DISC BRAKE MAINTENANCE
(310-2400 Only)
1. Remove the brake return spring, and then
the cotter pin securing the brake castle nut.
2. Insert a 0.020" (0.5 mm) feeler gage be-
tween the brake rotor and outer brake fric-
tion stator, and then set the brake by tight-

FRICTION PACK ADJUSTMENT
The friction pack dampens or holds the opera-
tor control lever in its desired position.
Adjustment for the amount of drag or holding
force can be made by turning the friction pack
nut in or out.
Adjustments should be made in no more than
1/4 turn increments.
Over-tightening will result in difficulty or inability
of the operator to move the control lever.
Note: The factory setting for the friction pack is
assembly of the nut to 100 in-lbs (11 Nm)
torque. The friction pack nut is then backed off
per vehicle manufacturer’s specifications.
