My engine guy is asking what kind of clearance I want my rebuilt Cat 10 engine to have for the Rod and Main Bearings, We were thinking .004 is this Correct?

Thanks Steve

I don,t have any specs. on your engine but starting engines in the sheet I have shows the rods to be about the minimum what you listed & mains a couple thousands more (.006") minimum. I,m sure someone on here would have the correct specs.in a book but the ones I gave is a general clearance to go by.

Hi Steve,
my 10 Tractor Serviceman's Book tells me clearance for both the main and bigend is 0.003". The Pony engine equivalent half of a 10 tractor engine, as SJ pointed out, is 0.002"-- 0.004"" for the bigends, and 0.005"--0.0085" for the mains.
I feel your reco man's thought of 0.004" for both main and bigend is a good compromise and what I would aim for if it were my machine.
I feel the pony main clearance is opened up to accomadate the 2850 high idle RPM of the pony against the 1500 RPM of the 10 Tractor engine.
Hope this helps,
Cheers Eddie B.
