swapping gears

[Fred-R]

i'm wondering if i can swap the internal gears from an N1 oil pump into a standard rb26 pump??

Not sure, never tried it.

I know there's 2x different types of N1 oilpump with different size gears (81mm is early model and 77mm is later model) -

Reimax gears is what you use as an upgrade for N1 oilpump gears that can crack, fail.

yea, i know about the reimax'. But you know, was wondering if the case of the oem would be ok to use the n1 gears/interns... Prolly nobody tried that...

I think housings (where oil flows) are different as well between stock, N1.

Why you ask? Have you been reading this thread -

Would have to have a look at Reimax Japan website, as from what I can remember, it does mention something about it there.

I have a nearly new N1 (about 1000 km on it) but the bottom of the case has been warped off a lil bit. So I was looking for a solution if anyone would need N1 internals to fit in their standard pump for cheaper...

Let me know about waht you can find on reimax site! I might take a look at it too...

the pumps are very different (stock vs n1)

the gear diameters are different, N1 is smaller and has less teeth.

You can't swap anything between the two except maybe the pressure releif valve. I'm not sure what stock is set to but N1 seems to be set at about 105PSI/7 bar.

Just buy a new N1 pump. They're not that expensive.
