Lower crank pressure question...

[Oldebonz]

No shame whatsoever! We have all done similar or worse brain farts!! It's just nice to figure out the problem and understand why!

Hundreds of views on this topic...my guess is more then one of us will make a mental...or written...note to ourselves to double-check direction   of seal installations...just to be sure! [8D]

I have always gotten seals in the right way but I once holeshotted a National and ran the bike out of gas shortly after the first corner because I forgot to turn the gas on.  None of us are immune from brain farts.

Along this same topic but on a Puch does anyone have opinion on seal direction?  Puchs are DIFFERENT from most 2 strokes.  The crank bearings are not lubed by 2 stroke mix.  Both crankshaft seals are directly against the flywheels and then the bearings.   Unfortunately shop manual says to place seal lips one way and parts says the other.  Have seen them both ways.  Ideas?

Get a hold of Matt at Motor West in Milwaukee.He is THE Puch guru.

Most older Huskys have the clutch side seal inboard of the lh main bearing...that bearing is lubed by the clutch/trans fluid...so that's not unusual. On the mag side the rh bearing is inboard from the seal...lubed by the pre-mix "mist".
However, on the PUCH, how would the magneto (dry) side bearing with an inboard seal get any lubrication?
Just wondering...[?]

Puch has a slot with a slinger that lubes mag side with tranny oil.  I spoke with Matt some time ago and he didn't remember.  I have several Puchs and haven't had mine apart in years so can't remember either.
