1987 K75 s For years I’ve always wished I could stop an oil weep coming from the TOP of the lower crankcase half just under the engine block and on both sides. I decided then to put up with it. Several weeks ago I needed to replace the darn clutch O-ring and track down a vacuum leak around the T.B’s. One thing led to another and the frame is removed from the motor. The motor is now sitting on the work bench with the T.B’s off along with the bell housing and yes, the water pump needed to come off as well as the rear main seal to address taking the lower crankcase off to reseal. Clymers makes like that after you turn the motor upside down, take all the bolts out, carefully lift up the lower crankcase so the output shaft stays put, put in two new O-rings then reseal. Other information I’ve read is that the output shaft is under tension and stuff could go flying. Any thoughts? and yes another sealant question, what kind do I use there. Mike #132524
