 Posted: Mon Mar 23, 2009 4:36 am Post subject: Cluch O ring problem |
 |
|
Its the "three wheeled" guy again  On the 1990 K1 16v engine/gearbox I have I stripped out my clutch to address the oil leak I developed after going in to fix last years starter clutch issue I had , the main engine seal was fine the oil was coming as a slight weep from the clutch centre nut area , my question is when I assemble this loosely to figure it out the raised section on the washer behind the nut doesnt look like it compresses the o ring ? I cant see how the o ring is going to seal unless its under slight compression from the afore mentioned stepped washer , I can see the output shaft splines and the clutch carrier splines and they end up flush with each other , is their something else in here I may have have lost , the Clymer manual diagram doesnt show anything else nor does the real oem parts fiche ? I am almost thinking of jamming in two o rings ? but I know this is a bodge , has anyone had a leak at this junction ?
Apologies for being a bit long winded !
Regards to all
Bill Black

1) O-ring
2) Thrust washer
3) Cltuch nut
That's it.
Be sure to torque it, loosen, retorque as described in the manual.

Thanks for the reply Duck have you ever had one leak here before ? I know I used a new o ring and torqued it up correctly the first time

I replaced a leaky one on a K100RS4V, torqued it properly and the leak went away.

Hi Bill,
That was the source of a leak on my K1100 at 125K miles. I just reassembled with a new o-ring (coated with silicone grease this time) and it's still leak free at 146K. The sequence is Thrust washer, Clutch housing, o-ring, thrust ring, nut.
Use the procedure in the service manual to seat the housing and then re-torque.
Mick
