John Deere 850 Injector Pump. Trying to source parts for rebuild.

[rayct]

I'm working on a John Deere 850 with Yanmar 3T 80J.

The injector pump has 2 sheared Pin(s), plunger barrel stopping. Part number 103854-51251 .
Does anyone know of an online source for rebuild parts for this Yanmar Fuel Injection Pump?

Part number 4 in the image.



Thanks

Try contacting TBN member pumpguysc.
He is a pump rebuilder in SC.

https://www.tractorbynet.com/forums/members/thepumpguysc/ is who rebuilds them. Excellent references from members in the Yanmar forum.

Hoyetractor.com is a supplier of parts for Yanmars and might have a used replacement pump or a core if you need that. Maybe a new-replica. Deere 850 is the manual transmission version of Yanmar 2500, and they have identical engines, as I recall.

Thanks,
I messaged thepumpguys.

The dealership did not recognize the serial number. It's the badge below the PTO shaft right?

few years back when I did the rebuild on my 950 JD, it ended up being cheaper to buy a generic replacement pump from Hoye. Easier to install and set the timing and just run it. There was a rebuild shop in CA that wanted 2X more money to rebuild the JD pump VS buy a replacement from Hoye.
