Default Kohler rotor is toast

The rotor on my Kohler generator is toast. The local authorized dealer estimates a replacement rotor and regulator at $4200 and the total repair cost of $6000. Clearly time for a replacement head.


Looks like a 164D from Central Georgia Generator will be the most economical choice. Can anyone give the bell housing and Drive Plate SAE sizes for the setup with the Yanmar engine in the 1987 PTs?


Thanks--

I have a Kohler rotor and the price is right!
You pay the shipping and it's your's.
I'll throw in the regulator too. (it reads just a little high)

Thanks for the offer, but since the labor cost is the same I think I prefer to go with a whole new head rather than repairing the old one.

Hmm
Is your stator still good?
I might be able to use it.

Troubleshooting was performed with the generator still mounted in the slide. The stator was reported as good. I'd be happy to gift the Kohler.



I don't have a home base to store the unit after removal. Current schedule is for the r/r on Aug 16-17: Will you be in the DFW area then to pick it up? Or it could probably be shipped on the pallet from the new head.



Contact me if interested.

I used the 164C 13.5 KW from CCG. When I mentioned the 164D, the owner advised me that the Yanmar didn't have enough horsepower for a 16 KW, at least not enough to get the full 16 KW out of it. It's also heavier, and since the generator head on a Yanmar hangs unsupported off of the engine, I opted for the 13.5 KW. JMHO

John:


You remember which bell housing and drive plate sizes the Yanmar uses?

I'm sorry, but I don't remember for sure. One was 7.5, I think that was the drive plate. I've seen the numbers here on the forum somewhere. I probably posted them at the time. I'll look.

OK, it was 4/7.5 The 4 is the SAE engine bolt pattern and the 7.5 is the drive plate.

Ordered a 164C From Central Georgia Gen, which arrived in a few business days. Bell housing and adapter plate ordered in size SAE 4/7.5. First step took 4 hours:





Bell housing and adapter size verified correct.


Drove coach back to campground, now waiting for rear main seal parts.
