Title: A10 Small crank journal Specs ?.
Post by: Josh Cox on 05.07. 2009 15:21
Am working from the Haynes book which does not mention the small crank journal specs.

What are the specs for the big end OD for the journal ?.

Thanks in advance.

It just so happens I have BSA service sheet 207 on my desk.

Part Numbers 67-384 and 67-664 - [check yours is one of those].

First regrind, [therefore 0.010 under standard] is 1.4500/1.4495 with a 0.090/0.085 radius.
