con rod bearing, which Grade ??

[Eric Yellow]

I've been looking at the FAST thingy from Nissan, but there are only things like Grade 0, Grade 1 and Grade 2 part numbers...

There is nothing from which I can see what size the crankshaft diameter shoud be for the Grade 0, 1 or 2.
Is there aynone who can tell me what size the Grade 0, 1 and 2 mean ??

The manual show that the bearing grades should be stamped on the crankshaft, either front or rear. If there's 5 numbers it's the main journal grades, 4 numbers are the pin journal grades.

Hmm....are you telling me that the only way I can see these numbers is if I take the crankshaft out ??? (if they are on the fornt or rear..)
I do see some numbers on the crackshaft, but not on the front or the rear, I see them on the side of a counterweight..
These numbers are: 604J0 and 65-0
Are these any good ?
If so, what do they mean then...?

Yes, sorry, it's on one of the counter weight as viewed from front or rear ends.
I knew I'd posted it somewhere before
