roller bearing conversion (Read 3778 times)

UKTR1 Ex Member	roller bearing conversion 03.05.17 at 16:14:21 I have read a lot about camshafts seizing and since it is not a expensive upgrade I am about to do the roller bearing conversion on my TR1 . I understand that the correct bearing is 6202 but should I use ZZ or 2RS bearings?

But i put in the "open" bearings, no ZZ or 2RS. They have the "normal" clearance, somewhere i read that with a C4 clearance it´s more on the safe side, but as i wrote: no problems,

I currently have 2 engines in bits so would consider doing it too..

UKTR1 Ex Member	Re: roller bearing conversion Reply #5 - 05.05.17 at 15:53:22 I read somewhere that the bearing size is 6202 but I have received these bearings today and they are far too small (unless i'm missing something) The alloy bearing is OD 52mm ID 25 and 20mm wide which makes it a 4205 bearing which is 18mm wide The photo shows a 6202 bearing and the alloy bearing. Am I making a mistake somewhere ?

Ordered 6 x 6205 bearings, I have 3 engines, will do them all. I'll try and do a video instruction too.
