Is this K90 a gear reduction on a 53 generator?

[stevebo-(Moderator) 8,059]

Guys,

I just bought this 1953 generator with a K90 with Schnakee recoil. Anyone know if this is a gear reduction?

Steve

If it's a gear reduction unit you should see a cast add on gear box piece on the crankshaft end of the motor about 2 inches thick as it's external not internal

from the pic's it looks direct drive to me

Steve being a generator I'd think they would want to spin the armature as fast as the motor would run and not be reduced in speed. Just a thought... :banghead:

Most likely not a grear reduction but I believe it will have a special PTO crank shaft. It might not be 3/4 keyed :banghead:

Lots of generator applications use a tapered PTO shaft, but finding a crank to swap shouldn't be real hard, that recoil was a nice find.

There it is........ tapered! My mind totally went blank there for a few.

Finding a good 3/4" keyed crank may take a little work though. I know MikesRJ looked for a while for his. Unless money is no object :banghead:

This unit is super clean !! Runs perfect !! This is an actual kohler generator. It fired right up and I am real happy with it. This motor has a larger oil pan that is different from most. If I put it on one of my RJs then I guess I have some work to do. Based on how it runs it will be worth the effort. Check out the video of it running.

That is AWESOME!

It would be a shame to take it apart... A true piece of history! It would look great as a display at the shows.... Or, make a hitch mount and put it on the back of a RJ... :banghead:

[stevebo-(Moderator) 8,059]

Jon,

I agree !! As much as I would love to see this motor mounted on one of my RJs or 400 I do not think I have the heart to do it !! It is very heavy so mounting it may be an issue.. Maybe I can make a small cart to pull it around :banghead:

How about a miniature version of the 4-wheel wagon.... with the generator mounted inside?

Or, a front mount on a Suburban or other round hood would be AWESOME! :banghead:

Jon,

You suck ! Now you have me thinking and I need to do that for the show !!!

[Kelly 1,028]

I agree that is just to cool to tear apart, I'm sure not many that nice left.

That is sweeeet! Nice score Steve and can't wait to see it in person.

[Docwheelhorse 2,561]

Sounds real nice.... but is it screaming???? the R's sound high to me---unless they turn these K90's to 4000????

That is just too cool Steve! :thumbs:

[stevebo-(Moderator) 8,059]

Tony,

The gen plate says 3600rpm and I agree that seems hiher than 3600. I will have to have my buddy Ken B check it with his digital rpm gauge before running it again... :banghead:

You could also check the AC voltage output at the generator, Steve.

If it's over 120 - 125 VAC, you could slow the engine down some.

Nice unit, I bought one the past summer for the k-90 engine, the oil pan is wide as the genarator base is part of it, it runs great and genarates power, I need to weld the base it is cracked, no big deal. mike

according to my kohler manual, these are governed at 4,000 insted of 3,600 rpm.

A K90 is 3600 rpm (3.6hp) & a K91 is 4000 rpm (4.0hp)

Steve: is THIS the same generator? :banghead:

[stevebo-(Moderator) 8,059]

Looks exactly the same. I will go check the Kohler model number.

[stevebo-(Moderator) 8,059]

Here is the info on the Kohler Tag on the actual generator (not the motor)

Model 1.5M 25

Serial 198 787

Watts 1500

Volts 115AC

RPM 3600

I would assume that is decent output. My Honda puts out 2000...

[wheelhorse656 20]

nice piece of history. i agree with the others dont tear it appart! :banghead:
