Flywheel Brake Adjustments
(104700)
The flywhe el brake system is part of a safety
control mechanism required by some equipment
applications. When the operator releases an
equip ment control (bail) with the engine running
at the
FAST
selection, the flywheel brake must
stop the engine within 3 seconds.
Using torque wrench
#19393
and a socket to fit
the flywheel nut, turn the flywheel clockwise
(CW) with the brake enga ged. Turning at a
steady rate, the torque reading should be the
listed value.
SEE SECTION 14- ENGINE
SPECIFICA TIONS.
If the reading is low:
• Check the thickness of the brake pad.
• Replace brake lever and pad if the brake
pad thickness is less than
0.090 in.
(2.29mm)
.
If the pad is within specification:
• Adjust the control cable casing anchor to
position the pad closer to the flywheel
when the safety control is in
RUN
.
If correct adjustment cannot be made:
• Replace the brake assembly.
