Had the tractor regularly serviced since purchased. Notice the tractor sounded like it was missing and found the old
injector pump was leaking so I had it rebuilt twice a year ago. After the first rebuild I started the tractor and it ran
(idled) for a couple minutes before noticing an issue. The technician did not put shaft seal in right and diesel dumped
into the oil pan. Had the injector rebuilt again by professional service the second time using metal parts instead of
standard plastic. Still had missing issue so I had the injectors rebuilt this past fall. Now it smokes (white/blue) and
clatters when throttling up or governor kicks in. Power seems sluggish when under load.
Follow up:
The injector is an updated on Stanadyne Roosa pump that appears to be for a 4020.
The previous owner said the tractor was one of the last 4010 tractors manufactured and a 4020 engine was factory
installed.
I have been unable to verify even by going through John Deere.
The only thing I do know is the timing is set at top dead center "0" and not 14 degrees before like a typical 4010.
The first pump rebuild was by a technician my local John Deere dealer recommended. When I reinstalled the pump and
started it and let it idle, the oil light came on and I shut it down immediately smelt diesel on the dipstick and drained
the oil pan to find diesel had dumped from the injector. I decided to bite the bullet and had both the pump checked out
and repaired by Thompson's Diesel in Oklahoma City which was not cheap. I also had them to rebuild the injectors last
fall. I put everything together as per shop manual and bled the lines once started. I bled them again checking to make
sure all cylinders were firing but still have a clatter upon starting out or when governor kicks in.
