1949 B Allis Chalmers
I have the oil pump removed and dis-assembled. The cover is grooved and scarred, as well as the pump rotor. This engine had almost no oil pressure when I tore it down. All the bearing, rod and mains look good. Is this scarring on the oil pump body cover and rotor cause for low oil pressure. If so any ideas for an oil pump rebuild kit or a new oil pump.

Thanks for your help. I am new with AC.

The cover on the right is probly like yours. the cover on the left I re surfaced. The bad one here I cleand up on a surface grinder. When they are not real bad I have cleaned them up with a file until they are as smooth as the one in the picture.

The scaring isn't because of low oil pressure but its the cause of it. It may have bad bushings in the pump or something else. I had an 8N not long ago that had that sort of problem sort of, it would loose prime but once primed it had around 40 PSI. So what I did was took the scored plate and used a flat surface and sanded out the scored areas and it now work just fine. Not sure if you could do that or not since I have never really look at an oil pump in a B/C

Today's Featured Article - Tractor Traction - by Chris Pratt. Our first bout with traction problems came when cultivatin with our Massey-Harris Pony. Up till then, this tractor had been running a corn grinder and pulling a trailer. It had new unfilled rear tires and no wheel weights. The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc ... [Read Article]
