PTO shaft stuck

[tommu56]

I took one apart that was stubborn by drilling a hole in the back side of the female tube and tapping it 1/4-28 putting in a grease fitting and pumping it out with the grease gun.

I had one that was stuck on a old Post Hole Digger I bought. I looped a chain though one end and put a come along on the other end and some PB Blaster in it and strung it between two trees. After soaking overnight I gave the come along a few cranks and got it good and tight and smacked it a few times with a 4# sledge and she popped free.

See, that's the solution to most problems. A bigger hammer.
Had a similar situation, rototiller shaft stuck, soaked it in diesel, then PB blaster, tried heating it with a torch,tried tying it to a tree and pulling it, tried using a hydraulic ram, and what worked was taking it to my local tractor repair guy and paying him to do it!

I had the same problem. I disassembled the u-joint, put shaft in vice then drove out inside shaft with punch and large hammer. That was the easy part. 1 3/8 spline coupler was also rusted. Been soaking in oil for 3 days. I made a shaft with a 1/2 threaded perp. to shaft. Inserted shaft into u-joint holes then screwed in 1/2 bolt on to tiller splined shaft. Haven't got it loose yet but I got a lot of pressure on it? If anyone wants a picture of the setup let me know.

id just take the driveline off the tiller and hook one end to a tree and pull the other end with your tractor and pull them apart. easiest thing to do tho is just go buy new outer and inner tube and take yours off and put on new tube.

I did mine with a come-along and 2 trees. However I love Tommu56's solution of pumping full of grease and using hydrolic pressure to seperate the shafts.
