Pilot shaft bushing wearing fast and often!!
Hey Group,
My 84 CJ7, 258, T5, Dana 300 is about to get it's 3rd pilot shaft bushing
in 15,000 miles. Seems like every 5000 miles or so, I start getting a weird
grinding sound as I'm down-shifting and slowing down. I yank the tranny and
the pilot shaft bushing is worn and allowing the input shaft excessive
movement side to side, probably .015" to .020". I've placed a thick felt
pad behind the pilot bushing soaked in 90 wt gear lube, I've put wheel
bearing grease in, on and behind the bushing, I've replaced the input shaft
on the tranny, I've looked for any obvious signs of mis-alignment in the
drive train (no body or suspension lift). It's not a huge job to change the
bushing out but I'm getting tired of doing it. I really just don't need the
practice if you get my drift. Does anyone have any idea what may be causing
this? Is there a pilot bearing made for 4.2 jeeps to replace the bushing? If
so, who sells them?
Any and all input appreciated,
Thanks,
Charles E.

Re: Pilot shaft bushing wearing fast and often!!
Input shaft bearing? Bearings between the back of the input shaft and the
front of the mainshaft? Transmission to bell housing alignment? Bell
housing to engine block alignment pins? How are you installing the
bushings? If you hit them wrong they can be damaged. If this is a sintered
brass bushing, then it is supposed to have something like engine oil soaked
into it, probably the felt pad too. The only likely thing I can think of,
is that you are getting new old stock bushings that have dried out in
storage.

Re: Pilot shaft bushing wearing fast and often!!
The YJ comes with a bearing instead of a bushing. The bearing can be
made to fit, but the inside would need to be machined slightly to take
the different tranny shaft diameter. Not a lot mind you, but it could
be a bitch with a rat tail file....
The stock bushing uses 10W30 engine oil on a felt pad and should be
soaked.
I think the OP is maybe running them dry by using gear lube and grease.

Re: Pilot shaft bushing wearing fast and often!!
The YJ comes with a bearing instead of a bushing. The bearing can be
made to fit, but the inside would need to be machined slightly to take
the different tranny shaft diameter. Not a lot mind you, but it could
be a bitch with a rat tail file....
The stock bushing uses 10W30 engine oil on a felt pad and should be
soaked.
I think the OP is maybe running them dry by using gear lube and grease.

Re: Pilot shaft bushing wearing fast and often!!
Hi Mike,
I've never heard of using a "The stock bushing uses 10W30 engine
oil on a felt pad and should be
soaked." seems like you would be asking for a heck of a chatter. A disk
is like brake shoes, we can't even leave body oil on them.
