Would anyone know what size the output shaft on a K181 out of a Wheel Horse would be?

Thanks,
Mark

That sounds right to me. I believe that most of the Kohlers (and Tecumsehs' for that matter) on the Wheel Horses had the 1" output shaft.

Had to check cause you got me to wondering.
The horizontal Kohlers, Onans and Tecumsehs 10hp and up are all 1-1/8" shaft. The Charger 9 is also.
The Briggs and Strattons used in the WorkHorse models are all 1".

The first manual pto clutches were different. In the end the horizontal pto clutches are all the same. The difference is the diameter of the hardened sleeve the needle bearing runs on. Comes in handy if you are replacing an 1-1/8" shaft with a 1" - just get the sleeve for the 8hp models or a B&S engine.

The B&S engines will not take the end pressure exerted by the manual pto clutch. They added a thrust bearing behind the drive pulley to make them work. On assembly you leave the drive pulley set screw loose and install the clutch. Then you apply the clutch to preload the bearing and then tighten the set screw.
