Wet stacking isn't the problem here. That's mostly a generator issue where they run full speed no load. Condensation is the problem. Every pound of diesel burned produces a pound of water. Exhaust has tons of water in it and any blow-by into the crankcase results in condensation. If the oil...

Often, oil and trans coolers spend most of their time working as heaters. The help normalize the oil and trans temps with the engine coolant. Probably best to leave it in contact with the radiator.

Everybody, you do regular oil changes so that your oil never becomes so contaminated that it becomes harmful to your engine. That means that any residual oil left behind during an oil change will not harm your engine. Don't worry about it. As for ATF, your automatic transmission doesn't have...

Automatic Voltage Regulator. It drives the field current on the generator. This is an example of a cheap one. This one will have limited boost for starting big motors. https://www.genpowerusa.com/automatic-voltage-regulators/marathon-se350-voltage-regulator-avr/ Here is an example of a more...

DOL is direct on line. That refers to starting a motor with a magnetic contactor or switch. A 15 horsepower electric motor is going to draw 60 horsepower during a DOL start. The overload duration is short so thermally the generator can handle it. But generator rotating assembly needs to have...

Sizing a generator is fairly straightforward. The nameplate rating needs exceed the sum of all of your loads. AND The nameplate rating must be at least double the largest motor rating for DOL starting. Pick the largest of the two numbers. However, with a VFD the generator nameplate and...

You shouldn't direct on line start a 15 HP motor on a 30kW generator set. The generator won't be able to maintain the pull up voltage on the contactor which will cause it to chatter. This will burn out the contacts within a few starts. Regardless of motor phase you're still going to need a VFD...

15hp 1phase motors are $6000. The same power in 3 phase is $1200. I don't know about wood applications but single phase motors in metal working applications don't produce good surface finish because the shaft speed isn't constant over a revolution.

Oh and mount as much of the controls off of the engine as possible, especially fuses and circuit breakers as they don't tolerate vibration.

Reliable? Keep it simple. I see the military units on here and they're way too complicated. I operate a fleet of 99kW-125kW generator sets. I've got 18 at the moment. I just replaced all of the generator sets as they had up to 35k hours on them. You want a John Deere 4045 engine, Marathon or...

Does it blow bubbles in the coolant when running?

That doesn't look much different than the non-skid deck coating used on ships.

ARP uses a proprietary alloy from Tech Steel called Custom 450 for their stainless fasteners. As supplied by ARP the tensile strength is 170-190ksi. Galling resistance is good. Stress corrosion cracking resistance is good. Toughness is good. Otherwise, you are correct that the typical 304 and...

My suggestion would that unless you see signs of a bearing failure or the pinion nut has backed of is to run it as is. The wear pattern on the gears still looks normal, no?

Recommend by Dana Spicer. This is very important because of you try to set a worn gear sets to new backlash values the tip of the tooth can bottom out in the root of other gear.

Use the rubber piece. Notice the grid pattern on it's surface. That's meant to hold the silicone sealant so it doesn't get squished out.

It is recommended when servicing worn gear sets to measure backlash prior to disassembly and reset to the previous backlash number, not the specified number.

That is 100% a LockNStitch candidate. I would never consider welding that. The big question is, what do you think lead to that crack? The initial condition needs to be addressed prior to repair. I would consider an epoxy repair if it was simply the water jacket but I don't like that it extends...

A voltage sensing relay and some creative settings can get the job done. Mains are almost always 117-120V in my area. Set your gen to run 110-115V and use the voltage difference to trip the relay. You'll need a time delay relay to filter transients.

What exactly do you need repaired? I have a few outside the box recommendations depending on the repair. Also, LockNStitch sells the tools to DIY your own repairs. They aren't terribly expensive, figure $300 to get your foot in the door on tooling plus pins.
