Hi all, I'm in need of the stub shaft that bolts to the Kohler flywheel for the Warner electric PTO for the project tractor, will a stub shaft from a Case 444 work?

PK used 1" and 1 1/8 shafts and the earlier flywheels used 5/16 bolts with a little smaller pattern than the later ones with 3/8 bolts.

Thanks username, if I got this right the shaft dia= 1" and the length is 1 1/8", and I got to also check if the flywheel threads are 1/5ths or 3/8".

Yesterday I bought 3 Kohler K321's 2 pretty complete and one about 75%, thats the good the not so good is they ha short crankshafts (they had hyd pumps attached) but I have a crank that can be ground to use. and they have the short oil pans.

No,PK used a 1" shaft and they also used an 1 1/8" shaft depending on the hole size for the clutch.Most of them are 1 1/8..Far as I know the engines prior to 1974 with a belt pulley used 5/16 bolts and the electric pto models used the 3/8 bolts.

Hi username, ok now its making more sense, I went into the shop and measured the clutch bore its 1.125" and my flywheel bolt holes are 3/8" with approx a 2 7/8" spacing for the mount legs, are they all machined on the flange end for the flywheel nut? I came up with 1 3/8" dia and 1 1/8" deep.
