Thanks, The PK block that I have on the outside looks just like the WH block. I was originally going to use the WH, because it also has a 1 1/8" crank for the pto. If I use the JD engine, I will either run a JD ele. clutch or machine a steel bushing to use the Ford clutch. This is a Second Generation LGT145, closed side panels with the rubber iso. motor mounts.


The bolt pattern for mounting pto clutches on 1 1/8 inch shafts is different than the pattern on Kohlers with one inch shaft.... so bushing up a inch shaft to 1 1/8 is not a viable solution.

PK had special order Kohlers made with a ring shaped boss cast into the block to mount the bell housing..... and I am wondering if that interferes with mounting an electric clutch??? On PK the electric clutches were on the flywheel side of the engine.

Thanks, I will look and see if the JD clutch will work on the Ford. If it will, I'll just use it.

Let me clarify.... a clutch made for 1 1/8 shaft can not be used on a a 1 inch shaft bushed up to 1 1/8 because the bolt pattern for mounting the clutch is different !!!!

Brian, older Cub Cadets such as the 107 had the Ford style block. Not sure on the Cub 1650 K341 though as I've never owned or been into one.

Kenny, The info at Tractordatacom says it's a K-341 AQS, and I also thought that the 1650 was a 16hp, 1250 was a 12hp.

Apparently the manual is off. Don't know anything about these. But they do have a cradle the engine sits on, so most likely use the narrow pan.

AQS ..... the "A" is the designation for narrow base. The early JD 200 series had this type engine .... in fact I sold an K321AQS out of a JD 214 to a man who needed an engine for his CC 1450

The QS I think stands for quiet series. They have the irregular shaped air cleaner which receives air blown in from the flywheel

Bring this back up as I am putting together a document with the Kohler build in my 312.  I am trying to spell out the differences in the various Kohler blocks.  Did we establish that there are 3 or 4 versions?

  1. Narrow
  2. Narrow with ears
  3. Wide
  4. Wide with ears???
