My crank journals is bigger than whats in the bearing catalog

[MidShipCivic]

I have on almost every journal .

Rod 1.796''

Main 2.269''


In the ACL catalog is says shaft for rod Min - 1.7713 / Max -1.7717
For main it says Min- 2.2433 / Max 2.2441

? I measured countless times to check if I was off this doesn't make sense.

Try a different micrometer.

Notice that you are consistently off by 2/100ths of an inch? I second trying another micrometer or checking the calibration on yours.

To measure a 2'' journal I can only use my new 2-3'' micrometer.

For the rod the 1-2'' is the only one I can use.

What brand of micrometer do you have?

Well I'm not sure but I have the same ones at school.



It's zeroed out on the 2'' bar. (blurry)

Everybody hates it when people say that. Would you mind explaining what the problem was in case somebody else has a similar issue in the future?

I was using the micrometer wrong, plain and simple.
