I just had a rear bearing cap fail. Upon taking it apart it had a shortened drain tub. Most of the thrust was gone on the rear and about 20% of the bearing surface. Crankcase back-
pressure could come in to the question, also 8% mile and a half grade on every trip to town. Is going down hill worse than going up, is the oil in valve chamber to low to feed the rear tube to bearing? I put it back together with a stock drain tube, 3/8 in.
