4g64 engines in generac generators

[Guy Farting]

So this was new to me. I was at work out in the field and I Service and repair generators of all sizes. Everything from personal 5kw Hondas to quad supercharged and quad turbo 16 cylinders.

Then I'm at one and I realized the model number on the block. I was like wth? Then I looked at the valve cover. Sure enough it's a 4g64. Could I use a crank from this unit in my 4g63?

Looks exactly like 4g64’s that came in 2g spyders.

That's crazy! Are they wide blocks or narrow block 4g64? I would assume the crank would work. Can you find any service documentation or anything?

Those would likely be 7 bolt motors.

I wonder if they have the same internals. They're probably not meant to be revved out to 6500 rpm. I wouldn't think so anyway? Although it would be easier at a production plant to assemble all the engines the same way.

Mitsubishi motors was still manufacturing many 4g63/64 in China for Chinese market at least till a few years back (maybe still is) with Chinese/south asian companies. This one is one of those.

so the funny thing is I have a full Service Manuel on it and this one was produced in 2015. I'm going to dig up as much info as possible. Maybe even post some schematics and diagrams that would help anyone out.

Double post sorry. This one is hilarious when it starts up. It has a coolant heater on it that keeps it at 170 degrees 24/7 and when it starts up it goes straight to 3600 rpms in 1 second. Since it's a 2 pole Gen set it does twice the normal 1800 with a 4 pole end.

Funny enough the Manuel notes there's a 2.351cc engine(the 2.4) and a 2.349cc(2.3)

Found some basic wiring diagrams however these run off of lp gas and the controller is proprietary so I'm not sure if the pin out means anything but still kinda cool. I will be looking for the engine manual. Maybe I can get the shop to order it

About what RPM do they run that generator at?

This one runs at 3600 rpm at all times
