i picked one up last week...where is the governor?....

 

[winston1]

right here: GOVERNOR: Yanmar Tractor Parts

 

[ghitch75]

thanks for the link!!!.....i guess i need a service manual to see how to adjust it....

 

[winston1]

What is the governor doing or not doing? Could be the rack on you injection pump sticking.

I don't think the governor should ever need adjustment. If something is sticking - was the tractor parked for a long time? Simply operating it might loosen up sticking.

As Winston asked, what is it doing? I don't recall that anyone with a YM240 (or similar) has ever posted here about adjusting the governor.

i don't know how long it has sat i bought it as a trade in at a Kubota dealer ship....it doesn't blow any smoke blue or black


it just acts as it bogs when you rev it up and it doesn't seem to blow much black smoke under load.....i'm just going from the backhoe and dozer that i have....

is there a place to check the rack without pulling the pump?

Fuel Filter is what it sounds like. I would Replace that first and cheap at napa Part #3262..

You can pull the inspection plate off right above the injection pump to access where the governor attaches to the pump rack.

It should smoke and hold rpm under load in the same manner those, maybe not so severely. But I suspect it may loosen up after a little use. What you described is unusual.

That's the first place I'd check too. It could be that the governor is working fine and the fuel flow is restricted. That would match the symptoms. Good call.
