Speaking of 12 kW. This is my Onan DJC Just fired up after sitting outside (covered)for four years. 240V, 50A, 1Ø, 1,800 r/m, air cooled. This will power my shop until I get the electrical run.

“but I felt the MF1135 (Masssey Ferguson tractor) was using to
much fuel to produce 4000-6000w I needed.”
Do you know this for a fact? 1 kW of power requires 1.34 HP to produce, 1 HP = 42.44 BTU/min., 1 BTU = 0.0003930148 HP-hr. So what you actually need to determine your anticipated fuel consumption is to know what your engine's BSFC (Brake Specific Fuel Consumption) rate is.
Diesel fuel averages 18,550 BTU/lb. Did you actually run a GPH comparison with a fixed load?
Grumpy:
It sounds like the governor may be “sticking” – Slow on droop response and overrunning. If I understand correctly, your generator handles a 4 kW load @ 240V just fine, but when a starting spike of an additional 7 kW is applied you drop voltage to 234V (acceptable), but then the well pump trips (probably from under voltage protection), but then voltage increases to 245V (also acceptable for a second or two, and the cycles will fluctuate accordingly). Unfortunately, these are not isochronous governors so you are limited to what you can do with them. Do you have any idea what the voltage drop is in your wiring? Wire size? Length of run, etc? What is the HP of your well pump motor?

“Even found I had an old brake riveter, source unknown.”
WOW! That brings back memories. I remember using a brake shoe arcing machine back in the early '60's that would profile the linings after they were riveted to the shoes. It was kinda like a vertical drum sander. Got to inhale all the asbestos dust I that could handle.

You used hose clamps or new ferrules I hope.

There is more to oil than meets the eye. It's always best to make an informed decision when chosing lubricants.
Maybe you've already read this.

“I have ordered 2 brake bands from Circle G. Will post pictures when I get them.”
Two? They will not be segmented, but should be riveted. I think Phillip still has NOS (New Old Stock). Depending on the type of lining used on the NOS bands you may be able to cut the lining in-situ to achieve the new affect.

“Sam reports that the brake drum is only 3/16″ thick so replacing the brake band from the top may help but how many bands before the brake drum will have to be replaced?”
I still find it hard to believe that the drum thickness is only 3/16″ because it is internally splined for the driven discs of the clutch. My experience has been that the drums fail internally from metal-to-metal spline/disc contact and not from brake wear, so I wouldn't worry about that for awhile. Only Yuchai would know the history of the Mean Time Between Failure (MTBF) rate of any of the individual parts and/or assemblies. That's why accurate maintenance records are important.
Predictable failures, what a concept. Been doing it successfully for years (but not with Yuchai dozers).

No crystal ball here. Caterpillar did the same thing many years ago.
It appears that the trailing edge clips are bolted to the band so that they can be removed for snaking around the hub. This is something that will have to be checked on the old bands, and if riveted on both ends may still require final drive dismantling for removal. However, I think the old bands, properly re-lined, can be converted easily for subsequent replacement through the top.

Well, it's probably not “crap” as it meets ( but does not say “exceeds”) API and SAE standards. Their 15w40 oil seems adequate but I wouldn't consider it a top tier product. Doesn't say what base stocks are used, nor any real indication of the quality of additive packages.
Actually, there are a lot of independent refineries that produce motor, hydraulic, and gear oils.

“It may be wishful thinking, but I now want to find out if it is possible to upgrade my dozer to the new brake “system”. At least find out more about it.”
My guess is they used a more flexible brake band and a segmented and riveted lining. Just a guess mind you.
The major thing is that you didn't get stone-walled. I like that. And it also suggests that they are still in production.
