TO bearing, pressure plate- noise and grooves (no dancing)

#1 Post by Harold Singh »

Not the kind of groove you dance to normally!

Hopefully the album link works. Looks like the TO bearing is in good shape but one ear is more flat and I think my noise may have been the adjustment since it seems the PP was touching in more places than normal. I think the PP is in need of replacement now. Any thoughts?

The grooves on the pressure plate fingers are the result of normal wear and tear after many many clutch operations. Holding the clutch down while waiting for the lights to change will definitely exacerbate that kind of wear. That is why in Europe we were always taught to stop and engage the handbrake and take the car out of gear if one was expecting to stay stationary for any length of time. I still put an automatic into park when stopped out of habit.
The wear on the TO bearing ears bears witness to many hours of being held against the PP as well. Time for a clutch kit and maybe a slight change in driving habits.
If I had known I would live this long I would have pushed the envelope a little harder.

The outer wear ring (about 3" dia) may be from the outer housing of the TO bearing rubbing the fingers, possibly due to the pedal stop not being adjusted low enough to prevent over-travel.

Finally on a laptop to grab the BBforum link for photos in case anyone didn't want to click on the link.

Thanks for the input guys. Unfortunately, I have not been lucky enough to have put all the wear on the clutch. Constant travel for work plus a few 356 gremlins have kept me from driving it much. I don't ride the clutch at the stop lights, I often shift to neutral if it will be long and also never lean on the stick to load the gears. Shift and let go. I'm careful but, this clutch has been in a while based on the part number I read to Aaron at Allzim.

Martin I have been trying to figure that out. I don't see any obvious wear on the TO bearing housing edges on the side that the bearing contacts the PP fingers. I have the 50 mm spec for how far from the bell housing edge but, I wonder if there is something I should be checking for the pedal stop?

If you set the t/o bearing on the pressure plate you will quickly see if the scrapes match up. Maybe they are old marks from a previous throw out bearing that was running.

I currently have a 180mm pressure plate even though I have a “C” car with a 741 trans and shorter “C” T.O. bearing.

Can I install the C 200mm PP and clutch on this flywheel?

No, you would need a different flywheel to fit the larger clutch.

Thanks Martin. So basically I need a B clutch kit with a C TO bearing? Or just the whole B kit?

Aaron at Allzim said he’s looking into it for me but, if someone here knows for sure, I can get my parts shipped sooner!

Easy one. You need a 180 mm diaphragm spring pressure plate without collar and a 180 mm clutch disc and a late T6 style TO bearing.

And the expensive part is the TO bearing.

Wow! I can use a VW clutch and PP?! I had no idea! Have you had good results this way?

Thanks for your help!

There is a very small difference in the clutch disc thickness but under normal driving conditions you will never know. Be aware though that there are two types of clutch disc. One has damper springs and the other one is rigid which makes for a slightly harsher clutch take up. I did hear say a long time ago that American market cars needed the softer take up for American drivers who did not grow up with stick shifts. Could be hearsay of course. I would go for the one with springs as the difference in coast is so small.

Good point. I’ll look for that but, right now I only see 200mm discs with the springs?

http://www2.cip1.com/searchresults.asp?cat=1461

I do see a sprung version on another site here:

http://www.texasaircooled.com/catalog/1 ... 62-65.html

I assume this would also work?

Thanks

I have found that you can hardly tell if there are springs or not in the disk center, they all drive about the same. I think it takes some figuring as to what parts will mate to put a VW clutch in a B or C. The flywheel depth is a bit different, and the t/o bearing is very different. Maybe someone know exactly what fits.
