Can anyone post the journal size for a 383 crank. I have this one looks nice and clean . I only have a digital caliper to check this, but it only reads 2 decimal points.

Just wondering if this is standard or has been turned some.

Thanks for any help
 
Rod journal size , 2.3740" - 2.3750"
Main journal size, 2.6245" - 2.6255"
These are for a "standard" size.

Harbor freight has a digital caliper that reads three digits, for about ten bucks. (Or, at least they did have, before the 20% coupons went away.)
You are trying to measure something where a thou or two is critical, with a tool that only reads to a hundredth?

Well ya, LOL. that's all I have to work with. :BangHead:

I was just trying to check it. Guess I need better tools !

A set of mics would be ideal, but a good dial caliper is one of the most valuable tools you can get. Measures inside, outside, and depth. Digital, with three or four digit resolution can do it too, but i prefer my analog dial. (I do have a digital, but i find the battery dead quite often when i try to use it.)

I used to have a nice set of Mics but didn't use them for years, eyes have gone south , even with glasses and couldn't read them anymore. Guess I make a trip to HF. SO you think this crank could be STD ?

I do.
Edit: my eyes are crap too (eight surgical procedures), but i had my eye surgeon put in nearsighted lenses when i had my cataracts done. My close-up vision isnt bad, but when i REALLY need to see something...... i use a set of cheap plastic eye loops from (wait for it) harbor freight. Set of five was two bucks? Less than five, for sure.

I wouldn't trust verniers, even if they measure to three decimal points for measuring cam, rod, main brgs; or pistons/bores. When I have compared measurements taken with digital verniers/calipers & then with a micrometer, the numbers are different.
