gear from a bushing to a needle bearing.  I downloaded it from some other site.  I left the printout at home this morning.  I'll try to remember to post the URL so it can be checked out.  If the gears are going to be remade, it might be a good idea to incorporate a needle bearing upgrade.

I'll go for a set or two if it will help get it moving at a good price. Also, the URL that Glen was refering to was  http://www.mxbikes.com/tech/ I had asked Doug about this when he rebuilt my motor and he also thought it was better to stay with the bushing. Hope this helps.

Ok Folks we have  a response from the engineer.
 Leo a Vinduro member and Sachs guy ( also a German Police Officer ) is helping with the translation.
 here is the response.
Continue with vinduro:
I just phoned with Ing. Mueller. He told me that he was the leading engineer in one of the MZ plants. He is no enduro guy, but a road racer.

He is able to make copies of the straight cut gears, but not only one and not hundreds.
Minimum is 10 and max. is 20, possible also 2 x 10. He will get the original from Martijn Stehouwer (Sachs built such gears for some factory racers of SWM, maybe Martijn has original parts, but I'm not sure), after that he will make the drawings.
The bronce bearing will be changed to needle bearings (2). It is also possible to change the ratio.

Most important is the price: It will be about 250 EUR, excl. shipping.
If he has an order for min. 10 he has to pay some money to the guys that make the gears ( I think they are in Germany or Italy, not Czechia).
Ing. Mueller has no idea how to handle the payment.
The way we did it with some spares or brochures (send the money with mail) is not the best idea, because it is more than 2.500 U.S.D. for 10 sets of gears.

If there are 10 guys who want to have the gears and pay the price, we can start thinking about the money transfer.
Leo.
 Ok guys let us know who would want a set.
 I will get one set so we need 9 more to get an order together. I do know I could not buy the steel and have it heat treated for a $100 . the setup time if I had the right cutter and an indexing rotary table would be  a lot. not even counting the # of cuts it would take to make each gear.
 The price is fair for a custom made gear with factory quality and strength.
John D.

John, almost $300 is probably beyond what I had in mind.  However, my first 125 Penton race since May of '73 will be the 28th at Byron.  If after that race I'm looking to find more power, I may commit to one set.  I'll let you know then.

Thanks for all of your hard work.

We have 2 that have committed to a set. We need 8 more. I will ask that my set not have the needle bearings. I have a new bushing that I can use. Will check and make sure that the gear has the same size hole for the needle bearing as the bushing.
 We can do a money transfer from one bank to another. I have done that in the past. It's a safe way but takes some time to do.
 We just need 8 more guys to place an order.
 Let me know, those of you that expressed a desire, if you dont want them at this price.
 We should at least reply to the information.
 Dont believe its good manners to ask some one for something like this and not give a reply.

It dosent look like we can get enough together to make the min order. I sent an e-mail to an outfit here in the states to see if they would , 1 make the gears and 2 get a price from them and 3 how many would be needed for a min. order. should hear back in a day or so on that option.

Thanks for being on top of things, John.

Trying to have items remade (and the gasps we all make when we see the cost) is a reminder that we are not living in the past when it comes to paying for new stuff.  As has been said before, look at the price of the new bikes and parts and accessories.  Add to it limited demand, and this is the result.  Whether it's pipes or gears or seats or gas tanks, if we really want them, we need to mortgage the house.  I'm going to sell my modern bike so I can pay for racing and rebuilding my next project.  One's own labor is free, and used parts are around.  But these new items are hard to swallow.

John,
I was going to let all the senior men who ride their bikes at the AHRMA & vintage races who keep the Penton flag flying take first bid on the ten sets of gears. I know I probably wouldn't put them in until I got my bike all back together and see how it rides after 30 years in the garage. But I will still commit to help all the others who want to add a little zip to their mounts. I agree that $250-$300 would be about max that I could go also.

recieved a reply from Rush Gears, they advertize building most kinds of gears in a short time frame. Looks to be a large company that build one off replacement gears.
 They declined to bid on the gear project.
 Looks like im back to looking again.
 We need 6 more that would go for the $250 price to get the German MZ enginer to design and have them made.

Mark Annan, You have some straight cut primary gears, can you notice any difference at all in the performance? I've heard they can make a winning noise, is that true?

