Dear all, I need info of the bearings for the engine (comercial name or size). I have an old engine to repair but is without bearings...so I do not know what to buy. Please help me. Thanks Devis.

Hi Devis, Ian has put this on the technical page.

Thanks, just a question regarding the timing side lipped roller MRJA7/8 bearing...I need 2 pcs? right?

Hi Devis...The roller bearings are made up of 2 pieces..an inner with the rollers and cage and an outer ring. Both pieces will be supplied under the one bearing number (they come as a complete set).
You may have trouble finding them all in a 'C3' fit but don't worry...standard fit bearings seem to run OK...but buy good quality European or Japanese bearings.
Also when I put that information in the 'Technical Section' I didn't list one bearing...the timing side ball bearing. The M20 has 2 bearings on each side of the crank. I will get Henk to add that tomorrow if possible. (I think it is an RMS7 but I will have to check)...Ian
