Engine bearings

[Draco]

Hi Guys

I am looking to buy engine bearings, I can get ae, engine dinamics and something like toyo, I actually want ndc bearings but are unable to find anyone selling them and I am not interested in importing a set of acl bearings for R2000 because I don't have the money.

Any idea where I can get ndc bearings or even a suggested make that would carry the load?

thanks

Just spoke to Federal Mogal who supplies ae bearings and apparently the bearings for the CA is lead/copper bearings, thus according to what I read should not be a bad bearing, if all attemts fail I will have to use AE.

Bearings are cheap, what size you want?

[Draco]

Measured my crack yesterday and are within the maximum play, the mains that is, the big ends is well within spec.

So I am hgonna use std bearings.

[Gary57]

What number bearings, std comes in 3 sizes...

[Draco]

Thats new to me that the standard size comes in 3 sizes, please explain??

To be honest don't understand, will check the code on the xsisting bearings and post it.

Ok, the crank was machined to balance I presume, there is a bunch of ones stamped into it, so 1+1=2 not a clue what that means. According to what I understand the aftermarket shops only sell one grade(size) standard that is within the allowed limit 0.1mm
Pics if it will tell u guys more than what my brain can make sense of.

Did you have the crank at an engineering place?

[Draco]

Soething like that yes, all the journals are still within std spec.

[Ero_sennin]

Ok thats good, you need to check the numbers stamped on your block and stamped on the crank. You check in the manual as they said how to calculate the bearings you need. You will get something like a colour, green, yellow, etc.. and that is the bearings you have to get. They might not all be the same, so you might need to get different "colour" bearings for each journal. This is for standard Nissan bearings so that tolerances are perfect.

If you get ACL bearings or what ever, just get standard sizes all round.

Cool, understand it that way, will definately go aftermarket and not nissan.

if using aftermarket bearings i would sugest getting some plastiguage at the very least to check clearances.. nissan has like 4 grades inside what aftermarket calls std.. catering for very precise clearance adjustment

[Draco]

Hear what you are saying, not that I know how to use a plastiguage...the thing is it is only std aftermarket size and it falls within the 0.1mm which is the limit according to fsm, so it should be fine, not ideal but fine??