John, I picked up the yellow pages a couple of weeks ago and called a guy listed under "gear makers". He said it's easy enough to make the gears, but the ones he makes are for commercial/industrial use. He said for a motorcycle engine you would want automotive or aircraft quality, and that the teeth should be ground after heat treat. The nearest shop to do that would be in a larger city like Detroit or Chicago.
Considering all of that and that there is a few other operations in there like milling the curved slots for the pressure plate and the (3)tapped holes, along with maybe lapping out the center hole for the bearing fit, that's a whole bunch of work.
$250 dollars does'nt sound like so much now. But I am curious as to how effective these parts really are for performance. Maybe if we all go road racing on our Sixday's we could really appreciate the added edge.
Thanks again John.
Bob

I have a used set of straight gut gears.  I have not installed them yet.  I plan to do it some time in the not to distant future.  I want to get a good feel for how my bike is with the stock setup then try the straight gears.  When I do it I will report the findings.  I'm sure they will be noisier than the stock gears.  How much I don't know.  As for HP increase I would expect a small gain ( less than 10%).

Richard, Rob , Robert , Donny
 I recieved an e-mail from Martijn.
He will buy 5 gear sets to sell in Holland if we get the other 5.
 Are you guys still interested? if so we need to contact the MZ enginer and get things rolling. I can set up the Money transfer. We have Leo in Germany ( the Police Officer) and Helmut an KTM dealer and Sachs Vintage rider in Canada to help with that. Helmut was a factory Sachs Six-Day rider and gold medal winner. He is in Germany now riding vintage enduros for the next two months.
 Please let me know as soon as you can so we can get the process in motion.

Title: Straight cut primary gears for a Sachs
Post by: john durrill on July 14, 2003, 06:02:56 PM
Robert,
It should be the same price quoted plus shipping. I think the way I read Leo's response is that we put up part of the money and they start production, then give them the rest when the gears are finished. The MZ engineer has already done gear sets for Martijn for the 50 cc bikes they roadrace in the Netherlands. He does know how to design and build good gear sets and has been reliable for Martijn.
We will need to get the monies deposited where I can transfer them to whatever bank we end up dealing with. Leo or Helmut (Speedy as he is called) will help with this.
If they are done by the RR we may be able to get Leo or one of the other two riders out of Germany to bring them over and we could pick them up then. That would help with shipping charges. We just need to stay flexible and on top of it.
John D.

OK John,
I guess you'd handle the transfer, so just let me know when to send you a money order or cashiers check and for how much. I probably wouldn't put them in the motor that Doug rebuilt for me, since it was the original, but I did pick up another that I could experiment on.

John, I'd take the set that Bob/Rob W isn't going to take now. I can be reached by email or phone (510)481-0554. Let me know when you need $. Ask these guys what they are doing for selector keys? I got two of the remanufacured ones from Alen. To make a long story short I found myself needing to split my cases after maybe only two race weekends and an hours worth of breakin. I had a new selector rod, key and mainshaft instaled. Upon inspection the new key is not holding up to the task it was intended. I emailed Doug wilford and he said he had one of the new keys break right off. It seems some one didn't do the metallurgy. The stock parts in an engine are made to specific metallurgical formula with one of many different types of heat treatment to achieve the desired strenght and hardness. If this isn't done right you end up with failure! I'm hoping Mr. MZ knows the right fomula. In the past I tried to get information about the sraight cut gears on this web site. I have an advertisement in dirt bike magazine Oct. 73 page 102. Grand Prix Cycles of Santa Clara California  distirbuted the gears and the add says the gears were made by CMS products of Mountain View California. I hanvn't been able to get any additional information about the type of steel used and the heat treatment process used. The add did say the gears "are machined out of solid steel by CMS and then heat treated for exceptional strenght". Mark AAnnan has a set of these gears. Wouldn't it be advisable to send these gears out to a metallurgist and have them tested for composition and hardness so we know we are at least getting something comparable in quality. I'm sorry if I seem like an alarmist but $300 is a lot of cash for an untested part.  I am in for one set. Keep us updated. Gavin Housh

 
Title: Straight cut primary gears for a Sachs
Post by: john durrill on July 17, 2003, 11:41:45 PM
Gavin,
 The enginer was the head of MZ enginering department.
 MZ built some very good and tough bikes.
 Martijn is supplying a gear set to use as a model. Ing. Muller has already built gear sets for Martijn and they have been tested road racing. I think we should be safe on that count. who ever Ing Muller uses to produce the gear sets knows how to make motorcycle primary gears that are strong enough.
 on the shift keys. you could try Martijn and see if he can supply them.  He should have a source. He Road Races 1 , 125 Sachs engine bike that he has converted to liquid cooling and rotory valve. He also builds 50 cc RR bikes and sells them . designs and builds  his own frames.
 we could try the Hammers in Germany. they sell parts for the 125 military engine and the key is the same for the ones built from about 71 up.
 is Al B selling reproduction Shift Keys?
 I didnt Know that.
 We should know something shortly on when to send money. i think we send some  when they start the design work and the balance when the gear sets are done. will keep every one updated as soon as i know. Martijn is in contact with Mr Muller every week or so.
John D.

