help with my craftsman mower

[[email protected]]

I need instructions or a forum showing how to remove and replace the flywheel ring gear in my B&S motor model 28M707. This is the motor in my riding motor.

I have replaced ring gears on tractor engines, not lawnmowers.

They are an interference fit. You have to destroy the old one to get it off the flywheel.

Heat the new one with oxy-acetylene torch enough for it to drop on the flywheel. Nowhere near 'red' hot. If it doesn't drop exactly into place, use a hammer and punch to seat it. You only have a few seconds to do this.

Welcome to the forum!

I'm going to move this thread over to our Briggs & Stratton small engine section.

If its a 28M707 it should be a aluminum ring-gear and hold on by screws and the part number I believe is 696537.

Thanks for your reply - The part number is correct - now I must figure out how the get to it without messing up everything!

You have to take the flywheel off.
The screws tend to rust in solid.
