Does anybody know the exact sizes for each of the bearing color halves?

Thinner
Pink -
Yellow -
Green -
Brown -
Black -
Blue -
Thicker

I'm mic'ing the journals and bores in anticipation of using ACL bearings. I have 2 blacks and 2 browns and 1 green that I removed from the caps...so I'd like to know if the ACL's are gonna work or if I'm gonna have to use oversized ACL's to compensate for the black's and brown's lager size and wear & tear.

I don't want loose tolerances b/c I'm not looking to rebuild the engine for a long time, so I wanna build it within safe tolerances and keep the clearances in the middle of the range (around .0017" to .0018" is what I'm shooting for).

I've heard that the ACL's std sized bearings come in yellow/green Honda size, so I'd like to see where I stand.

Yes I do know that I should use OEM Honda bearings if I wanna be **** about the clearances, but teh backorder and price are what's holding me back.

Thanks

I'm already talking to Rocket about buying the ACL bearings. I'm just waiting for him to get back to me.

 

ACL bearings match to the green size code.

 

I guess my tolerances are gonna be too loose then with the standard-sized ACL's...either that or borderline to the service limit.

How much bigger are the over-sized ACL's? Are they 25/1000th's (.0025") over?

 

not .0025 but .025 on the acls oversized. Not what you are looking for

 

It's 0.25mm or 0.010 inches for the 1st over size.

ACL rock! Anybody running 9's or slower should run them.

 

Correct, ACL's can be bought in standard, .25mm, .50mm and .75mm oversized. For our metric impared friends that's very close to .010, .020 and .030 in inches (NOT .001, .002, .003). These sizes are for reground cranks and not for bearing fitments.
ACL standard size work with all stock Honda set-ups and will put your rebuild within all specifications. Work great with Eagles, Crowers, etc.
