Hey guys, I'm having difficulty trying to get a comet duster off of my Kohler k-340 2as. I made the puller myself to specs for the duster. It seems to be working fine, I've used heat, and grease and still can't get it to budge, are there any other tips I might not know about. Never had a clutch be this hard to get off.

I've heard of the water method but its only 37 here in MA so unless I want to wait a week or so until its "supposed" to get colder I'm SOL on that.

The Cat hex clutch puller will work also on a duster. It works on the Rupp clutches also. Make sure you have a plug stop in the cylinder and your stud you put in the clutch to run the bolt agaist is the right length. Tighten bolt agaist stud good and tight get a 1 inch aluminum shaft and rap on the head of the bolt. If you want heat the shaft on the clutch than rap on it. Than tighten the bolt some more it will pop off. Make sure that you put the pulling bolt in the clutch at least a 1/2 inch.

The water method is: remove the clutch bolt, tip the sled so clutch is pointing up, fill the bolt hole with water, teflon tape a bolt and screw into the clutch which uses hydrolic pressure to pop off the clutch, you can allow it to freeze if it is a stubborn one, I never tried it but apparently works!

Hmm, I thought you had to let it freeze, I'll have to try it tomorrow. Thanks!

They say to use the bolt that holds the clutch on but does not make sense to me - I would use a bolt the same size as the puller or use the puller. Google it and there are many videos doing it on youtube

Leave your belt on the primary and secondary clutches so when the primary clutch pops off it doesn't fly out and cause damage

I would still put a belt around it and attach to something, on the floor on a big rubber mat would be safer, cat clutches are capable to accept a 2' crescent wrench to hold it against the floor and use a breaker arm on the bolt- step on the breaker arm while holding on to something so you don't fall down, newer clutches accept a holding wrench around the outside, large strap wrench may work on a comet, if it's junk put a pipe wrench down on the center shaft to hold it

Still having issues trying to get this damn clutch off, I tried the water method with the puller, that didn't work. I tried heat, and I tried grease. I brought the motor in the house to my basement workshop to let it heat up a bit and strap the block to one of my I-beams and really wrench on it. I'll recuit some muscle as flab can only provide so much force.

Water tricks is awesome and been using it all the time, I use antifreeze for prevent to freeze up or oil, (oil is messy to clean up) okay get a bunches metric bolts from hard ware store that's fit in clutch ur use ur clutch puller. (U don't want to use the bolts that screws in the crank, u want the bolts screw into the clutch) ull see the thread inside the clutch housing, put the tape on the bolts thread, make sure u put a plumbing tape in right way otherwise if u put the tape backward will unwrap while screwing in. U have to put enough tapes like a lot and will screw in hard and u want that to help to seal to build pressure, put something in flywheel starter wheel to hold the crank for you without turning while u tightening bolt on the clutch, tilt ur sled sideway and want the clutch facing up and fill with water to full no air pocket then put ur bolts in and start screwing in make sure it doesn't leak any water thru it if see little water like tiny bit is ok, after u screw in til it gets hard, u can put ur sled down and quickly start tighten the bolt fast it will get very hard, just keep turning, then I grab my hammer to tap on bolts hard should pop out, if not then keep tighten some more, it can pop out while tighten so watch out it will scare you boom. I can post a video how to and I have few sleds that I need to get the clutch off so let me know

Thanks for the instructions. I think I can get it done the way I have it strapped a support beam in my basement workshop. I'll let you know how it goes. I'm sure a few people would like to see a video of that. I know I would. Again thanks for the help!

They can cause some physical damage if it hits you!
