Help can’t get pto off I have tried everything engine is completely torn down

Spray it with WD40 get you a big pulley puller three year wrap around it tighten it down nice and snug take a hammer and gently tap on the end of your puller don't get carried away with it snug it down a little more tap some more spray again with WD-40 tighten it down tap a little more and continue this process until it pops off this is what worked for me I'm not stuck and nothing else would work so hopefully you have the same luck hope this helps

It's threaded on. Easier to do with the engine in one piece and mounted in the seadoo. Block off one piston so the engine does not turn and get a long breaker bar, heat the PTO and then give it a go.

Alternatively I have heard some crank rebuild places will remove it for you if you can't get it off. But off the top I am not sure which ones.

Actually due to the engine layout vs hull opening the pto may not be accessable mounted in the ski. When I removed mine I mounted the engine to a bunch of long 2x4's so i could use a long breaker bar on it and put enought pressure on it without the engine flipping over. You might need to do something like that. But it will mean putting your engine back together. Just use the old parts and you only need 1 cylinder back on to stop the engine from turning over.

I have been using Spider’s method for years, First I use the rope in the cylinder method to block off the piston. Then I use a 3 pin puller, I use an impact gun and apply pressure to the puller, as much as it can apply,,then I apply the torch,,,I will repeat the process,,,apply the gun,,,apply heat until it pops off…the loktite has to be heated enough until it melts,,,usually,,,this method works like butter.

CRC Freeze-Off works well and so does a Torch.

I get them Louisiana/Mississippi engines some are downright miserable. I have a large table vise and a cutting torch and the Cutting torch does not heat the PTO up quick enough. That is the key, A quick heat. I also use an impact which some people don't recommend. The part has the be held very rigid. People might be surprised at how much heat it takes to get the threads of the PTO hot. You could put the crank in an oven to 500 degrees but you're wife will likely kill you. If you don't have the correct equipment it is a daunting task.

I wish you lived close to me.... some are more ornery than others but "all them beyotchs succumb !!"

According to the Loktite web site,,,the heat must be hot enough an long enough to melt the thread locker.

I have to remove before I pull the motor apart, I mount the block to some Uni-strut so I can secure the motor while I use my breaker bar with a 8'stick of 2" conduit as a "helper" on my breaker bar. Usually breaks free with that much leverage. sounds extreme but that is what I have found that works for the 787 and 717. The 947 I have has a bolt on PTO which I found out about the hard way after breaking my breaker bar.

when I had to remove the PTO from my 787 cranck it was frozen solid.
I ended up clamping the crankshaft web in a big vise with coper plates beteween the web and the jaws to avoid any marking. Then i made a "wrench" with a 2meter long steel square tube that bolts to the 2 holes next to the splines.
still heating as much as i could with a propane torch, it finaly came off but it was very stressfull

Throw the crank in the freezer number 1.number two get a few 2x4 .3 get a torch that can heat it up fast.then after a overnight freeze put crank web in between 2x4 drive your front of car on it to use as a vice carefully and quickly have someone help.fast heat is the key

Some older sage mechanics like ”pressure/torque”..”heat”,,.”shock”…and then “ice”
