It was a VW clutch and pressure plate as far as what style I could not say, a steel flywheel is made that will work on a Kohler crank and is made to accept the VW clutch and pressure plate. Chuck Vogel use to make them and all the parts associated with them. Years ago before we had good clutches a lot of pullers used them, I have a feeling we may be going back to them in the next few years. Some new stuff has come out that bumped the numbers some more, I should say some new stuff to go with stuff that has been around for decades, anyway the clutches we have now are starting to falter again. Some of the pullers I talked to say they loved the VW clutch because it did not slip once engaged and some I talked to said they had trouble slipping it off of the line. But I seen a few of them abuse them off the line and done really well. I know Chuck Vogel had one in his blown tractor and had good luck with it. I may go to one in the next few years, depends on how things turn out this winter.
