John Deere mower repair

[73fxe]

I've got a 255xl rider with a Kohler 15 horse motor. I am attempting to pull the flywheel to replace the stator. I've broken 2 cheep pullers, bought a better one and still can't get the flywheel to budge. I've snaped 2 puller bolts, 1 grade 5 and a grade 8 . I have been spraying penetrant on the shaft for 3 days, today I heated the area and melted wax down the shaft. Any other ideas?

pry bar under. Put the nut on a few threads. hit the shaft with nut on with good size hammer while pulling up on the pry bar. You can use heat with this method.

Also if you have a air hammer with a pointed chisel, use a pry bar under the flywheel.

I would heat with a puller installed. I would not beat or use a prybar, that is a good way to destroy bearings and break a case

Prybar / Crowbar. Put the nut back on so it’s about a 1/4” from the flywheel. Have to use a big hammer like 3# or more. Push down on the prybar and one swift whack and it should pop off. If you use a small hammer all you do is end up beating the end of the crankshaft and ruining the threads.

Aka the brute force method.

It usually works.

Put the puller on and tighten it up as much as you dare without breaking the bolts. Then take a hammer and smack the end of the puller hard. That always breaks them loose for me.

put your puller on and tighten. smack the flywheel on opposite sides at the same time with 2 hammers. careful not to damage magnets etc

I finally got back to the mower repair on sat. I used the puller, heat, then took 2 cold chisels under the flywheel to get it to come off. Replaced the stator, checked the output and got nothing. Started checking everything over and found the center line off the regulator was broken. At least the motor got a good cleaning. And it puts out 14.6 volts.

you don't hit it that hard and not with a sledgehammer!

It doesn't take much to break a diecast engine case in the wrong areas
