Loud grinding on start-up
 

258 YJ, Peugeot trans. When I start it cold, I get a loud metallic
grinding sound. Rev the engine to 2,000 RPMs for a couple seconds and
it goes away. Sounds like it could 'possibly' be coming from the pilot
bearing. I replaced my clutch this spring but left the pilot bearing
alone because i didn't have a puller and the clutch I had in there only
had 20k or so miles on it. Assumed it would still be OK. Anyway, if I
start the engine warm, no sound. Looked at the Haynes troubleshooting
section, no mention of such a sound. Tried starting it cold in neutral
with the clutch engaged with the same results. Thoughts? Thanks.

Re: Loud grinding on start-up
 

If it makes noise when the clutch is engauged, it isn't the bearing
because it isn't moving then.

I would suspect a loose pressure plate bolt maybe.

My BA10 had the same noises. They got progressively louder until I pulled
it to swap in an AX15. The thrust bearings on the input shaft had given
up and the noise was the input gear grinding on the slinger washer.
Needed the input shaft for a clutch alignment tool, didn't bother
re-assembling the rest before trashing it. I'm no fan of the puny French
5-spd.

Re: Loud grinding on start-up
 

That sounds like it. Guess I'll start looking for an AX-15. I've
wanted one ever since day 2 of owning my YJ when I found out my
transmission was made by the French.

And since the general consensus is it's not my pilot bearing, I guess I
ASS-UMED right.

Thanks guys.

Re: Loud grinding on start-up
 

Why are you looking for trans problems? I've re-read your post and
nothing in it suggest the transmission is making a noise... what happens
when you start it out of gear without the clutch depressed? If it has
clutch start then disable it.

I would be looking at the starter, and the fan clutch and work my way in
from there.

I'm siding with Simon, here -- you've absolutely ruled out the pilot
bearing by starting in neutral with clutch engaged. You'll absolutely
rule out the transmission if the noise occurs when starting in gear,
clutch disengaged.

Re: Loud grinding on start-up
 

With that BA10, you really should do one more step: tc in neutral,
transmission in various gears. There are some strange interference
possibilities in the BA10 if the thrust spacing is buggered. That should
pretty well eliminate the transmission.

BTW, the BA10 - AX15 swap is NOT a drop-in swap! Do a little research
before you start it. All sorts of bits and pieces get involved, some
being real PITA stuff - like the transfer case input shaft and the pilot
bearing.

I see no evidence to indicate that your TO bearing could not be
ultimately at fault.

ASS-UMING anything is never a good thing. I say a teardown is in order.

You're both ASSUMING it's the transmission for no good reason.

You have a point, Simon. It's as good a place as any to start I
suppose. Back in the good old days, we used a screwdriver or piece of
rubber hose up against a suspect part to find out exactly where a noise
was comming from. The ear doesn't work neary as well as it should for
this sort of work.

You have a point, Simon. It's as good a place as any to start I
suppose. Back in the good old days, we used a screwdriver or piece of
rubber hose up against a suspect part to find out exactly where a noise
was comming from. The ear doesn't work neary as well as it should for
this sort of work.

The pilot bearing 'cannot' be the problem because the noise exists with
the clutch pedal up which means the pilot bearing is 'not' in use at
that time.

The pilot bearing only spins when the clutch is depressed, otherwise it
is fixed solid to the clutch.

A bolt coming loose from the pressure plate after a clutch re+re is not
unusual at all though....
