just wondering if anyone with FJT custom length i beams had a tight clearance on their rod bearings?

mine are a tad tight.

how can you get a smaller bearing? is it ok to mix and match OEM with ACL (i would guess no because they are different design)

i had problems getting the rod caps off so i think my readings might be a bit out.

just wondering if anyone else had a similar reading. (couldnt imagine my crank growing... lol)

Yes, you can mix and match bearings as long as each of them are in spec. The ACL's are suppose to be similar to "Green" sized bearings.

The dealership should have what you're looking for.

from what i remember min clearance was 0.0008-0.0015. and my green plastigage kit's most specific measurement was exactly .001. and when i checked the width of the plastic strip (after torquing down of course) it was slightly wider than the widest strip on my plastigage reference piece. so, its tighter than 0.001.

so my guess is somewhere around .0008... i need better tools to know for sure.
