Well, my K341S blew a hole in the block and getting another one around here is like finding chicken teeth :wallbanging:

 

So, I have scrapped my pennies together and picked up a Kohler CH20 OHV motor to try and power this thing.

 

Has anyone here done this before?? If so, any helpful hints?

I have not done any engine repowering yet, so I am interested also, as I am having K321 engine troubles.  Noel

One issue is always crank height. If you have a u jointed drive shaft it isn't as much of an issue. Could you take some pictures and post some info about the re power? It's becoming more common to re power the older GTs as the engines are wearing out after 30+ years of use.

We took out a Kohler k 241 10hp and easily replaced it with a CH 18 vtwin (same size as a 20) and only had to re- wire the ignition to shut it off and drill 2 new motor mount holes !! It was retardedly easy and the V twin is super smooth and crazy powerful!!! And all this under the bonnet of a Ford LGT 100 .

The Command is a popular repower for 900/7100 series tractors. The CH18 became standard power for many late model Sovereigns. If you do a search on it over at simpletractors you find find several tutorials.

Closed sided machine , Tom. And I'msure it could be done to the open sided units with bolted in engines (late model open-sided units)and a fuel tank relocation.

Did you do this on a 916??

On mine the crank looks to be maybe a half inch lower than the drive shaft and the holes where the motor mount bolts go thru are much larger than the one for the K341 that came out.

What did you do to attach the crank to the drive shaft??

As for the rewire, what did you have to do with that part?? I really don't want to fry any of the electrical stuff.

 for the driveshaft I used the same adapter that was on the K series , bolted right on . As for the motor mounts, they are different on the Fords. They are 2 separate plates mounted on rubber. For your app. I would get the engine lined up by shimming it and re drill the 4 holes. Then for ignition I used a relay. wired so the ignition power opened the contacts that would ground the ignition cut off wire to ground to shut off the ignition. Worked perfectly.

skyryder2, when I get to the rewire part of this I will be picking your brain, wiring and me don't seem to follow each other very well :D
