How do I get the main bolt out on top of the engine to expose the stator?? Its 15/16" and there seems to be no way to hold the flywheel....

Help! The grass want stop growing!!

Try finding a band style filter wrench, either rubber or belt type.

B & S did make a special wrench that went into the flywheel.

The only other idea I got is to get a pipe wrench onto the shaft in between the puleys under the motor.

Long before air and electric impacts were invented there were mechanics that knew how to impact a nut in instances like you are experiencing.

I don't give away many of my secrets :biggrin: but I feel the need at times when someone needing to repair a mower asks for help.

To Red Neck Impact - that nut you place your 15/16" box wrench on it and get the neighborhood kid to hold it in place so you can take a Mickey Mantle swing at it with a 2x4 about 2 ft. long. If it's a kid you like get him another 2x4 to hold the wrench down on the nut by pushing the end down on the nut/shaft.

If you don't have a neighbor kid, the wrench can be made to remain in place for impacting by shimming it with a cereal box top or other suitable household supplies etc.

If you have a cycle helmet with a face shield and an athletic cup I suggest wearing them.

I guarantee it will break free. I've never had this method fail. It even works on blade nuts and nuts on top of jack shaft sheaves.

I did not have a wrench that size so I used my 1/2" ratchit, had the wife hold it snug and hit using a 2x4. It was not a very hard hit either but the bolt came loose!

Excellent tip!!!! Thanks.

Now how do I get the flywheel off??

I ordered a puller but I rather get this job outa the way asap.
