Oil Pump Crank Collar

[leg46y]

I had my N1 oil pump fail on me the other day, i had the crank collar machined on

when i had that oil pump fitted.

Now im wanting to upgrade to a jun unit but im unsure if the jun oil pump will fit onto

the N1 collar?

Does anybody know if it will fit, or will i have to get the whole thing done again?

thanx in advance.................

same drive so no stress but find out why pump failed before slapping it back together.

be interesting to know why it died.

I believe the majority of failures are from gears cracking or the backing plate coming loose.

Yeah, the gears broke into many pieces,

i dont think that they respond well to high revs, anything near/over 7.5 rpms with

some decent power (over 350rwkw) and i was told that thev got no chance.

but i think high rpms would be the main culprate

Much in the way of bouncing off the rev limiter?

crank looks fine so balancers ok, restrictors and baffles in place.

what else could it be other than a shit pump.?

Although i was told thin oil could also have an impact.

thats the thing. i dont think ive got 1.

i havnt tested out its rev limits but i can tell itll keep going past 7.5

I have to check with my mech.
