throwout bearing too off center?

gregmerritt_type3 · Posted: Mon May 07, 2012 9:01 pm Post subject: throwout bearing too off center?

Gurus,

I mounted a new throwout bearing in my '63 Beetle (with '71 1600), and it sure looks to be a little bit off-center; see attached photo. Is this a problem?

Note that what motivated me to pop the engine out was funky sounds and feel in the clutch pedal; the center retaining ring of the pressure plate was all ground down and loose. Note that the old t/o bearing, as well as the fork, clips, etc. all looked fine.

Hmmmm...now that I look at the picture, does the left fork look bent toward the center? Argh...

Thanks for any advice!

Yes, It does look a little bent inward. No Big Deal

The weld job could have done it IF there are no marks from the
old T.O.brgn. coming off.

Take the clips back off and lube the Saddles and the mainshaft.

Are you sure that's an older style throw out bearing? It's been awhile since I looked at one, but shouldn't the early style have a flat surface where it mates with the pressure plate?

Not to hijack this thread, but is the center ring/collar of the pressure plate supposed to be loose or fixed in the center of the pressure plate? Also, I have the same situation as you did Greg. But my car ended up loosing 1st and reverse gear. I got the same kit as you and hoping it fixes my problem.

Actually, to follow up on that, note that it's unclear to me what the center ring of my pressure plate was rubbing against. My best guess was that the off-center throwout bearing meant that they would rotate non-concentrically and scuff/rub as they turned, and that the t/o bearing is made of harder stuff than the ring on the pressure plate.

Nothing on the t/o bearing, fork, etc. looks worn...

How about some info on Where these parts were purchased?

2 different 200 mm pressure plates
2 different Release bearings

What part #'s do you have?

El Cheapo TO Bearing o,r F&S ?

That is 1 ugly Bearing. Confused

In your first pic it does look a little off to the right side. That would have more to do with how the cross shaft itself was welded and it's bushing in the trans rather than bent arms.

With the original TOB and P/P design, a little off won't do any harm because of the large surface area contact of the centering ring and T/O. With the new design, it may be more critical.

The cross shaft is centered by the bushing and the snap ring on the lever. If there is any wear in them, the shaft can shift to one side. If you want to see if you can center it better, you may have to just take it apart and inspect for wear. The bushing is held by a set screw, and can be shifted to one side or the other slightly before tightening.

You might find some other useful info if you want to wade through this long post re: clutches/TOB's...

Greg, my collar is still in the center. But mine can be moved in & out, up, down, left & right. So its not supposed to do that and should be complete unmovable?

That pic I posted above was the result of a poor quality HD throwout fork that mounted the bearing off centre by 1-2mm with a Kennedy STG1 pressure plate. It lasted approx 6 months of daily driving before destroying itself, the fork has now been replaced with a HD Bugpack unit that centres the bearing correctly