Title: Straight cut primary gears for a Sachs
Post by: john durrill on July 19, 2003, 01:11:09 PM
Here is the latest on the gear sets,
 Its a note from Leo.


Hello John ,

I just phoned with Ing. Mueller.
10 units would be ok. He had no idea how to manage the payment. Money
order
is very expensive and paypal, cc and other things are unusual for
people
that are not involved in business.

Best would be:
Martijn has the original that Ing. Mueller needs to have. He also needs
a
Sachs 125 motor.
Mueller will contact Martijn to get the parts (they will meet in
Belgium/Spa
raceway in August).
Martijn will have 50% of the order so he has to pay 50%.
If Martijn makes the business with you, he could pay your part also.

Leo.

Guys,
We may just be able to do a western union money order or do it through Pay Pal . will check with Martijn and see how he could best recieve it.
 On the change in gear ratios ,No we are contracting for a Gear Set like the Sachs factory made for special race bikes
Will double check on the ratio and make sure.

Looks like the gears are in production as of now. we may need to send some monies to Ing. Muller.  I suggested half now and the rest when he is ready to ship the gears. we need to get things ready to do this.
 There are 5 of us In the POG group that placed a request for the gears. could all of you reply to this post and let me know how you would like to do the mony transfer. I think we can send Martijn the mony and he can get it to Mr Muller with thee least expense incured.

Folks i look forward to the new gears,
 I'm told that they add 1.2 HP to a B engine.
 the great thing is , its a mod that is free HP. there is no down side except a slight increase in engine noise. the crank and lay shaft should have less drag ( side load ) at all speeds and that should make the bikes produce more power in a smooth curve from idle up to max RPM.
 It's like fixing a rear brake lever that was stuck and had the brakes draging slightly all the time.

 One more POGer to go and will send the monies to Martijn.
Would like to send a note to Ing. Muller (Martijn will translate it for me into German). We should know a lot more after he recieves the note on specifics.

Latest update folks,
 the monies arived in the Netherlands ok and will be headed to Ing. Muller. Below is the last note from Martijn.

Hello,
 
Sorry for my slow response.
I catched a cold ,so was out of business for some days.
 
I found a PayPal message saying 750 dollars arrived.
 
I will tell Mr. Müller this tomorrow.
 
The ratio will be as the original,or as close as posseable.
The whole thing will run on caged needle bearings.
 
Best regards,
 
Martijn Stehouwer

John, happy holidays. Any word from our friends over sea? I am hoping to have my bike ready in march. I  tryed to get ahold of Jake Fisher about those keys but all I could get was a fax machine on the other end. The other number went to his house I guess. I got someone on that line who told me to try the other number, which is connected to a fax machine? Gavin

John, sorry to here you had to go under the knife. I hate those frigin doctors, but I guess they have prolonged my life on two seperate occasions. Not to mention the knee fix twenty seven years ago, and I still walk, run, bicycle, work, and ride motorcycles. I hope your neck problem (it was the neck wasn't it?) heals quickly and lets you put that old helmet on soon. Thanks for the update on the gears. Sounds like everything is moving along. Happy holidays. Gavin

I know I'm a bit late in the discussion. I'm the one that installed the needle bearing and wrote about it! The main reason for doing it was that I had some play on the bushing and the hole didn't seem to be centered so I got cold feets and suspected possible cage wobble which could mess up the primary gear wheels! I figured I couldn't go out and buy the bushing for a couple of dollars but the needle bearing is easy to look up!

The conversion to straight cut wheels is better. That's just the way it is! A gain in HP and less side forces all the way from the crank to the shaft. I know that not everybody likes it but with straight cut wheels, one can go for another type of crank bearings too.
Of course It's not the designers intention to do so but neither is straight cut wheels. I don't care though :D  

Merry Christmas and a happy new year!
It's snowing heavily here at this time, huuuuh!

Folks,
 the gears should be shipping with in two weeks. the cost to ship 15 kg's (33.075 lbs) is 80 dollars euro. we just weighed a set of the stock primary gears and they weigh in at 1 and 1/2 lbs.
converstion for kg's to lbs is 2.02 lbs per kg.
 looks like the gears should weigh in at less than 4 kg's (dont know how much the packing and box will weigh).
 will keep you updated on when they are ready to ship.

Folks ,
 Just recieved an update on the gear sets from Martijn. Will post it below.

hello,
 
I have a very unpleasant message for you.
The primairy will take more time.
A stupid mistake was made.
When I got there the little gearwheel had
the cone of the ignition system as mounting point.
Which means they now have to make new
small gearwheels..
I am very sorry..It is a stupid mistake.
 
