    They aren't easy to get off most of the time.

    1) Is the engine still bolted down? If it isn't... then it will be almost impossible to get off.
    2) how are you holding the crank? I fill the PTO piston with rope.
    3) Most of the time, I use a 4' extension on my breaker bar.

    Engine is bolted
    Made a duct tape carpet stopper in the piston hole
    Used a huge pipe on my chain wrench didn't even fell like it budged.

    I heard you are not supposed to use heat b.c it could deto the engine seal on the PTO side.

    I use a heat gun to make things hot... but yes, you can damage the seal. BUT... sometimes you don't have a choice.

    One other thing to try... while you keep pressure on it.... have someone tap on the PTO with a metal hammer. Sometimes, the vibration will help break the rust/corrosion that is holding it on.

    I did an engine last year that I thought I was going to break the piston because I had to put so much pressure on the PTO. I had it out, and bolted to a bench... and when the PTO popped loose... I fell, and hurt myself. And... the way it popped... I thought I broke one of my table bolts. But, when I checked... it was the PTO.

    They can be very stubborn.

    If the splines aren't ripped out of the PTO, you may be better off using an impeller tool, since the chain wrench gets tighter, the harder you pull. (could be compressing on the threads)

    Get a can of kroil. Heat it up like Doc said then quench it with the kroil. let is set for a few hours and try it again while someone is rapping on the end of the PTO.

    99% of the time, no heat is needed. Use a large 18" pipe wrench(careful not to mash the grease zerk) with a 4' steel pipe on the end and put your weight into it, it will break loose and you can unscrew by hand. They are really tight.

    Forgot to mention the existing PTO is screwed the splines are toast so the impeller tool thing won't work. So if it doesn't matter if I destroy the PTO to get it off has anyone every just cut it until it came off.

    No, never cut into one because it isn't necessary. You shouldn't use the impeller tool to remove the pto anyway, it will strip or break, a large pipe wrench with an extended pipe on the end is the answer. Don't jerk it, just keep applying more and more steady force at the end of the 4' bar and it will break loose. It's a little tougher with motor in the ski because you can't literally lay on it and put your weight into it. So, be careful because when it breaks loose, you'll go flying.

    I will try the pipe wrench this weekend that sounds like it might work. And because I don't need the current PTO I will just trybto remove it this way.

    Finally got the PTO off but I did have to cut it off. I almost threw the wrench across the floor, I bought a pipe wrench and when I was attempting to remove it the pipe wrench actually broke....weak. But with patience and persistence I got the thing off and the new on.
