Title: Con rod & Big/Little end assy wanted
Post by: PaulG on 21 November, 2021, 05:51:58

Hi All,

Where could I buy a new con rod assembly for my '53 D1 ?

The gudgeon pin I have in my new piston (re-bore) is 12mm. The old one in the damaged piston was also 12mm.
Apparently some early D1's had a smaller gudgeon pin.

The big end pin that I pressed out of the flywheel is 19mm (or 3/4")

See photo.

Thanks in anticipation,
Paul G
