Yes, DOT 3 will absorb humidity. If you don't change it every two years, it will eventually saturate, then the water will drop out of solution and end up in the lowest spot causing corrosion. DOT 5 is far more resistant to humidity than DOT 3 or 4. Trust me on this, I've been wrenching...

NAPA carries the overhaul kits for wheel cylinders. Since all A2s have silicone brake fluid, corrosion is minimal in every one I have torn down. 30 seconds of honing and they are good as new with new boots, cups and a spring. All 5 pieces are in the kit. The kits are superior to new old...

Poor documentation. On the 002/003, there is a threaded lifting eye stored on the frame near where the jerry can/drum bung adapter is stored. Take the air filter housing off and you will see the hole in the generator case for lifting. The 003A has a lifting bracket on the valve covers for...

Funny how I have pulled all three off, not remembering it is the top center grill boltaua. But I am getting better, yesterday I worked on an H7 classified 002A and only pulled the top bolt. Yes, it ran, after minor fuel leaks and putting enough fuel in the tank. It takes more than 1 gallon...

You have only disconnected the shell from the engine. Now you have to disconnect the flex plate from the engine's flywheel. Take the screen off, two bolt-nuts on the bottom. Now in between the fan blades on the flex plate, you have 6-8 pairs of bolts that need removing. Then the engine...

Check pushrods. All diesels are interference and if the camshaft broke near the drive gear, chances are one or more valves were open causing piston to valve contact. Being a flat head OHV with flat-top pistons, the valves should be fine, the pushrods take the abuse.

Don't think that has not crossed my mind, Jerry! That and using 4-5 electric lawn mowers pulled by it (with a 20 amp 28 volt power supply also driven off the generator) would make it a diesel-electric lawn mower :idea:. Or make a new class of miniature tractor pulling? The diesel-electric...

I'm almost certain the o-rings are standard parts. Viton is the material of choice here. A $25 dial/digital caliper and a visit to McMaster-Carr will get you what you need in 3 days. Stan, the great part about these generators is the ease of removal of the injection pump. Even easier if...

The generator's little issues have all been fixed. The rotted frequency meter was replaced with a new movement, just swapped the dial as the $19 one I found was for a totally different application but had the same electrical-mechanical characteristics. And the low pressure switch was sourced...

I'm certain Cummins has completely divested itself in legacy Onan engines. Ambac has continued to provide parts although the end is near as these engines don't meet emissions requirements. Very low PM but high in NOx.

You have the timing procedure understood perfectly. Just go by the flywheel marks, using a mirror and flashlight to see if the notch in the face gear is aligned. For parts, it would be best to contact a distributor or a local diesel injection service. There may be other items in need or...

If you have tapped on the plunger, it is unlikely that just diesel varnish is the problem. So you need to pull the pump. The plunger turns at half engine speed (1:1 off camshaft) while it strokes to inject fuel. The mechanism which provides for this is probably what has failed...

You should be able to detect the plunger moving while slowly turning the engine over with the delivery valve out. Be sure to lube the pump with clean diesel. The stroke is small, less than 3/16". If the plunger isn't stuck, it will be resting on the camshaft. I cannot imagine deposits would...

:beer:. I don't like the idea of using a punch on the plunger because it only takes a tiny bit of dirt to ruin these parts. Take the delivery valve out and hit it with Berryman B12 Chemtool to dissolve the gunk first. Then if the plunger is still stuck, you can try the plunger tap. I...

Stan, The control lever will not move the piston. The piston is moved by the cam in the engine. This is what pressurizes the fuel. The control collar slides on the piston and controls the volume of the fuel injected by each stroke. It must move freely. The piston also turns to distribute...

Precisely, Peter. I believe the original regulator is a shunt type, single phase linear regulator. The field of this alternator is a permanent magnet type, meaning voltage output is highly dependent on engine speed. Running the engine at lower speed can damage the regulator. Although I'm...

It works like that of a motorcycle's voltage regulator. Current in excess of what is needed to maintain 28.4 volts is "dumped" to a heat sink.

Great news! There is an addictive nature about generators. Something about power:oops:.

Another common cause of no fuel is a stuck IP piston. There is a spring which causes the piston to move towards the cam shaft. If the throttle on the IP is hard to move or stuck, the piston could also be gummed up. See the FAQ on how to resolve this, it is best to use solvent over brute force.

Perfectly. Just let it set up for a few hours before running.
