My original outer oil pump rotor is cracked. The inner looks fine. There is a small amount of scoring on the inside of the surfaces where the rotors sit. You can see the scoring but you can't feel it, if that makes any sense.
I bought a new rotor and assembled it all and installed it in the cover. I put a tiny amount of lubricant on all the rotor parts and the housing. Seemed right. I can spin it by hand it moves freely.
If I tighten the 3 Phillips screws snugly, the rotor will not turn. Leave them loose and around it goes.
I measured the original rotors - inner is 8.00mm thick, the outer is 8.01mm. This on my budget digital micrometer. The new outer rotor is 8.09mm. Is this the problem? Or is there supposed to be a gasket between the oil pump housing and the side cover? I don't remember one, but it was awhile ago.
Educate me please. I can't seem to find an exploded diagram of these parts.
Thank you.
