Question Kohler 4.5cm21 generator help needed

I just got a Kohler generator model 4.5cm21 with a k341ep engine. I was able to go to the Kohler web site and get the manuals for the engine. Does anyone have schematics for the generator part of the unit? This unit was in an old RV. I’m trying to make it work for emergency duty.

I will try to post a picture later today.

Any help will be appreciated. Thanks

Default Re: kohler 4.5cm21 generator help needed

I searched the Kohler web site and was unable to locate a manual for mine. Is yours in a PDF format?

Did you ever get a schematic? If so I think I need the same. However, my model # is:

Model #: 4.50M21-RV
Serial #: 042471
Spec #: 13912A

Watts: 4500
Hertz: 60
RPM: 1800
KVA: 4.5
Amps per Terminal: 37.7

Class: F
AMB: 40 centigrade

Battery Charge 12 Volt, DC 7 Amp

Is this the same as yours?

Thanks

Talking Re: kohler 4.5cm21 generator help needed

I have a .PDF file for a 4.5CKM21-RV I am wondering what the difference
between that, and the 4.5CM21-RV, which my neighbor has, would be?
If one of the Kohler Gods could tell us, I for one, would greatly apperciate,
and bow down to the east, multiple times.......

According to the compilation of info that we put together, the K stands for a Kohler engine, B for Briggs & Stratton.

http://www.oldengine.org/members/die...KohlerCode.htm

If there is neither letter, I haven't a clue! :-))

Possibly it was left out if the engine was only available as a Kohler.

If you look under the "COntroller Box", it may be taped to glued to the underside. If not, let me know and I can try to copy it and fax to you

The 4.5ckm21-rv 1s a two cylinder horizontal opposed engine. The 4.5cm21-rv is a single cylinder vertical engine.

Randy, that's exactly the schematic I need !

But I can't quite read the little numbers and such.

My software says it's only 200dpi.....any chance you could rescan it at 300dpi or 400dpi, and post again?

That'd be great!

thanks very much,

Richard

Talking Re: Kohler 4.5cm21 generator help needed

These units have an "Idle Down" mode, where the engine goes from
Generating Rpm to Idle, when there is No Load present. If you connect
a load, (Light Bulb), the unit will sense it and stay at Generating Rpm.
It is considered a "Feature", not a malfunction. It is designed to save
fuel, when not loaded.
