1990 FLSTC ~60K miles; original clutch, rebuilt 5-sp 20K miles ago;
Symptom - at engine shutdown while in neutral, slight gear wind-down noise from inner, rear primary; sounded like a bad bearing
tear-down:
primary chain and tensioner look fine, no metal shavings on primary drain plug
R&R clutch bearing, but was not bad
removed inner primary, front belt sprocket rubbing on transmission case
rotate and manipulate main tranmission shaft and seems fine (no play, no noise)
have heard that 1990 front sprockets were poor and that the splines wear allowing the sprocket to move; very tight tolerance to case
plan to remove sprocket tonight and check inside splines --> splines slightly worn, but not enough to be causing problem; noticed damage to back side of sprocket during dissassembly that was causing rubbing on transmission case = $200 new sprocket to prevent future spline problem and fix rubbing
replaced all seals and bearings in inner primary and hope low bearing growl goes away due to pilot bearing
Anyone else experience similar problem? Bill
