Renault R4 connecting rods

[Richard d]

Good morning,

I do not know if you can help me. I have a 1964 Renault R4 fitted with the 845cc Billan court motor. I am looking to have the connecting rods machined to std. The connecting rod has a 16mm gudgeon pin, what I can not find is the original big end bearing tunnel size, or another set of conrods.

Can you assist me, ore point me in the right direction.

Thank you,

Richard.

Are the early conrods white metalled and you need to know the standard size for machining the big end bearing? What's the engine type? 800-01 would be 845cc. 680 - xx would be 747cc. With the engine type someone with an old book ought to be able to find the spec.
