6. Using a torque wrench and socket to fit the
flywheel nut, turn flywheel clockwise with
brake engaged. While turning at a steady
rate, torque reading should be 26 lb.-in.
(3 Nm) or higher.
7. If reading is low, check thickness of brake
pad. Replace brake assembly if thickness
is less than 0.09” (2.28mm).
8. If brake pad thickness is acceptable,
adjust control cable to position pad closer
to flywheel when safety control is in RUN
