Acl Bearings, Std Size -- No Grades?

[Stronzo]

hi,

I know that many people in AU use ACL bearings. But ACL makes sets of bearings of STD size only -- instead of several grades for STD crank which Nissan engine manual recommends.

Nissan has 3 grades for standard size crank conrod bearings (STD0,1,2) and more -- for main bearings (5 grade for rb25 and 7 grades for rb26). The selection of bearings is made based on the numbers printed on the crank, block and conrods.

For example -- Power Enterprize "Black Metal" bearings have this grades too. But ACL -- no grades... Or i don`t know how to order it right.

Is it possible to make such a selection with ACL bearings? If no -- then how is it possible to make the right oil clearances in bearings?

Thx.

I'm interested in this too.

Cubes Recommends King Bearings, made in Israel.

You don't have to ACL, and when it comes to bearings, you don't skimp on them, even if you're on a budget.

The ACL bearings are all standard grade like a few others and you will need to get the engine builder to machine your crank and stuff to get the desired clearances

what happens if the crank is to far out of spec? or does this rarely happen?
