MEP018A 10 kw genset questions

This is 1968 gas Hercules powered . Plate says overhauled by TEAD, mfg of generator says(unknown). I just got this unit from a GSA auction. Looking for basic info and TMs. Looked on this site for a while. I realize this info is in front of my nose, but I haven't found it. Besides TMs, want to know if anyone ever converted this to propane. Thanks.

The TMs for the genset may be in the resources section, but probably not the one for the engine itself. TM 5-6115-275-12 and -35 don't cover the engine, but should be in the TM5-2805-204-14.
There are generic kits for converting to propane.

Both TMs should be in the resource section

If the engine TM is there, please point (TM5-2805-204-14?), thanks.

I found it in there but it is filed as TM9-2805-259-14, which apparently supperceded the TM5.

Thanks, guess it helps to know what to look for.

Propane carbs are available. I can't for the life of me remember where from though. It's been years since I had mine. Maybe a Google search? (Saturn Surplus, maybe??)

If running on propane, expect to de-rate the output by 10-15% due to the lower BTU value of propane.

ever find a propane conversion for the 4a084 engine?

Piece of cake!

Military Surplus Propane Natural Gas Generators

Thankyou for the link, but I'm still not so sure about this "kit". From what I can see, they are simply pumping propane into an opening in the carb. This is fine and agree it will make the engine run, but what if I want to change speed or for the case of the Gen-set change the load? I do not see how this kit regulates the amount of propane being pumped into the system... Ditto for when the engine isn't running- no "shutoff" aka if I shut down the engine, how does this new system stop delivering propane to the carb since there is no "float" like the gasoline version.

Propane conversion- how it works

Ok found more info... they use a vacuum cutoff to safely shut off the flow of propane when the engine is not running. The venturi effect is what actually pulling the propane into the system... opening the butterfly valve via the govenor causes more suction on the new propane jet causes the diaphram to open more, thus giving more propane to the engine... The propane jet doesn't seem that complicated, pressure regulators cost around $50, so why such a high price tag? The other concern is that the 4A084 engines do not have much clearance below the carb bowl for their adapter hose.
