No, It does not work on the MG XPAG etc. clutch due to the geometry of the clutch lever / release mechanism which does not keep the bearing parallel to the drive shaft and clutch bearing face.

Hi All,

Big print for old guys.

Barry, I would NOT touch that roller bearing with a barge pole. It is a BAD idea as the roller bearing pivots on the clutch fork and so does not remain in direct straight on contact with the clutch cover. It moves through an arc and so becomes side loaded in use. A friend tried a roller several years ago and it only lasted a short while before it failed.

 

The carbon thrust can accommodate the off-set as it goes through the arc. In 66 years of T Type ownership, I have never had a carbon thrust fail and have to be replaced . However, make SURE you have a return spring on the clutch pedal so the carbon thrust is clear when driving. And don t ride the clutch when driving. I shift to neutral at extended stop lights and take my foot off the clutch to save wear on the carbon thrust. .

 

Earlier MG MMM cars use a roller bearing but the bearing remained in straight on contact as the roller was located around the first motion shaft and vertical movement was accommodated by the clutch fork. Different design from the T Type.

 

Believe it or not, the MG Boys knew what they were doing.

 

But as always, your car, your money, your decision.

Hi All,

I noticed on Ebay a fellow has a modified clutch/pressure plate release bearing having replace the carbon with a real bearing.  Sounds like a good idea for the sake of longevity, but I like to hear any opinion, or better, long time experiences with this bearing.  At 10 times the cost, it would seem to be worth it when taking in consideration the effort removing the tranny, and or, the engine getting to this bugger.  But then again, if the carbon bearing wears out about as fast as the clutch disc, then it would not be worth it ???

Any ideas, before I plunk down any money for this unit ???

 

Thank You All,

When I let the clutch out on TC8110 with car out of gear I hear a  continuous but light scrapping noise like the release bearing in in contact with clutch tabs - but when I push it in the noise goes away - clutch does not slip when moving or starting to move - any ideas or has anyone seen or in reality heard this -Thank youJames LeeMontana Sent from my iPhone

Make sure there is a return spring on the clutch lever to be SURE the release bearing is fully clear of the clutch.

I'll check it - might not hear it when I'm in gear and going - don't want to wear it out any faster than necessary - not sure if spring or not - should be easy to see Thank youJames Lee Sent from my iPhone
