Muffler
Remove the muffler by following these steps:
1. Remove the four screws (two on each side) that hold
the rear bumper in place using a 1/2” wrench.
See Figure 2.1.
2. Slide the bumper out from between the frame, the
fuel tank bracket on the right and utility bin bracket on
the left.
NOTE: The muffler guard will come off with the bumper.
3. Remove the two screws that hold each exhaust pipe
to the cylinder head using a T-27 torx driver.
See Figure 2.2.
4. Remove the muffler and exhaust pipes.
NOTE: The exhaust pipes are welded to the muffler. The
pipes and the muffler are serviced as one assem-
bly.
5. Clean and remove all gasket material from the cylin-
der head (and the exhaust pipe if they are being
reused).
6. Using new gaskets, install the muffler by following the
previous steps in reverse order.
NOTE: Tighten the exhaust screws to a torque of 150 in
lbs (17Nm).
NOTE: When installing the bumper, start all four screws
before tightening them. Otherwise the bumper will
bind and the holes will not line up.
7. Test drive the mower in a safe area before returning it
to service.
IMPORTANT: Do not put a mower with an exhaust leak
back in service.
