Still marble chatter???

Wow,well you learn something new everyday! Thanks fellow XJ'ers

 

OK so while waiting for my kit,I pulled my starter apart, cleaned a little,measured my brushes (10mm) an regreased the reduction gears. Still having the starter probs when engine is hot. Could a dirty armature and commutator alone cause this considering my brushes are still OK?

 

I started getting issues from the starter clutch after switching to synthetic (Amsoil) as well. As hot as the oil gets in summer, though, I'd rather deal with a bit of chatter than having to change oil every couple of weeks.

 

You know it might be that the starter clutch really is broke.

 

Well, not broke, but probably worn. They seem to become more picky about oil and less tolerant of a weak starter as they get older.

I also need to better tune my cranking pulses so that I can get the bike to start more quickly when cold. Usually the clutch grabs for a couple of seconds and then lets go. If I can get it to always start in that first couple of seconds (as it does when warm), the issue becomes moot... or at least gets deferred until it totally wears out.

 

believe me, they crack into three pieces. and the still work.... sometimes.... if they catch just right

 

Yep. And the springs can weaken after 30+ years too. An oil change can only do so much.

 

Very true. But I'd sure hate to split my crankcase only to discover I really needed a starter instead.

 

I just replaced my starter. I had the same problem. The bike would start every time cold but after even a 2 min. ride it acted like a dead battery. New starter and my problem went away. But then again my starter was f&$ked.





Hope this helps.

 

well he changed oil twice and had the starter apart twice. now what would you suggest.
could change the oil one more time, but i'd keep the oil.
or jump the starter right to a car battery, that's as much as the starter could give.
i really think mine was broke in three because the po just kept beating it, it broke three places and things don't brake three places all at once

 

Well the PO must've rebuilt it not long ago. It looked fine,nothing like other's pictures. I still rebuilt it earlier an I'm gonna get it on in the next day or so. I'll try hooking it up to a car battery when got if it continues. After that if it still does it,maybe it is the starter clutch

 

A good pencil erased has been used to effectively clean electrical contacts ( especially in computers or small electronics) for years yes it works very well but make sure to use some sort of spray electricalncleaner or equivalent to remove any residue when done. I use erasers all the time for this and it wont hurt. I use those big pink erasers you get that have the slamted wedge shape on each end.
