mission. Use a piece of scotch tape to hold it in place.
15. Slide the brake rotor in place, shoulder out.

NOTE: A piece of scotch tape may be used to hold the
new brake pucks in place for assembly. The tape
will grind away when the brakes are applied.
See Figure 3.10.

small amount of releasable thread locking compound
such as Loctite® 242 (blue) to the mounting bolts and
tighten to a torque of 80 - 120 in lbs (9 - 13.5 Nm).

• With the brakes released, the mower should have electric motor drag when it is pushed.
NOTE: When the ignition key is “ON” the drag will be stiff. When the ignition key is “OFF” there will be very lit-
tle drag.
• With the brakes engaged, the wheels should slide before they rotate when the mower is pushed.
23. Test drive the mower in a safe area before returning it to service.
