Melling M54D oil pump
I just took apart a Melling oil pump to see if there were any issues before putting it into my new 463. I think you can see from the photo that the gear teeth have some striations along the leading edges, especially on the driven gear. Is this a problem that would effect the efficiency of the pump? There is also some wear on the cover where the gears make contact. I assume this is normal.

It's common to see that stuff, regardless of brand. Problem running it? Not that I have seen. Just looks ugly.

I would sand the scratches out of the cover on some soapy wet or dry 220 grit sand paper in a figure 8 motion and put it back together with blue Loctite after all the oil is off the bolts and out of the bolt holes and running it again!

Yea, I will clean it up and run it again. That is what I was hoping for, not to have to replace it if not needed. Thanks.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
