Small Dozer Trouble Starting Hot

Long-story short: we have a 1980-ish Case 350 dozer with a rebuilt engine and a replaced rear end. It normally starts in weather above 50 deg F no problem if the batteries are fully charged. After running the dozer for 1-2 hours, it struggles to start. Seems to have plenty of juice, but the engine won't fire. Of course, eventually the batteries quit. Letting it cool down seems to solve the problem. Is this likely a fuel issue? We have had a clogged fuel filter in the past.

I would check for trash being sucked into the supply line going to the transfer pump. Take the line loose and blow back thru it with compressed air, you probably have trash in the fuel tank.
 
What injection pump does it have? The problem you are having sounds very much like a Stanadyne pump with a worn head and rotor. (Or similar rotary IP.)

Next time it won"t start, poor a bucket of cool water over the IP, wait a few minutes for temps to even out through the pump, then see if it starts.

(Do NOT poor water on the pump while it"s running or cranking!)
 
Thanks for the suggestions, we will try both next time I run it. Not sure of the pump, will have to check the service manual.
 
I assume you've got a Case 188 or 207 diesel with the Stanadyne rotary-distributor pump. What you describe is a common problem when the distributor-section is worn out (head & rotor). Very common problem in the US military with GM 6.5 liter engines. If you pour cool water on the pump and it then starts - that's your problem. One other possibility is low fuel delivery due to the roller to roller adjustment. Does it make normal full power when you run it?
