jackpiner clutch plates

[johnnysurf1]

not being able to locate clutch plates for my jackpiner, i sent my plates to barnett and for $75. they rebuilt them and shipped them back to me. i'm going to send them the ones i take out,and have a backup set.they don't make new ones or have the steel discs,but my discs were o.k.just the friction material was bad.

Will they give a dicount on plates if you have a lot of them? Will they do 250 and 400 plates? I would like to find out, maybe as a group the price would get better. I know there is alot of old plates out there. Later Gary

i called barnett tool&engineering at 805 642 9435,and asked for xavier[he is a technician]i mailed my old disks to:barnett tool& engineering,2238 la palma drive,ventura,ca. 93003.it took about 2 weeks,he tried to match it up with another one in production,but ended up rebuilding them.i was hoping he could match them with over the counter ones.i have not talked to him since,so i don't know all the details,but for $75 shipping included they arrived ups.....johnny

Were your Jackpiner discs the organic style or the sintered bronze? Mike

Very resourceful, thanks Johnny.



8 nos copper plates. Does anyone know what KTM these are for ? Outside fits 74-78 clutch basket - ID = 108 mm (larger ID than the common 74/78 organic plates) - thickness is .081".


7 ea. nos aluminum plates. Fits 74-78 KTM clutchs. In the parts manual it says the aluminum disc's (non organic) are for 125's. But no mention about the aluminum organic discs.
Does anyone know if I can I use any of these on a 250 engine. ?

Thanks in advance.

Bob,
I am away from home where my Engine parts books are, but they look like the early Penton/KTM plates 1973-76, only 2mm instead of 2.5mm or 3.5mm of the 250 and 400 plates. I will look them up when I get back home Friday evening. Gary Ellis may know more about using the aluminum plate organic discs. My guess would be that they are 125/175 discs. Mike

Bawb those plates fit my bike. Number 1 photo 8 nos copper plates are for 1980 thur 1984 250, 420, 495. Number two photo is for a 1979 to 1980 125,175 . If you do not wish to use them I would like to trade, or buy them if you want. Hope this will help. Get them motors out of the frames so I can get start on them.  Later Gary
