Clutch roller release bearing Austin Healey Sprite MG Midget MGA MG TC TD TF ZA
Sprites, MG Midgets and MGA, MG T-Series all use clutch release “bearings” which in fact aren’t a bearing at all but have a carbon face. The carbon used in the modern reproduction units is nowhere as strong or dense as that used 40 to 50 years ago when the cars were new. The modern release “bearings” have a very short life. The shortest life-span that I know of was six weeks. It took just six weeks to turn what looked like a perfectly good new carbon “bearing” into a pile of dust in the bell-housing. The owner was not pleased having to pay the mechanic to remove the engine again. STOP PRESS: There is a new record. From brand new carbon thrust “bearing” to broken chunks of carbon in the bell housing after qualifying and three races on the Saturday of a two day race meeting. The customer missed all four Sunday races and had to pull his engine out – again! Since there is no commercially available roller release bearing available, I started making my own in year 2010. I use the original cast iron carrier, suitably modified on my lathe to accept a high grade fully sealed roller bearing, into which is pressed a nitrided steel sleeve with a baked-on Teflon front face. The Teflon coating was designed by Cosworth for use on Formula 1 engine pistons. These roller release bearings will outlast many carbon ones, and are essential if you’ve upgraded to a heavy duty pressure plate. Of course you can continue to use your old carbon style “bearing” if you really get your jollies out of removing and replacing engines to get to the thrust bearing! I make the release bearing with different offsets to suit the different model cars. Just tell me which one you need. The 948cc version will also fit Hillman Imp. I can also supply a roller release bearing to suit MGB, and since it’s commercially manufactured not hand-made, it’s quite a bit cheaper. I have now fitted it along with a NOS pressure plate and driven plate. It has turned out even better than I expected, with a light action, making gear shifting much smoother. When viewed through the inspection hole in the bellhousing, the bearing runs beautifully true on the pressure pad. I have recommended you to a couple of the guys in our club (Midget and Sprite club) who have been looking at alternatives to the dreaded carbon thrust, so you may be getting some more orders. You are doing a great job with that fine roller bearing for the MGA. I tell people that and you can quote me. All running great put some miles on the new bearing and runs and shifts great!
