I'm glad you got the right result, even though it took another engine. The troubleshooter in me would tear down both engines, and compare what's going on side-by-side. I just want to KNOW, especially on something so weird like this-- add it to my encyclopedia of stuff. I'm seriously thinking...

Get a dry, clean, empty milk gallon jug. Pull the supply line off the injector feed side of the filter. Attach a tube long enough to get into your jug. Flip the switch to prime, and that jug should be pretty close to half-full within 60 seconds and have a decent spray with each pump stroke. If...

Did you try feeding a little compressed air into the intake while running to see if it smooths out at load? You fixed the compression issue, so you're down to either fuel or air. The only other thing I can think to try here is pull the injector, the hard line, and soft return. Turn the hard...

A lot of diesel farm equipment I deal with gets purged with straight ATF for long sits. Always a good dose in the cylinders as well. It will burn just as well as diesel. If you really want to go nuts, you can purge the entire crankcase, intake, and exhaust with dry nitrogen and seal it off...

Can confirm that reasonably filtered WMO will *probably* foul up your already fouled injectors and reduce available power leading to disappointment and or depression. Could have been a coincidence too, because the tank was loaded with gunk on arrival (removed and cleaned before placing into...

Really nice job. I can't believe how much love you put into an 831. Give everything else a good double-check before you're done, especially the cooling fans. The inverter cooling fan should turn on with the switch in the run position without engine running-- you should hear it. The other two...

I'm a mechanical contractor specializing in refrigeration. Burning refrigerant, even at relatively low concentrations results in the creation of phosgene gas. It's mostly applicable to older chlorofluorocarbon and hydrochlorofluorocarbon (CFC / HCFC) refrigerants, like R11, R12, and R22...

Thank you for that study!

Hey, Does anyone here have experience burning waste oil in 802/3s? I'm looking to make about 150 gallons disappear, and just wondering if anyone had a negative outcome? I'm mostly worried about clogging the injector nozzles. I'm aware that burning waste oil isn't exactly ideal, but older...

Yes, red arrow is the sender unit. MT5 is the sender, and M5 is the gauge. Full tank should read 29.7 to 36.3 ohms, and empty tank should read 216 to 264 ohms. Your 50something ohms *should* be reading a basically full tank. Here's the test procedure for the fuel gauge. You use the voltage...

I've been swapping out relays for cheapo Chinese ones from Amazon. They seem to work just fine and are an exact match for the plug. Just make sure that you order the proper coil voltage, and that the blade configuration is correct for the plug. Also verify orientation of NC / C / NO contacts...

Thanks Ross! There's so many people here generous with their time and knowledge-- I'm always willing to pay it forward. For the record, I'm ashamed of my generation.

Ross brought the generator over my house today, and we managed to get it running just fine! Injector pump rail was jammed, and one or more injectors weren't lined up. Took a lot of patience. The second after we called it for the night and he drove away, I finished bleeding for the 4th time and...

You only need to remove the rear lower back panel going around the fuel filler / aux fuel connection nook. All of the 5/16" machine screws around the left, top, and right and filler have captured nuts-- nothing should spin. The bottom fasteners are 3/8" with nuts, lock rings, and washers. Those...

On your fuel gauge problem, you'll want to take the rear lower panel off and just take that float / sender module right out. From there, theres just a resistor strip and two contacts. The entire module comes apart, just clean it up nice and good, and it should work just fine again. You'll also...
