c20let crank bearing size

[jonn]

i am rebuilding my let and trying to figure out if my crank has been reground which i think it is.

i measured the crank main journal with a micrometre and i am getting 57.760.
this is what it should be below. mains, 57.982-57.995mm std
the bearing just says GM 15 665-A at the top and 1202AK at the bottom.

how can i find out what bearings size i will need?
THANKS

He's not guessing he's measured it with a micrometer lol

I think they're reground in .25 increments if that helps?

[jonn]

ok i will bring it in and get my local mechanic to check it. better to be safe than sorry!

[swedge]

Yeah .25 increments I took mine to get checked an okay needed a polish

Use td bearings though they are the same size cheaper and more heavy duty