So you will have to wait longer ,I asked to hurry
things ,because racing saison son starts.
Some of my Dutch customers also wait for the things.
 
I have some clutchplates in stock.
 
 
EMOTracing

 It looks like it will be a month or so. I know Martijn is turning the burner up because he has customers waiting on some of the gear sets.
It seems nothing we get re-poped is quick. I know Al B spent a year with a vendor testing the Petcock repair kits befor he got kits that would work right. We ( Al , David Haines , and myself) spent 6 months working with a vendor haveing replacement swing arm bushes made for the 100/125 Sachs engine CMF Pentons. 6 Runs of bushes were made befor we got sets that were up to the orginal standards.  We are still waiting on Euro Rods for Rod kits made up for the 100/125 A and B engine and the 175 piner. I have one of their kits in my bike and it had to have the rod pin turned down .045 in length to fit. We had Falcion do the work and it was not cheap chuckle chuckle! .
 I know this is no help with the time frame we are looking at . Wish we had better news and will keep you guys updated on how its going.

Hi John,
Sorry to hear the news about the gears,[V] but very interested in the rod kit project. I have to tear down the six day I recently aquired and give it a once over, so I have plenty to do. I'm glad to hear about your brace coming off. If it's like the one Bob Wardlow is wearing in the photo section, you probably don't sleep to well![:o)];)Anyway, thanks for the heads up.

Folks the gear sets are ready to ship.
 we need to get our monies in one place as soon as we can.
 the note from Martijn is posted below.

Hello,
 
We must contact...
The primary gearwheels are ready.
They are very nice.
They costed 250 euro each.
Makes 1250 euro for 5 pieces.
Or maybe you want some extra?
you once sent 750 USD of which
720 USD reached me ,the rest went into
bank transferring costs.
You also need clutch plates ?
Conrods? pistons?
 
Martijn Stehouwer

Here is the conversion from Euro to US dolars today

Powered by  
Thursday, April 22, 2004

1,250.00 Euro = 1,479.50 US Dollar
1,250.00 US Dollar (USD) = 1,056.10 Euro (EUR)

Median price = 1.18300 / 1.18360 (bid/ask)
Minimum price = 1.18130 / 1.18180
Maximum price = 1.19150 / 1.19180


 Shipping will be above the 250 euro for each gear set.
Please let me know as soon as you can on when you will send the monies.
I can cover the shipping till we know how much it will be to deliver it to your door. Is that agreable with you folks??
Notice he has clutch plates , rod kits and pistons for any that have a need at this time.

Robert,
 Here is Martijn's web page. He has rod kits listed for the Sachs engine.
http://www.emot.nl/webstore/catalog/default.php?manufacturers_id=21
 I bet they are for a B motor. A motor kits  are different. the Hammers in Germany should have the A kits
http://www.motorrad-klassiker-ersatzteile.de/html_eng/index.htm
 Both would take Pay Pal last time we bought from them.
Does this help?

John,
  Thanks, that will give me an option. I sent Donny an email inquiring about availability from Larry's stock, and haven't contacted Al yet either, but it's good to know Martijn has some out there also. I haven't pulled the Six Day apart yet, but I did get the flywheel off and the cracks in the engine case are fixable. Just need to get the magneto area sealed up from the elements.
  If I read your earlier message correctly, the conversion to US$ would put the gear sets at $295.90 ea. My notes show I should owe $95.90 plus shipping. I'll send some extra for the bank transfer costs plus the shipping to your Paypal address if that is ok with you. Just say the word.

Robert,
Yes that will be fine. I am waiting for exact prices from Martijn now but they will change slightly every day with the Euro to USD exchange rate. We can figure out what to do about the small changes once the gears are sent. The bank transfer charges he spoke of must be for transfer from Martijn to the MZ enginer in Germany. Will let everyone know as soon as i do. At least we can split the changes 5 ways and that helps each of us.

Robert,
 send Doug a note on the case repair. He had a welder , local to him , that was doing this at a fair price and Doug was happy with the work. I think he told me that they made up a replacement piece from sheet stock and welded it in. It been almost 2 years since we talked about it though.

John D,
I ordered the gears from Matijn about three weeks ago.  He recently sent me an email indicating that he was delaying shipping because the gears didn't fit SACHs with oil pumps.  He said he would ship imediately as soon as I confirmed my engine didn't have an oiling system.  I sent him an email indicating no pump on my engine and I presume he will ship my gears imediately.  Have you heard anything about this?

Gary,
 If you have a cranshaft that has a slot cut on the primary gear side, has no threads back about 3/8 of an inch from the end, then the gear set will not work.  The slot was used to drive an oil pump.
Send me an e-mail if you like and i can go through fitting the gear sets. We are doing that to my engine now.
