2b) Are they at least serviceable?
My tube come out of the rear end, then goes up to the sight glass/sight tube (same thing), then goes up to a fitting higher up on the rear end.This clear tube. Is it supposed to be connected to somewhere else on the transaxle. Was just reading about this in another thread. Mine is just clipped under the fenders. Also, I read something about a sight glass. Where would this be and what is different about that and the sight tube in the back?
