Helping grandson on a clutch replacement - grease questions

96 6 cyl manual trans, clutch is being replaced.
- a few questions please.
- do you put any thread locker liquid on the pressure plate holddown bolts? just a dab?

- a manual says to put grease on the:
- pilot bearing
- face of the release bearing that touches the clutch fingers
- the release fork where it touches release bearing
but how much grease and what type grease?? grease is bad for clutch facings duh!!
Thanks in advance

First when you install the pressure plate, make sure you tighten then in a crisscross pattern,a little at a time around the entire plate with the alignment tool centering the plate. Second, on most throw out bearings, there is a recess built in. Fill the recess around the perimeter on the inside of the bearing so there is grease in the recess.Slide it on the shaft and move it back and forth( then remove the excess grease off the shaft). This allows the grease to constantly lube the shaft.Put a light coat on the splines of the trans and wipe off excess. This will keep from getting a crunchy pedal.When they say to put grease on the fork and the face, they are talking a small amount so where the steel rubs steel, it will not squeak when engaging or disengaging. You do not put grease on the clutch disk,flywheel or pressure plate faces. I have always used a high temp synthetic grease. Hope this helps

the haynes manual says:
fill the inner groove of the release bearing with hi temp grease
=======
any idea what "inner groove" they are talking about?

??are they talking about putting grease
-1. just inside the front of the bearing where it presses on the pressure plate fingers (seems that location might sling grease on the clutch face)
or
-2. some groove in the body of the bearing where it moves back and forth when you press the clutch?

The part that slides onto the input shaft of the trans (which is the throw out brg.)is what they are talking about. on the inside of that there will be a recess. that is what you fill with grease. It is just a groove that is cut into the center and as it slides on the input shaft, that grease will continuously lube the shaft. does that make sense?

yes thanks, we are ready to install the trans and did not notice a groove, will look again, maybe our bearing does not have one?
the confusion on my part was finding the groove location , and grease can mess up the lining of course --, it is not in any manual (looked in 3) that I could find nor on the web --
lots of words for a simple thing but here goes-------
The groove apparently runs down inside of the bearing in the area of the large hole in the bearing that fits over the input shaft (and the groove thus runs fore and aft in the car in same direction that the bearing moves when you push on the clutch? right?
NOT the very small recess around the very engine side EDGE of the bearing where the rotating part of the bearing touches the clutch fingers , have I got it right now ?

The number 2 area is where you will grease. Fill the recess and install it on the shaft. clean the excess off tha shaft after moving it for and aft. also make sure you put some grease (a light coat)on the fork point so it will not squeak. Also, make sure you lube the fork fulcrum point. It is the ball and socket part that the fork pivots on. Hope this helps. Here is a second pic i found

Yeah! its all coming together there was a small groove, the pix you posted were great, we got it back together, slave cyl not on yet
cold today in south carolina. cold 4 us that is.

this is a recently new to my grandson 89 yj body with a 1996 xj engine (4.0 six) and 1996 AX15 transmission.

when he put the xmission to bellhousing bolts in place the 3 and 9 oclock ones went in fine - these are the one that go thru/near the dowell alignment holes. that left 2 other at about 11 and 1 oclock. the 11 oclock one went in fine and tightened up fine,
the 1 oclock one either we had a too small bolt due to a mixup or the threads had been rung off. it goes in but does not tighten at all, probably been that way 4 years.
questions please.
-are all the bolts in this area the same thread and length?
- if we have the correct bolt, what is the fix?
- ignore it and just have 3 bolts?
- use a bigger bolt and "force it"
- put in some type screw in insert? its a hard to get at area I think,

do the trans to bellhousing bolts dead end in a hole or do they go throught such that you could put a nut on the backside? his jeep is not here at my house so I could look at it

I believe they dead end in the bell housing. Most all the bell housing bolts dead end also. 2.5L there are a couple on the bottom with nuts to hold the dust shield. Not sure about six cylinders.

For the one that is stripped out you will need to do a Helicoil insert. it is the best way to do it. they sell them at auto part stores. take the bolt with you when you go to get one. That way you can make sure the thread pitch and size is the same as what you need.
