Lookin GOOD! How does it run?

I viewed your pictures of the Sears M18 in the engine bay with interest because I made the same install in my 782 about a couple of years ago and ran into the same issues. I didn't have a KT17 to swipe the exhaust elbows from, but the replacement KT17 muffler lined up the same way. I used the tractor for a year and I never had a problem with it, even though it was only "slip fit." I also noticed that the CC M18's included an additional heat shield between the muffler and the PTO absent from the Sears M18.

I used the original Sears PTO with an old MTD deck up until last year when I tried to mount a 44C deck and was advised to switch to a Cub Cadet PTO because of the deck's pulley size: The Sears PTO is nominally 6 inches in diameter (and the MTD deck's drive pulley was 5" dia.), whereas the 44C had a 4.5" drive pulley which was matched to the size of the CC PTO pulley. The "opportunity" (read "problem") presented by the fitting a CC PTO to a Sears motor is that the crankshaft on the PTO side of the Sears motor is 1" in diameter; while the CC PTO is designed for a crankshaft diameter of 1.125".

I didn't notice if you told us how you resolved this issue.

I sourced an adapter for the crankshaft from evil pay, but I discovered that the same part is available from McMaster-Carr for about half the price. I've also read (I think on this forum), that a larger pulley is available for the 44C deck that would bring its diameter out to match the Sears PTO, but I haven't been able to verify the truth to the claim, and the pulley for the deck would cost far more than the crankshaft adapter and might possibly require a differently sized belt for the deck.

I have the engine tin from an 1862, but I haven't tried to put it all together yet. It seems to me that the slant at the front of the "Cyclops" tractors is a bit more acute than the 82 series; and I know for certain that the muffler extension is a bit longer.

Like you, I found a socket for the relay, although I scrounged a part from another tractor and fit my own connectors to it. I find there are subtle differences between connectors from different vendors. The different connectors require different sockets to stay in place well, so buying the pre-wired socket as you did is the better way to go; thanks for sharing.

I also didn't realize that I would need to replace the pulley adapter on the drive side of the Sears engine until someone on another forum pointed out its absence in a picture I posted. I'm sure you know all about the importance of getting the drive shafted lined up and vibration-free.

Keep us posted on your progress, I for one will be keeping a watchful eye on it.

Jeremiah, Thanks to Sam I had knew about the mcmaster carr part. I still haven't ordered it yet. I guess in part I don't have a deck for this yet but with all the transtions my fleet is starting to go through I'm going to have to locate one at some point. My plans are to use the KT pto and use the mcmaster carr adapter for lack of better wording.

The wiring connectors were an easy pop out and slide back in. I feel I got a bit lucky in that but I'm happy with how it all turned out.

I took one look at the drive cup and knew I'd have to swap them. Thankfully those can easy be located. Everything lines up just like factory. One of the great things about this swap is using the same bolt holes as the KT 17.

As I figure out the linkages for the choke and throttle I'll post updates when I get those done. Using a #26 prevents me from using the stock linkages, but it shouldn't be much to get those figured out.

Here's the only garage pic you'll be getting and the only one that matters.
