Both check valves in the transfer pump are leaking. Either replace or rebuild the transfer pump. Parts might be hard to find. The pump can be abandoned in place or removed and blocked off with a plate then use an electric pump. Run it off of the shutdown solenoid circuit. If it is doing this...

You have some good questions. The service manual does not call for any procedure to set the height of the nozzle. The parts manual only shows one spacer being used and available in a single part number. For the shims that are used inside the nozzle to set the opening pressure the parts book...

It most likely needs the air bled out of the injection line, regardless of how good you think it is. The operation you describe is exactly like air in the fuel line. Some of these yanmars are VERY difficult to get a good bleed on. Here is a simple way to do it. Fire it up. When it goes to high...

I just bought an SX460 for under $40 total and it came direct from China in about 10 days with good instructions. I ended up repairing the existing regulator by soldering in 2 new capacitors for about $0.50 each. This was for a 3kw 016B. The regulator in the 3kw 016B is the same as in the 017...

Yes, that is the correct manual section. Perform all adjustments starting with the solenoid #2 procedure on page 7-5 and continue all the way to #12 on page 7-8. Note: The fuel screw is important to get close. You will need a combination of loads or load that equals 3kw. Use the Kill-a-Watt...

Do the full linkage set up in the manual and it will probably fix it.

The oil temp is a great idea. I'll do the same thing. I spent this weekend cutting in a new access door to be able to get to the dipstick easily. I also insulated the exhaust system. another idea is to mount the primary muffler outside the enclosure to further reduce heat.

I'm going to say yes because both a 6 lead and 12 lead machine can be wired for single phase. And being existing 3 phase it is going to be one or the other. However, there needs to be some investigation. Assume the controls will need to be re-worked so the breakers and power meters function...

It's the whole thing. There are four nuts on the outside of the main box holding it on. Mark all the wires carefully. Before you tear into it have you determined that the main A/C regulator is the problem? If the regulator is the problem there are 3 options. 1) Repair it. Possibly a...

Looks good. You are probably going to have to pinch down the flow from the pump to the tank. The gravity return line will only flow so fast. I soldered a plug into a fitting and drilled a 1/16" hole in it. It still folwed a lot so I added a needle valve from the hardware store which gives...

Yes, exactly! I think we all do what we need to to get the result we want. Most of the sets can be made to make power and used. Beyond that, it is the individual's desire of how to restore or how much to invest thus some say they are pretty good buy others say they can be a lot of trouble...

I've dealt with the smaller ones, mostly 3kw and below. All of them need something to be useable, sellable, and to work correctly during test runs. I have found that they have to be run a dozen times or so over a few months time to gain confidence that they will continue working correctly...

I just copied what was already in the enclosure. I will continue to take measurements of temperatures using my infrared gun. However, it is now getting colder so I won't have real results until next summer. What experience do you have that you mention and what are your results? This is my 4th...

It is significantly quieter. I still have a few holes to plug. One of the article I read said that a hole the size of 10% of the area lets out 50% of the sound. I might get one of those sound meters for $75 and take some measurements. It is not as quiet as a Honda 2000 and the sound does...

The 2G40 looks like a current production engine. Some info comes up on searches and there seems to be a few in the marketplace. Did you get the two take outs that went recently at Warner Robins? I saw those. They looked like a decent gamble. The mounting arrangement looks weird and some...

This is what was in the housing before I started. The engine fan sucks cold air through a big hole in the bottom. Mine is sealed around the sides better. The hot air off the engine is essentially forced out through the vents. I have positioned the engine the same and the generator end sticks out...

That explains why those metal tanks are always so spotless! Good 'ol stainless steel. If you cannot make a metal saddle right away why not try the tank bung for the return? It's just hoses and fittings. Easily undone if you change later. If you find the 1-3/4 exhaust tube then just fit a...

2 inches. There is a skin on the outer surface. The rest of it is a single 2 inch layer.

Yes, right now I'm going to monitor temps. So far I've copyed several designs that do not use fans. The MEP-831A with the Yanmar has Two fans but is rated for extreme temps and the fans only come on if the temp gets too high.

Yes, that's what I used on my project.
