2 ways to do it.

1) plastigauge with old bearing and find out
2) http://img.photobucket.com/albums/v210/partsforsale/94723860.gifthen plastigauge again to be sure.

If the OP is asking this question, then he probably has no idea what you're talking about.

Plastigage is the cheap and easy way to go. It works just fine if your not building some high horsepower track engine that you want to be 100% perfect, but I'd rather know my clearances regardless of the purpose of the engine.

Read up on Plastigage, and understand how it is used before using it. I'm sure it will do you just fine.

I think he was meaning like .10, .50 oversized bearings etc. But yeah, Honda is the only company with color-coded bearings. The only way to get the exact clearances and corresponding color codes is to plasti-gauge. If you are going with aftermarket bearings like ACL or something. Just use the standard size bearings if you haven't had the crank turned or anything. Still check your clearances with the plasti-gauge though.

yeah thats what i was trying to ask...i know about plastigauge though. so standard sized acl bearings will work since my crank has never been turned or anything...should i get the crank turned or anything?
