Is it a spark-ignition or compression-ignition engine?

I've seen these units. How do they run on diesel? Are they like old muti-fuel tractors that preheat the heavier fuels to make them burn?

That should be a standard SAE 5-bolt fuel sender gasket.

I've replaced that bearing before. Here is a two-pack of Timken bearings on Amazon: https://www.amazon.com/dp/B08DCFQXTB?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_5

I finally broke down and bought a used pallet stacker to help get the generators off the ground.

That would be very cool to have if the price was right. The neighbors will love you!

The 803a units are a real gem. Powerful, reliable, simple, efficient, quiet.

You stated anything above 2000 watts causes surging. Surging usually implies the engine RPM (and gen freq) are hunting up and down, and unstable. You also mention the overload light comes on. These are separate issues the way it's described. Surging is usually a droop adjust or sticky...

That would be great information to have. I did some napkin math and believe the isolators should be softer to reduce transmission of vibration to the skid, but that would likely come with increased vertical motion of the engine, impacting wires and hoses.

It seems like a flaw in the design to mount the engine/generator assembly on 4 points. Most automotive applications mount on three points to avoid torquing the drivetrain. Generators get away with 4 because the isolators are typically soft enough that small differences in height do not have a...

VIBRATION PROBLEM SOLVED! I had made myself a list of things to try from pop-testing the injectors, to swapping the isolators, to changing the engine out with a spare. While pulling the engine isolators, I noticed it was harder to lift the left side of the engine enough to free the isolator...

Reviving this thread: I pulled this thing apart last year and measured considerable runout at the end of the rotor shaft. Some was flexing of the [35] plate, but I fully disassembled the whole rotor, adapter plate and flywheel, measuring excessive runout on each interface. I've designed and...

There is a plug you remove on the front of the engine and an adjuster underneath. Page 4-16 and 4-17, droop adjustment. Increasing the droop will make the generator more stable. https://www.steelsoldiers.com/attachments/tm-9-6115-641-24-old-pdf.888627/

I made a couple of holddowns out of some 1-inch 6061-T6 aluminum angle. I heated the ends with a torch to soften the temper and then flattened it with a hammer. The J-hooks came from Walmart and fit perfect.

Read the other post, but the overload light can likely be solved with Deoxit. ( I just did this today and my 802a pulls 5000 watts without issue) The surging may be a result of an over aggressively tuned droop control. This is pretty easy to adjust.
