Bosch Pump oliver 77, 88 diesel

A friend working on an Allis WD45 Diesel. Pump bad, was told Oliver used same pump on 77 and 88. Is this true and does anyone here have one for sale.
Closer to NC the better. TKS

The early PSB pumps use a spline drive hub, later use the tapered shaft/key hub/shaft drive. Oliver had the external governor linkage on opposite side than AC did. The Cockshutt 40 PSB pump is a better choice to look for.

Thank you Dieseltech. Does anyone reading this out there have or knows where to look for this pump? TIA

I have a newly rebuilt PSB pump from a 570 with 298 engine, but is likely different than the Cockshutt 40 PSB.

The WD45 used a 7.5 mm diameter plunger and the Olivers used an 8.0 mm diameter plunger.
And the Olivers used a mechanical supply pump driven off the engine camshaft, while the AC’s used a gear driven supply pump mounted on the PSB pump. But the pumps were basically the same otherwise.

Wrong, Oliver 66, 77, 88 all used 7 MM PSB heads. Massey Harris used 8 and 10 MM heads.

That's good to know. Now I have some reference.

Yes, you are right. Typo on my part.
