Small Engines (Lawn Mowers, etc.): Snowthrower flywheel removal, john deere model, air hammer

Question
Hello,

I have a John Deere model 726 snowthrower. I need to get the flywheel off to repair a broken wire behind it.  I am not sure of the proper procedure for removal or what type of wheel puller should be used, if any.    

Thanks in advance for your help.

Hi Joe,

Here is my flywheel proceedure:
The flywheels' bore is tapered and mates with the tapered crankshaft.  A nut secures it.  The recommended way to remove a flywheel is to use a puller.  An alternative, is to tap on the crankshaft top, with a brass hammer or use a punch tip on an air
hammer.   The flywheel will need to be held up and supported or upward pressure applied with 2 large prybars. (A 2 person job.) Care is needed so the flywheel doesn't crack or bend.  Also be careful to not mushroom over
the crankshaft top.  After doing what you need to do, re-install the flywheel after cleaning the tapers and re-tighten the nut to 65 ft/lbs.

Let me know how you make out.
Michael
