782 Engine

[CoRd59]

I picked up a 782 a few months ago, it has a red M18 in it.

I did a bit of searching with the spec number, only info I found was, Made for Grainger.

I'm wondering what this engine would have been used in, or used for originally?

[Billy-O]

Perhaps the motor was a new replacement motor that a PO purchased from W. W. Grainger, which is a big (and pricey) industrial supply company?

I agree with Billy O
Those M-18's were very popular, being used in skid steers, mowers,ariel lifts,irragation pumps, electrical generators, and just about anything that needed reliable power at a fair price.
Had it not been for emission requirements, they prolly would still be producing them.

FWIW, I asked Copilot "What application was a Kohler engine, spec 24543 used in?"
The answer.....

Thanks for the insight on the M18. It's my first kohler cub, my other 3 cubs all have kubotas in them.

I don't know any history on this 782, since the PO had passed away, and the only thing the person selling his estate knew about it, was he had sunk more time & money into it than it was probably worth.

Another question I have about the engine. Is there any hopes of putting a PTO on this engine? The PTO shaft is broken.

Maybe, the cub spec engines are pretty short. I think they are 2 and 5/8 inches. How long is this one at the shortest point?

[CoRd59]

It's approximately 1-7/8" at the shortest part.

Ya its a little short by about an inch.
You could get a good crank on Epay and have it assembled in 1/2 a day if the engine is in good shape otherwise,

Nice front hydraulics

Is it broken or did the PO cut it off really poorly?

It seems to run well. It does not smoke at all. Or make any strange noises. I have not really used the 782 for much in the few months I've owned it, other than moving my log splitter a few times, and pulling my firewood trailer around my property once a week. That's about all I have done with it. I went outside to use it the other day to move some firewood up to my house, it had been sitting for over a week in a unheated shop, single digit temps at night, it started fine, 1/2 choke, about 1/3 throttle, it came to life. It seems healthy to me.

I'm going to try and find a crankshaft local to me, before I go the eBay or online route.

I've been reading over the the M18 engine parts list, comparing part numbers, M18 made for Grainger, and M18 made for Cub Cadet specs.

The crankshafts and closure plate, have different part numbers, all other part numbers, bearings, heads, block, cylinders, flywheels, etc, seem to be the same, on the two engines. I assume the closure plate has a different bolt pattern for the PTO? And the crankshaft in the Grainger M18 are a different spec as well?

I'm tempted to hunt down a M18 Cub Cadet crankshaft, and closer plate, because I think they will be easier to find. Unless you can direct me otherwise? I think a Cub Cadet M18 crankshaft and closer plate should plug and play with the Grainger M18?
