Hello all,
My brother in law and I recently purchased 100 acres upstate NY, property came with a few tractors and implements. One was a 63 4010, that the old owner used for his food plots and planting etc, supposedly 3 years ago, I’m thinking more like 6 it stopped being used. Being a car mechanic for 38 years I did get it up and running , fixed a small hydraulic leak , replaced the leaking fuel tank, changed the fuel filters etc.
The running issue from what I found out was a stuck fuel cut in the injector pump. So I decided to rebuild the pump. I did follow the repair manual on removal of the pump, found TDC. Removed the timing window, lined up the marks. Even marked the body and the block for reference.
I watched a video on R&R making sure to keep rotations and all proper. Nothing was actually broken on the pump.
Now my issue. The tractor runs ok on the flat road. But will not tach past 1500 rpm going on any incline on the the property. I haven’t tried any implements. I don’t have another old JD to compare it to. But it seems to run ok, it just tachs rpm rather slowly , smokes a little white smoke . No smoke or pressure out of the pcv tube under the tractor.
I’m pretty sure I have the pump in properly, it starts right up. Just doesn’t seem to tach up as quick as the newer tractor we have. It moves really slow you can hear how slow and low the rpm actually is so I don’t think it’s the new tach.
I did bleed the system of air, I do have fuel going back into the tank from the return. Not sure if an injector is bleeding fuel.
If this was a gas engine I would say I need to crank up the timing, I have zero old diesel tractor experience, but is an engine after all.
Would anyone have any helpful insight as to what could possibly be that I need to tackle or look into.
I totally restored it from the ugly mess it was to shine and new. I’ll try to post a picture
