So what happens if you have a block or crank reworked? How does that affect your selections?

Good info btw. Sticky?

I thought there was only 3 grades of rod bearings? Zero, one and two?
You think Nissan makes sure that they never add up to over two?

Then you have to get a little more technical with plastiguage, ( which I use even after using the Nissan FSM method )

or a

Bore guage and measuring calipers

What I gave you was a figure on what needs to be done.


Most all rod combination are 0000 or 1111.

Nissan makes sure to keep the rods and crank journals between 0 to 2.

So when getting cranks from other blocks you have to take into consideration the rods you are using.

I am also sure I have seen a grade 3 rod bearing but I cant remember.

you would need to use a plastiguage or a set of calipers on after market rods as the last set of eagles i had didnt have any markings..

Your crack has the rod jounals as ( 2221 ) so if your rods have ( 1111 ) then your bearings will be ( 3332 ) or lets say your rods are ( 0000 ) then your bearings will be ( 2221 ).

Wrong!! Dre, Dre, Dre ... The only #s used for rods are the ones on the crank itself.

lol, after a lengthy conversation, we will agree to disagree.

GregV is correct. For the rod bearing size just go straight off the crank. No need to go off the chart.

For the main bearing, do exactly as Andreas described. Take the numbers(five digits) off of the crank and block and go to the chart. Read the chart like you are playing bingo or "you sank my battleship".

The confusion about finding the correct rod bearing size come from the number that is stamp on the rod, that number is meant for the small end and not the big end.
