Thread: choosing bearings

right i want to drop a RR 2.0 crank in my 16ve..

so if i take the numbers off the crank :-



then take the numbers of the block



and run them through here..



i should end up with the right sizes..

so going on this pics if i were using this engine with that crank shown i would need :-

34343 bearing sizes.. (editeddue to me being a numpty)

is this correct? if so why isnt there a thread with this info on i couldnt find one

Mains #s on crank are 23222

Mains #s on block are 11121


So the bearings #s you need to get are 34343

ahh **** yeah sorry added them up wrong.. should have written tham out like you did rather than flicking from pic to picture.. ill edit to save dis informatoin..

forgive my stupidity but where does the 34343 fall into the chart you posted?

Please take a look at that chart and ask the question again. It is as clear as day.

Uhhh... Is this a RR only thing or?

I replaced my main bearings using just the numbers on the crank. Is this a problem?
Do you take both numbers into account only when you install a crank from a different motor?

I'm starting to feel like the FSM let me down in this area.
I'm starting to think I'm fuсked.

as far as im aware its on all nissans.. thats why i got confused some people say crank some say block.. but when you look at the chart you need both.. and there isnt a clear thread about it.. well untill now..

This is for all SR motors

Yep you have a problem

Nope, this is done with all crank and rods, both number must be used/

dre is there a second number stamped on the rod aswell? i know there is a number stamped next to each bore on the deck.. but this is piston grade isnt it?

Yes there is.

There are numbers that tell you which hole the rod came out of and there are numbers that tell you what size the bearing hole is. You have to follow the same thing to do the rods.

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 ).
