I was wondering if my b18 b crank is within spec

crank mains
1) 2.1647
2) 2.1646
3) 2.1642
4) 2.1647
5) 2.1648
crank rod
1) 1.7958
2) 1.7956
3) 1.7955
4) 1.7957
these are the measurements I got using my micrometer. This is the first time I’m doing this. Does anyone know if it is within spec? I bought the acl race bearings for my build. I will be micing the block soon I will post up with that too when I do it.

 

Did you use a ball micrometer or attachment to your micrometer?

Do you not have the FSM for the CRV. It will have Honbda spec for the B18B, I think the 97 CRV is the B18?

 

No ball micrometer I used this set I bought on amazon. And also what is a fsm is that a manual for the b18? if so I do not have. Are these micrometers not good for measurement on a crank

 

Sorry, I was thinking about measuring the bearings. Your micrometers are just fine for the journals of the crank.

FSM is Factory Service Manual. In particular the Helms manual which can be purchased reasonably at helminc.com or can be had for free with a good google search. Many of the links have been pulled but still can be found.

I think you want the 97 crv maybe the 98. I don't know what generation that would be but I believe they used the B18B everyone grabs. I could be mistaken and it's an acura integra motor.

Yep I was mistaken older Integra motor:
