Cub Cadet drive hub pulley question

Well-known Member
Ok so a guy brings me a wood splitter to hook up the hyd pump so it spins the right way. Well this engine is a Koler off a Cub Cadet lawn tractor. It still has the drive pulley on the crank shaft end so I need to remove it. It has 3 Allen set screws on it that lock it on. Problem is they are all rounded out and are about a 1/2 inch down onside the hub. Picked up a set of left hand bits and well thy are not worth the $22 they cost since they do not do much more the scratch the Allen set screw. So any idea of how to get this off so I can hook up the pump.
Thanks
 
Originally, there were 2 screws in each hole. One was about 1/2 inch long and the other was used as a double lock. It was about 1/4 inch long. It sounds as if you only have the 1/2 inch set screw.
If you are not going to use the clutch again. I would take a 0.25 inch drill bit and drill the set screws out. After drilling the screws out, take a punch and drive the clutch off the shaft. You will then find a bearing and lock. Take an allen wrench and loosen the locking screw. You will have to unlock the bearing by moving the lock counter-clockwise.
 
Figure what size torx will spin in the set screw. Drive a size or two bigger in the rounded out hole. Have yet to see an allen screw harder than a torx bit. HTH Tom
 
The way it sat I could not get a torx down and in there that I had. I ended up drilling them out and got it off only to find the engine has a bad knock in it
