16. Arm Restraints & Superstructure: Before
installing arms, install arm Restraint Gears as follows:
Install Restraint Gear into arm clevis, as shown in Fig. 17,
so that the rounded edge (top side) of the gear teeth is
facing upward. Then, install the (2) 3/8"-16NC x 1-1/2"
HHCS (8 total for all 4 arms) and 3/8" Spring
Lockwashers into the gear and arm as illustrated Fig. 17,
but do not tighten.
After installing Restraint Gears, raise carriages to a
convenient height. Grease swivel arm pins and holes with
Lithium grease. Raise Gear Block by pulling upward on
pin-ring to allow enough clearance for the Restraint Gear
and arm to slide into the yoke clevis and under the teeth
of the Gear Block, Fig. 18. Install 1-1/2" diameter arm
pin(s) and 3/16" x 2" cotter pin(s), Fig. 19. After
installing arm pin, torque the two Restraint Gear bolts to
30-34 ft.-lbs. Let the Gear Block down allowing the teeth
of the Restraint Gear and Gear Block to mesh together,
Fig. 18.
17. Oil Filling & Bleeding: Use Dexron III ATF, or
Hydraulic Fluid that meets ISO 32 specifications.
