Great video. I'm having alot of difficulty removing the set screws. I soaked them in Kroil for several days but they still will not buldge and i'm affraid I will srtip them if I apply more pressure. Can I put heat (oxy/acetylene) on the groove of the pully/PTO to remove them? It's my last resort but i'm worried I may mess up the metallurgy on a high RPM part or am I thinking about it too much? First post here guys, I have a 129 i'm thinking about restoring and this motor has been apart for years... Joe

I know mine were not going to come out untill I took a .30cal. bore brush using a drillmotor and swab'out the hole, blow out hole to clean. Then maybe the screws will work their way out, depending what screws your on.

Thanks for sharing this video. I have a 104 that I have to remove the clutch and keep putting off and now it doesn't look so difficult.

I had to drill and re-tap one of mine, and another one had already been bored out by one of the PO's.. who knows in 40 years which one performed that service? At any rate.. used a helicoil kit in the bored out hole... my biggest complaint about the PTO are the "locking" nuts that attach to the pressure plate screws.. mine ALWAYS work themselves loose.. I'm thinking nylocks next time.. it's sort of a pain to pull the whole assembly just to reattach those silly nuts... and yes.. I have two of them (primary and "locking") on each screw...

I suspect you might be doing something wrong, because two nuts locked together should not vibrate apart. I've done at least half a dozen of these things and never had this happen. You have to tighten the two nuts against each other (and tightly) or they'll loosen. I don't think the nylon insert in one of those locknuts will live long, as the PTO clutch gets hot from the friction of the belt and proximity to the muffler and engine.

I used your method to clean inside the holes but I used a .223 bore brush instead:biggrin2.gif: I soaked the holes again with kroil and still nothing, in my experience Kroil is the best penetrating oil on the market and still nothing so I used heat and they came right out alas I had to use a little force and patience, but they did finally come out. Thanks for the Tip. Now I have to figure out how this one part comes off the crank shaft, but i'll start a new thread so not to Hijack this one anymore.

The nuts for the pto's are made just for them so don't toss em.I think you can still get them from cub cadet.

Really? They look just like ordinary 1/4-28 jam nuts, which are what I've bought and used in there on several occasions.

It's the bolts that are special. But some times the pto can get hot Matt is right Nylocks won't work. You could use the all metal nuts but It's pretty rare that the IH system fails If properly torqued

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
