Throw out bearing and slave cylinder

[CruisinTiger]

Ok so I have an 86 fj60 and as far as I can tell there is no adjustment for the slave cylinder and unlike earlier 60's there is no spring on the fork. So here is my situation, a year or so ago I swapped out trans anf tcase and all new clutch, flywheel, etc. but the other day my buddy and I were looking at the clutch as the truck was running and the throw out bearing was spinning along with the clutch. I also get a "noise" when I press the clutch pedal and change gears coming from the clutch/throwout bearing area..kind of like a clinking. I believe the slave may be original, I know I've never changed it and I've had the rig for 100,000 miles, so I know this has to be done. Will changing the slave bring less, or I should say original, pressure back to the fork which will disengage the throwout bearing?? Or is there another method to the madness?

Thanks

It is my understanding that the late FJ60 set up keeps the throwout bearing under constant pressure on the clutch cover/ pressure plate.

In other words, what you're describing is normal.

The noise could be a bad throwout bearing. When under full load it could be making noise. Done any water crossings lately?

Bleed the clutch/ change the fluid if you think something funny is up. It would need to be leaking to be a bad part.

Thanks for the info!

Just curious .....
If you press the clutch in slightly does the noise go away and return with the pedal is realeased?

Can I jump in here?

Yes, that's what mine is doing. Lots of noise from inside the cab and underneath from the clutch area when idling. Press the clutch in slightly, the noise changes. Press it in all the way, noise gone.

Throw out bearing? Can I lube it or anything without doing the whole clutch job?

Clutch only has about 50000K. WTF?

Thanks, and sorry to the OP for jumping in.

Mine does the same thing. What did you end up doing?

If the TO bearing isn't adjusted right it will intermittently rub on the pressure plates, causing a scraping sound because there is not enough pressure on the bearing. When you clutch in, the force of the slave holding it against the plates will cause the bearing to to spin, eliminating the noise. That is what mine was doing before I fixed it.
If you have a later model, you need to adjust it so the TO bearing is always held firmly against the pressure plates.
If you have an earlier model, you need to adjust it so the TO bearing is held like 1/8" away from the pressure until the clutch is depressed.

I have a 1987. Is this something I shouldn't delay in fixing? I drive the vehicle to the store once in a while etc. it's our fun car, just short trips here and there no more than an hour each way, max. Just wondering if I can go a while or it's something I should start this weekend.

 

[LAMBCRUSHER]

can you still shift? then you're good there isn't much if any adjustment on the later to bearings...

 

[BigIronPilot]

I can still shift.

I have the same thing..
If the clutch is out... noise.
If the clutch is in... no noise.
I just did a transfer case rebuild and new rear main seal, and put it all back together and completely forgot to do my TO Bearing..
Anyways you can drive on it forever, it will just bug the crap out of you haha.

It bugs the wife more than me she thought it was a huge deal since we just bought it. I'm sure she was thinking "oh great!" What about slip in the steering wheel? Mine has a ton. I was searching earlier but there are all sorts of random stuff.

I have a couple ideas for thought.

Do you hold the clutch in for long periods (more than 5 seconds) in traffic, at stop signs, at lights etc?

What may happen is this- The throwout bearing is sealed, and is greased prior to assembly. When you hold the clutch in, it spins with the pressure plate under pressure. This causes it to heat up. If you leave it pressed for too long too frequently, it will overheat and start to spit out that grease.

Eventually, there is little to no grease left, and the bearing starts to stick up. This may be a part of the problem?

With your slave- If you use the clutch as i mentioned above, that can put more stress on your slave internals and cause pre-mature wear inside the cylinder. Mine started sounding like a creaky door when I wore it out standing on the clutch in traffic.

just a thought

Explain the slip? is it just sloppy? Have you replaced your tie-rod ends, or any other steering components?

To rule out throw-out bearing noise vs transmission noise,

1. Remove the inspection cover under the clutch.
   
2. Start the car and let it idle
3. Go under the car and move the release fork so it pulls the T.O. away from the clutch cover. It's easy to do.
   
4. If the sound goes away, the sound is the T.O. bearing.
5. If the sound remains, it's the transmission.

Also apply a little more pressure to the release fork to apply more pressure on the bearing... If the sound changes... it's the bearing.

great, thank you! how do I fix my steering wheel slop? I've been searching all over and there is a million different things. I can move my steering wheel a good 3-4 inches before it has any input. I read something about adjusting a nut and bolt on a gear box. Where is that located?

I have the clutch bearing issue as well. My clutch held really really high, replaced the clutch and all the innards and she still engaged in the last quarter of the pedal stroke. I adjusted the pedal height to make sure my clutch actually fully engages and now I have the sound. Pedal in, sound gone, pedal out sound is back. The bearing is brand new . In my case I think my master was replaced by po and it does not look like its the right part. There isn't any adjustment on it. I must get that sorted first, then adjust for bearing noise. Problem is I have a diesel hj60 and as far as I see there is non inspection cover so I cannot really see what's up in there.

I'm just going to roll with the noise for now. I finally fixed my steering problem at least. It was semi dangerous for a bit there, real experience driving on the highway.
