Engine Mounting Question.
 

I have a five year old Pro Z with a 27 hp Kawasaki on it. Mowing last Thursday and the mower stopped moving so I looked under the machine and the hydro drive belt was shredded. Local dealer had one so I picked it up Friday to install on Saturday. While install the belt the engine moved. Started looking and 3 out of the 4 mounting bolts were broke of and the 4th was loose. Has anyone else seen this? Wondering about the design of mounting the engine directly to the frame without any dampeners. Also wondering if anyone had retrofitted some kind of urethane mounts and how you dealt with the pulley alignment issue.

Thanks

Not familiar with your lawnmower, but before I'd try reengineering the motor mounting system I'd replace the broken bolts with grade 8's instead of "lowest cost supplier" situation that manufactures require to save costs.

You can get good bolts at a place like tractor supply and they are inexpensive, and sold by the pound, just make sure they are grade 8.
Have fun! :beerchug:

Agree with grade 8 but also consider some locking configuration such as lock washers, serrated heads and/or maybe a dab of blue lock tite. Vibrations can shake 'em loose.

Does it require bolts AND nuts?
If so, use Stover nuts and a flat washer.

I'm fearful the bolts are broken off in the motor casting.
Most cheap stuff today use cast holes (no machining) then self taping bolts.
its a cost saving but a pain in the ass when they break off.':angry:
