FD620D

[Jheald65]

Hey folks , just joined and looking for some advice , I’m brand new to Kawasaki engines , but have always tinkered with all kinds of engines ...
I picked up some one else’s problem, a Mule with a FD620D engine ..
“Someone “ had taken the engine apart to the point of finding the broken cam gear and then abandoned the project. I have it all apart and have cleaned up the case and all other parts . Now I’m at the reassembly phase and having some questions.
It appears that the govenor stud is “missing “ it doesn’t appear that it has broken , actually looks almost factory to not be there . And I don’t see a place for the govenor rod to pass through to actuate a govenor if it were there . Where there other means of rpm control that was used?
I don’t know the year of the mule or the engine

A Model would HELP! Can you find a tag on the Mule, not engine, with a model number? It might be, for example: KAF 620 A4
Did you find any linkage parts for the governor? IIRC the governor shaft will be in the other half of the crankcase, end coming out between the cylinders. Kind of hockey stick shape. 39003 that a lever mounts to.

Yes sorry I didn’t realize that I hadn’t put that in the original post it IS KAF620A

This is how it was when I picked it up

Interesting your KD620D engine does not have the electrical heater fitting on the carb. I am guessing that makes it 20yo or more.

I am currently working on a JD Gator 6x4 with the same engine. Someone worked on it before, and really screwed it up. I cannot tell the model year on mine as the VIN is missing. Prob about 15yo. The mechanical choke is not used, tho it is still there. Will need full carb rebuild...amazing how small it is....

I’m sure , I don’t know anything about it except for the stud where the govenor is supposed to go , isn’t there lol.. I did read somewhere that at some point the switched to a transmission style of govenor? Anyone confirm that ?

It may be in the transmission. Where does the rod (left end as pictured, red circle) connect P/N 49103/ A/B? I think this is the governor linkage P/N 16171A/B
