I have one RHP England MRJA1.1/8 JC2 DRIVE SIDE roller bearing in C2 clearance-- part # 70-2879-- $30 + shipping- this is BRAND NEW NEVER ran and are speck'd as correct for the last years of the 750 twin models -- I installed the outer race, tested to see it was too tight for my 67 650 project, and removed it. This was done by heating the engine case, dropping in the outer races, and reversing the process to remove. Absolutely no damage to this bearing. This bearing has 10 rollers and a STEEL CAGE-- Original box, clean, oiled, as new. What I really need is a Timing Side, 3 piece Metric Roller (C3) for my 79 T140 project. If your interested you can PM me or reply here.

just sold one I had so this may go fast--

Hello man; I have 2 79 engines. In one I installed the C2 and the C3 3 piece bearings; however, the "books" says that for the later is C2 and CN. I have these ones to fit in the rebuild.
I see that you want to use a C3. previous years have the C3 but with balls and seems that C3 balls is not the same as C3 rollers...figure out

I have substantial interference fits for both OD and ID on my timing side hence the C3 is necessary best I can figure-- this is a 73 crank going into a 79 engine case. That is where the departure from the "book" originates. are you interested in my C2 drive side roller?
