Wow, I had to look up that model. Not to be the party pooper, but 100 kW is a lot of generator to keep loaded to avoid wet stacking.

Fuels lines are notorious. Funny, my oldest 1994 unit had the least issues with lines, the newest 2011 had the worst line cracking. The governor and fuel rack linkage are a little complicated, but not terrible. I would review the TMs, pull the front cover and exercise the linkages. You may...

After watching your video, I suspect something in the fuel rack, governor flyweight assembly, or injection pump(s) sticking or catching. It's acting like the engine is getting slightly too much fuel, slowly increasing in rpm until there is sufficient force to "pop" the rack loose. Then it...

Two thoughts: 1) If your control cable is broken, maybe the input to the governor control is moving around on its own, causing your fluctuating frequency. 2) There is a speed droop setting on the governor that makes it more or less aggressive to changes in rpm. If it's set too aggressive, it...

That's just sad, but I've seen evidence of downturn for a long time now. I had an 802a on Marketplace for weeks at half the price of other units and only got two scammers. Ended up selling it to an acquaintance for his off-grid cabin.

I have refurbished 6 of these units and power washed each one inside and out. I avoid directly hitting anything sensitive like the starter/alternator, electrical box, sealed bearings, etc. Use a degreaser/cleaner, like Simple Green. Oh and disconnect power first.

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.
