Starter Help
Guys i have a weird one..... the jack shaft bolt wont stay tightened. It first had broke the tab on the washer, so i went and got a new one today. Well i loctite the bolt and put the new washer and washer with the tabs on it and tightened it down as per the manual and hten bent the tab down over the bolt head and before i put the primary cover on i hit the switch and the bolt just loosened up and came back out. Has anybody ever seen this happen and what was the fix???
Thanks in advance, i know there is allot of knowledge here.
btw the bike is a 99 ultra, TC stock 88

There is no need for loctite on that bolt.
It the locking plate (washer) is properly installed, I can not imagine how it could move on its own.
You put the long tab so that it's keyed to the shaft and then bent the outer tab up to one of the flats on the head of the bolt, right?
If so, it can not loosen up w/o bending the tab back down...???....

Thanks guys but yes the tabs are correct and yes the bolt gets tight, and yes i did use locktite and yes i did let it sit.....for a few hours....and as soon as you hot the switch, the gear slides out and engages then the bolt just startes to spin....

Are you saying that the bolt just unscrews itself and comes out, or that the pinion gear engages the ring gear but does not turn the ring gear when the starter runs?
It almost sounds like you are indirectly describing the latter.... which would be a bad starter clutch. Bad starter clutch is a reasonably easy fix, but you also want to fix the root casue ~ which is usually too much timing advance during start up or too much compression w/o compression releases.
Does your bike ever "kick-back" when you are trying to start it? THe kick-back is what destroys the starter clutch... timing or compression creates conditions in which kick-backs occur.

Philm....i even took the plugs out to make it easy to turn it over while i was testing the bolt to make sure it would stay in......but it still just un-screwed all the way out.
