With the virus going around, I am finding plenty of time to work in my shop, and ran across this test I started on 18 March 2018. This is a final update of my Fernco diesel soak test. These parts have been submerged in diesel for almost 25 month. The final results are the same as in my last...

Are you referring to the drain bushing on the tank? My fuel shutoff is on the fuel filter. The drain bushing is a "well nut" type bushing. I replaced those with a brass bulkhead fitting with a viton "O" ring and pipe plug. (Same size as used on my Mep-802A -...

Search on Amazon for "Electriduct Rubber Grommet Seal Gasket O-Ring Bushing - 3/8" x 1/8" x 1/2" x 5/8" x 13/32" - Pack of 50 Grommets" I copied that description from the site.

I have been using these generic bushings on my 531 and 016D's with good success. They are made by Electriduct, from SBR rubber, and are available on Jeff's big "A" site for about U$D 16. The only difference is that the Yanmar has a slightly larger flange on one side, which does not appear to...

I recently had a leak on my truck engine. Ordered some Tracerline UV dye for oil (they make one for oil and one for coolant), and a cheap UV flashlight off the big "A" site. Amazing how easy it was to find the leak in the dark. Any seepage with the dye will glow brightly. (And so will your...

Guy, I have the cover off my 802A, and my A9 module wires have numbers on them (magnifying glass size). The tie wrap on the generator side is labeled with the plug number P-15, the float side tie wrap J-12. The wires on the float side, going to the J-12 plug are numbered 1F, 2F, 3F, 4F. The...

If you disconnect all the wires going to the exciter and voltage regulator (tape them off individually) you wont damage the generator. The generator will not produce any power without excitation.

Here is an update on my Fernco diesel soak test. I placed the remnants of my Fernco coupling trimming in a jar of diesel on 18 March 2018. I just found the jar, while looking for some other items in my shop. These parts have been submerged in diesel for almost 6 month. The plastic has hardened...

The motor shops dip the windings into a polyester resin, then bake the winding to cure the resin. For severe service the winding is soaked in the resin under a vacuum, then under pressure, called VPI - vacuum pressure impregnation. That is what I would spec for your windings. There are also...

I am back in town, and plan to get the set up and running in the next two weeks. I tested all the electric components with a 24v power supply, and all relays, lights, fuel pumps etc. work as they should. Now need to get batteries, fill the oil, and then start flushing the cooling system. I found...

I get all my stainless fasteners from this place https://www.albanycountyfasteners.com . They have just about anything you need in stainless. Oops, posted in the wrong thread.

I just ordered three sets from Rock Auto. $5.34 for all three, but $8.95 for shipping. Grrrr.

Depending on the type of charger you have, the inrush current of your battery charger could be too high (sort of like starting a large motor). What is the current draw of the charger, and does it also show the inrush current? Are your 40 amps at the 110 volt setting?

I suspect the crud was silicates. I could squish it, and it dissolved in boiling water. I connected the cooling system to my washing machine hot water faucet, and ran lots of hot water to flush out most of the crud. I will flush the system several more times before filling it with antifreeze...

Had some more time to work on the set again. Cleaned up the fuel tank, replaced all fuel lines, installed a new "FERNCO" coupling and took "Light in the Dark's" advice and replaced the thermostat. Glad I did. The picture of the thermostat and housing are self explanatory. Amazing what shows up...

I decided to pull off the radiator hoses today, since I heard and felt a significant "crunch" when I squeezed the hoses. Turned out the springs inside the hoses were rotted away. Lucky I caught that, before circulating spring particles through the cooling system. (The cooling system was drained...

According to the FERNCO website, the fittings are made from PVC. Their chemical resistance chart does not include Diesel, but they marked Kerosene as "not recommended". Since this coupling does not hold any pressure, I don't think it will be an issue. I cut up the leftover piece I had from my...

Had some more time to work on the set today. Replaced the upper well nut, and replaced the fuel return hose. I had to fish the fitting in with a wire. My arm made it into the tank, but could not get to the fitting. Those brass & O-ring fittings should last for the life of the set. I used some...
