Cummins bought Onan several years ago. The 1040's are just starting to be liquidated so parts and price are scarce. The 803 is a proven machine, they have been manufactured since 1993. The 1040's started production in 2013. Pro's of the 1040: better fuel economy, a little quieter, digital...

Procedure is in the TM. The shims control timing of the pump. Every engine is different. The shims stay with the pump location, if you have to change pump the shims will remain at the same location. The timing is difficult, because you have to measure the piston height at TDC. Good luck

The 800 series came out in 1993 so 00x series were made till then. I've personally had 00x series that went through tier 2 resets in 2007 so I can confirm up to 2007.

I would give $800 per unit, maybe more if you could send me pictures. If the pumps are damaged that is $800 off the bat, so it's hard to estimate what they are worth.

Never seen one fail. Ive had to clean or adjust a few, even that is uncommon.

Its just the starter. When southern automotive rebuilt those type II starters they used inferior parts which cause failures all the time. I always try to find the old style starters if possible. The type 2 starters usually only last 100 starts and then what your experiences happen.

I saw that, CRAZY. Some low hour 803a generator plant units (2) for $9,000+

If you have little pitting just hone the cylinders and add new rings. I've honed some deep pitting and had great success. Had a 803a with really bad pitting and sold it to a friend and told them if it failed I would replace the motor. That was 5 years and 8,000 hours ago, still going strong.

Little heat around the flywheel plate and jumping on the bearing always works for me.

Need to take the door that covers the lugs off and the center pillar that door attaches to. Then looking at the back of the head, you will see 4 nuts. Take those off and use a jaw puller to push the stator and stator bearing out while lifting on the engine. The engine will come out with the...

I leave the generator head in place and pull the motor. It's alot easier in my opinon. Need to unbolt the radiator support and take everything off in 1 piece. I just finished pulling the motor out of a 813a to put into an 803a. Took about 3 hours to pull it.

Are you sure its oil? Looks like wet stacking coming from the exhaust manifold gasket. Have you been running it with little or no load several hours?

Yes get Light in the Darks door. I don't have one but I've used Light in the darks several times and they fit perfect!

Take a pic. I may have it.

That is cool. Lister Petter LPW4 motor like the 803a. So I would say a 10kw AC unit.

Hard to say. If some fuel had a lot of water in it, it would cause rust quickly. Mainly clogged due to the manufacture process.

Got around to cutting it open. Looks like it was mainly blocked to manufacture process and then rust closed it the rest of the way. It was between the 2nd and 3rd line.

Left hand threads. Opposite of righty tight.

It was blocked somewhere in the middle of the tube. I could not blow air through the end starting at the return line and could not blow air through the 1st 2 rubber lines closest to the return line.

Still don't know what happen. I'm going to cut the line this weekend, in half to see. I tried to blow 120 psi compressed air in the fitting of the return line and could not get air to bypass. I tried each of the rubber hoses that go to the metering pumps and could only get 2 hoses to blow air...
