If your splitting the cases then it worth overhauling the crank, measure and order new bearings. Have a look at Pyndons info page, ISTR the newer case has a locking plate for shells.

I got the idea from one Pydons (I think) posts where he had cam cain rattle and the spring and plunger solved it. If this doesn't work Ill do the tensions though.



Has anyone replaced crank bearings without the press tool? Hopefully I will be able to get that apart and spec'd out today or tomorrow.

I am going to try and do the carrier bearing without the tool, but the mains worry me about damaging the cases.

The wear on the carrier bearing is really odd looking, I don't understand how that could have been done unless the crank is not square, but then it seems there would be a lot of other issues. Maybe the bearing got cocked??
