My list of Yanmar Tractor Engs. are from 1975-1992 in the FX Ser. and 3TN84 is the closest I come.

Ask at a diesel injection rebuild shop

Sometimes the only difference in Yanmar injection pumps with different part numbers is the little riveted badge that has the engine model number stamped on it. Everything else is the exact same. That being said I have not found anything indicating that the two pumps you listed would interchange.

. Thanks for taking the time to check this out for me.
Looking at the pics. And comparing it to the one on my tractor they look the same,it is new comes with lift pump and shut off sol.for around $200. My old one has 750 hrs.it works good but is leaking fuel into the crankcase.I may pull mine and have it fixed.

Did you try to cross reference the two numbers on the Deere parts site? Are the numbers below Yanmar numbers? Do you know the JD numbers?

719923-51470 and 729223-51480

. I haven't cross referenced on the Deere parts site.
Numbers are Yanmar from the tag on the pumps I'll look up my JD # for my pump tomorrow in my manuel ,as for the 51480# I have no way of knowing. Any help is greatly appreciated. Thanks
