clutch HELP please 1986 3.2 QV

I'm stuck...ready to remove the bellhousing on a Mondial 3.2 QV but...I can't get the bearing off the input shaft.

Some have suggested walking out the bellhousing 1" to release the bearing...and I did so...but it is still seized on the shaft...and stays put even after moving the housing back and forth a couple of times.

Any suggestions? TIA

 

Is this the inner bearing you are talking about or the outer one? (i.e. have you removed the lower drop gear yet or not? )

 

Ok...I've removed the ring nut ...VERY difficult...took 400 lb ft...this was after heating-up with acetylene torch....turned out it had lock-tite on it....is this factory locktite? or??

and then removed outer bearing ( did not see this outer bearing on the tutorials for the 308) and then removed the lower drop gear ( turns out I could have removed both together with a puller...I did not know this....as the gear has three tapped holes for a puller)..

...and then I removed a snap ring....and now..I'm staring at another bearing ( this bearing rides on a race pressed into the bellhousing)

Thanks for any advice

 

Ring nut shouldn't have been loctited, the edges should be peened in to hold it. The outer bearing is there on the 3.2 but not the 308 it seems. I had to use a 3 legged puller on mine (my lower dropgear doesn't have the 3 holes in it for a gear puller).

As per your original post, the inner bearing should just "walk" its way off the shaft if you move the bell housing as you described. So I'm at a bit of a loss as to why it would be stuck. I had no problems with it when I did the clutch on my 328 a few months ago.

Is it moving along the shaft at all? Once you have removed the snap ring there should be nothing to stop it doing so. Can you walk it out far enough to then be able to get a puller onto it?

 

Nope...won't budge at all...just my luck...simple job is turning out to be a nightmare...taking 6 times longer than planned..every step of the way.

I guess the locktite indicates this might have been apart before eventho it's only got 18k miles on it.

I am thinking that if I can get this bearing out...then there may be a spacer and snap ring.

I have a dream that if I take a crazy chance and pull the bellhousing...and start banging the housing against the bearing...it will budge? Maybe not..as it really seems immobile on the shaft.

Or I may have to cut the bearing off?

Anyhow, kind of you to post a speedy response to my query....Thanks

 

have you tried a bearing puller?

 

What does it look like? How does it work? Maybe half-round legs with very thin feet to fit under the center race?

May have to make /alter a puller to fit...or cut-out the bearing and buy a new one? Thanks

 

Check the price of those bearings before you cut it off!

Attached pic is how I removed my outer bearing - but as I said, the inner one just slid off with no dramas.

Just to check, you havn't got something else impeding the removal of the bell housing per chance? Is the clutch on that car cable or hydraulic? Either way, have you disconnected all of that fully?

It will require a VERY special tool to catch the lip on the inner race ...seeing as how the rollers interfere with the clearance.

If I can get the bearing off..is there an additional snap ring behind the bearing? If so...does this ring have to come off to pull the housing? ..or is the ring small enough to fit thru the hole?

Yes, it looks like everything is off and ready to remove the housing. The clutch is hydraulic on this model. Thanks

 

No additional snap ring on mine behind the bearing, just a stepped washer.

The only thing I could think of that's happened is maybe the bearing has got slightly "cocked" to one side & jammed. Maybe if you just tap lightly around the inner race with a small hammer it will straighten up & come off?

Another thought was as to whether you could get a block of dry ice onto the shaft to cool it sufficiently that it would relax its grip on the bearing - but not sure if you could get it cold enough....

 

Good ideas...I will try tham all, thanks.

I was thinking...that if there are no more snap rings...I can pull the housing all the way out until it touches the bearing and spacer....and then use the housing to bang against the backside and walk it out ...well in theory anyhoo

 

Thanks for you input so far Iain

I had a thought

If you needed a puller to remove the outer bearing ( as pictured in your post above) because it was so tight on the shaft......how were you able to remove the inner bearing?

Wasn't the inner bearing just a tight? Tell me the tricks as I am still struggling with this.

I was able to use a small mirror and look at the inside opf the case...I think I saw the bearing and spacer but no additional snap ring...it appears to be just as you described.

My parts catalogue shows a snap ring there but it is for a 1984 3.2 , so maybe they changed it in production? (mine is a 1986 Mondial)

The posts on this forum show a snap ring there but these tutorials are for the 308...not the Mondial

Thanks again, Tony

 

Do not bang the case against the bearing, cast aluminum is very fragile. Call me Monday I will walk you through it.

 

Grabbing the bearing like showen in that pic is very risky. That bearing is EXPENSIVE!!

 

In that case there was no other way to get it off. Some of the lower gears I've seen pictures of (see below) have three threaded holes in them to screw the legs of a puller into to pull the gear and the bearing in one - mine doesn't have them and there is no way to get the claws of a puller round the outside of the gear either, so I had to pull the bearing off like that.

Once the bearing was off the gear slid straight off without issue.

The inner bearing on mine was not tight on the shaft at all & I was able to walk it out with the bellhousing as described in Birdman's 308 clutch tutorial thing.

(hence why I think yours has got jammed somehow).

Any progress?
