Anyone rebuilding or adjusting the injectors on the 002a or 003a? I have about a dozen I need to get checked or rebuilt.

From your pic, yours is an older model that has an inline glass fuse coming from TB5 6 for the outlet. But I don't see the glass fuse holder in your pic.

I'm blown away! Looks like they never changed the oil in the poor machine. That sludge is from years of neglect. Lots of carb cleaner will get it but I bet it's like tar now. It would be easier to find a replacement before trying to clean that thing out. But I will say I'm impressed for 6800hrs...

Buy Triple Jim's board, best money I every spent. I've purchased a couple over the years for different units with VR problems. So if anyone needs an old board, that is not functioning, I'll let them go at a good price. ;)

You would need to run water in the top hose and have the radiator cap off. You will have a steady stream coming from the thermostat housing. Sounds like the gauge or sending unit is bad if it showed 240 because it shuts down at 220. The TM shows how to test the sending unit. Yes the thermostat...

Sounds like the pump is failing or the filters are clogged. What type of fuel pump do you have? Is it square or cylinder type?

Back to your original question. Only 1 803a. Fermont and Libby made the units to military specs. Onan bought the rights on the motor from Lister Petter to put them in the generators. That is why sometimes you see Onan stickers or lister petter stickers on the motor but Lister Petter is the real...

I'm in West Tn but I have 2 003a's that I need to work on before they are ready. 1,000 hour units. Send me a PM if your interested.

Fastest way is to take the radiator and entire back of the genset loose and pull it as one unit. Then remove the fuel tank so you don't damage. Then remove the bolts on the motor holding it to the frame, take the 4 nuts off the genhead from the lug side and finally use a bearing puller on the...

You don't want to go bigger because 7.5amps is there for a reason. May want to try and replace the breaker with a newer one. I've had a couple of units with weak breakers, that would pop for never reason.

Need to get a picture of the opposite side. The EMI filters are mounted on the inside of the fuel pump mounting bracket.

I agree its the EMI filter on the fuel pump. Follow the wire you disconnected for the pump that tripped the breaker, does it go to a square box or cylinder type contraption before getting to the actual pump? If it does, that is the EMI filter. Cut it out and splice the wires together.

Someone on the big auction site has a NOS Stator if that is the problem..

I disagree with leaks. I've never had oil leaks on any units I've worked on. I've worked on everything from 2hrs to 8,000hrswith no sign of leaks. The biggest issue is the return fuel lines that leak. They don't have oil pan's

Just to give some real life experience. I have a customer running his 802a, approximately 24hours a day, for the past 3 years and just logged 23,000 hours. Items replaced: 2 alternators 1 water pump 1 overtemp switch (thermostatic switch) 2 batteries because one of the cables rubbed against...

Hard to find new but you may find one through Delks Army Surplus. They are really simple and you maybe able to fix the problem if you remove the circuit board from the box and do some testing.

Looks like a good unit. Just be ready to change the returns lines. If its going to be your primary or back up unit, you need to change them because they will leak. Just put fluids in, use the dead crank to move oil around and then start.

Ray, What you described as the conical shaped metal part with a small hole, is the top of the plunger. You do not need to hold the throttle up to see it rotate and move. You should see that turning and going in/out as you rotate the motor by hand. If its stuck us a punch and lightly tap with a...

Gene, Great write up and so happy you joined the site! Like Guyfang said, don't worry about wet stacking with your set-up and load testing monthly. It takes many hours of light loads to have problems. Glad you've been happy with the units. Jimmy Wieber
