350 diesel starting

jcwag · Sep 20, 2010

got the 350 diesel home, played with it a little but cant get it to start. pump has fuel, but dosnt seem to be pushing much out. i know on my jd 2520 if i remove one of the lines at the pump, the pump will squirt fuel out a few inches, but on this 350 it wont squirt at all just dribbles out so i dont think it has enough pressure to even open the injectors. i held a paper towel a inch from the port and it dosnt get wet. any input would be welcome. also how important is the pre heater? it isnt working from what i can tell and was about 65 degrees out. thanks for any input!!

The preheater is important, but insufficient for starting when chilly. (the neighbor that purchased a 350U at the same time we purchased an identical gas powered U, had a can of ether in the tool box for every cold start at all temps. He still has the tractor, and (I am not suggesting the use)it has had two rebuilds in its life.
I would pull start the tractor for a half mile. If it will not start, and there is no whitee smoke, it is fuel related. If there is copious white smoke, Look to compression issues.
Be careful pulling a tractor. Be sure of your communication with the pulling person and the vehivcle they are operating. Do not exceed the ground speed in any gear, that that gear would produce. 4th gear in direct drive at 5 MPH is reasonable. Jim

I had the same problem on a Case 830 I was working on. Then I figured out that I had forgot to have the throttle advanced. Sometimes you forget the most basic things. Good luck.

Preheat is important- quite right even in warm weather. Instead of ether a shot of gasoline in air cleaner or intake is safer, propane also helps. Injector pumps last fairly long but they do wear out and need rebuilds- mine was done with block exchange. Filter fittings need checking- loose line should leak enough to be seen but check top nut one last turn. Geat the preheater fixed- switchs/relay/wire check as well as heating element in manifold. RN

Is the heating element available? My 350 Utility Diesel is indeed a cold-blooded critter

jc,

The fact you have fuel to the pump and not
thru it would lead you to think that either
the metering valve or the pumping plungers
are stuck. The metering valve is accessible
with out complete tear down of the pump.
I have had a rash of stuck metering valves
this year in the pumps that come in for repair.
