[woodbywallace]

Looking for any instructions on the best way to remove the flywheel so the oil seal could be replaced on rear seal. sure am learning a lot from this fantastic site. The info given here is great, and are highly appreciated Thanks so much Big John from Derry Pa

It would really help to know what motor you are working on. Always include anything you can about your tractor, motor and so on when asking for tech help.

T bar puller, harmonic balancer steering wheel pullers both work. a hammer and a big prybar works to but don't break the stub that the nut goes on off the crank if you use that method

There's threaded holes in the flywheel for puller bolts to go in, I believe they're 3/8 x 16 pitch. As Don said a T bar puller one of the ways. You can look in the K series manual in the tech section and there are pictures and listings of special service tools

T bar puller and a impact wrench work best, it can be done with a 1/2" breaker bar.

Few have a suitable puller, here's how I got the flywheel off my Kohler 14hp: Find a short 5/8 " NF bolt, also a nut to fit the same. Screw the nut onto your shaft using only half of the threads, then screw the bolt into the nut and tighten. This is what's called the poor man's 'knock-off' block, you then stick a sturdy screwdriver in behind the flywheel to put outward pressure on it, hit the end of the bolt with a good sized hammer. Mine came off on the second blow.
Pullers and special tools are best but this works quite well.
Also, welding the nut to the bolt at half threads makes a permanent 'knock-off' tool, I keep mine in the special tools box.

A puller is less likely to bend the end of the crank. Again, this way works, but it's easy to screw up the crank this way. A puller isn't expensive. Way less than a crankshaft.

You can get a puller like this.

I use a cheap $12 harmonic balance puller and a wack it with a rubber mallet. Never had one not come off yet.

I used a puller like oak has and just be careful to use the right bolt and correct thread and don't brake off the Bolt in the flywheel!!
