Yanmar 3QM30 What Manufacturer (tractor) made this Engine?

[AZ-Oldguy]

I have a Yanmar 3QM30 1980 engine. I am told the Injection pump is unavailable through Yanmar, and that mine is not serviceable due to rust. I wonder who made this engine (Perkins maybe) and a source for parts as a tractor engine. I assume that the injection pump, unlike the Manifold or water pump">raw water pump, is not a marinized part, and I hope I can still get rebuild parts, if not whole pump.

I think Y'all can just disregard this post, further research on my own through Google, etc, seem to say that Yanmar (who is a tractor motor company) makes that engine, not just marinize it. And, I have found a place where I can buy a replacement pump that is, I think the right one. 3QM30 (H) (F) - J-Way Enterprises,

Your further help in the event that I am totally misguided here would be appreciated.
