Oliver 1750 Roosa master parts

[snappy2l]

I have an old, not sure what year, but probably late 60s or early 70s Oliver tractor with a Roosa Master fuel injection pump. I love this tractor, but recently a plastic t fitting above the pump on the front of the engine head cracked and is leaking fuel - Badly. I removed the cracked T-fitting and it has Roosa Master on the fitting. The T fitting is 3/16 inch left and right with about a 3/8 fitting on the bottom to accommodate what looks like a check valve (I am not sure about this) coming out of the top of the manifold. Does anyone know where I can find parts for this tractor, specifically the one that I am looking for?

Snappy - Here's a few suggestions:

1 - Try first at your local diesel pump shop. The Roosa distributor pump on your Oliver was used on engines by several other diesel builders of the era (Allis-Chalmers, Minneapolis-Moline, IHC, etc) .

2 - Visit the local John Deere equipment dealer. The same Roosa pump was used on the venerable 4020D and its many descendents. It also found application some JD construction machinery and stationary power units.

3 - The Caterpillar dealer. The Roosa was used on some Perkins-manufactured diesels marketed by Cat.

Good luck - the Oliver 1750 is peerhaps one of the best tractors ever built!
