392chryslerhemi Posted June 26, 2014 Posted June 26, 2014 So I have decided that I would like to put a Kohler twin cylinder back into my 7117. . I would prefer a KT17, (Series 1 or 2 ) it doesn't matter. Does anyone have a relatively complete motor they would like to sell, or can someone tell me where I could find one? Thank you. Ryan
Brettw Posted June 26, 2014 Posted June 26, 2014 Ryan, If you are looking for a KT17, look for a series II there is a difference. Not to mention the series II would be a newer, improved engine. Any Magnum 18 or 20 would be the same engine, but a newer version still. All will be hard to find in good working condition, at a reasonable price. If you are looking to rebuild, then perhaps you could find one that, combined with yours, may have the parts needed to make one good engine, however, they are relatively expensive to rebuild. Gasket set and rings 100 bux, connecting rods, same. Other parts to do it properly, machining, etc., and it's not uncommon to spend 600+ on a rebuild. So if you can find a working engine for the 400 dollar range, that isn't a bad deal. But who knows actual condition at that point? Most of them would be 20+ years old, even the Magnums. Good luck on your search, but you might consider other options too, Command, Vanguard, Honda. There are new engine kits for replacement, set up, muffler, misc brackets, drive shaft adapters, etc., but they are in the 2k+ range.
392chryslerhemi Posted June 27, 2014 Author Posted June 27, 2014 Thanks Brett. Would the Command and Vanguard engines be twin cylinder?
Burntime Posted June 27, 2014 Posted June 27, 2014 A Kohler Command 18 plus is a dynamite alternative. Hondas although not factory are awesome too.
maxtorman1234 Posted June 28, 2014 Posted June 28, 2014 There are articles on here about converting a vertical shaft magnum to horizontal shaft. If you still have the engine that was originally in the tractor you will have all the parts you need for the conversion. The vertical engines are usually in VERY good shape, close to new as the machines usually fell apart after a couple hundred hours. The commands are great but aren't a direct bolt in, same as vanguards. I have owned all of the engines mentioned and would never consider a vanguard. Just my opinion though.
392chryslerhemi Posted June 29, 2014 Author Posted June 29, 2014 Thanks for the info. What kind of modifications would need to be done to the tractor for the Commando motor?
maxtorman1234 Posted June 30, 2014 Posted June 30, 2014 The Command engine will require a different length drive shaft(this topic has been discussed a fair bit on here and I think there are several posts on here detailing what you will need) I just used a 300/400 series shaft with the flex plate instead of the rubber coupler, even though I have 4 or 5 spare, it was easier. Also for mowing most people recommend the chopper screen and blower housing, which is expensive from Kohler. Even though I have a spare, my this is my last Allis machine and will never see a mower deck again so I just went with the standard screen, and also the 2 rear bolt holes will need some kind of spacer made up as they line up with a stamped out section in the frame. I also drilled a new hole for the oil drain. Nothing too extreme, and of course a muffler that fits right. I think that is all I needed when I did my CH25 into 917.
RayS Posted June 30, 2014 Posted June 30, 2014 25hp, now that would be sweet. Burntime would be proud:D.
392chryslerhemi Posted June 30, 2014 Author Posted June 30, 2014 Where are the exhaust outlets on the Command motor? Would I be able to use the muffler from a KT17?
PhanDad Posted June 30, 2014 Posted June 30, 2014 The exhaust outlets come out the front: I doubt the KT17 muffler will fit; I would think the exhaust ports are farther apart on the horizontally opposed cylinder layout and the bolting layout is probably different as well. It might be modified to fit.

It looks like what is on my Sovereign 18 and Bill`s post in show and tell. It is $122 at jacks. I do have a Triad wiring harness, engine coupler and driveshaft if you need them. You would have to do Bill`s modifications to the wiring harness.
