15. Arm Restraints & Superstructure: Before install-
ing arms, install arm Restraint Gears as follows: Install
Restraint Gear onto arm clevis, as shown in Fig. 18, so
that the rounded edge (top side) of the gear teeth is fac-
ing upward. Then, install the three (3) 3/8"-16NC x 1
1/2" Lg. HHCS (12 total for all 4 arms) and 3/8" Spring
Lockwashers into the gear and arm as illustrated Fig. 18,
but do not tighten. After installing Restraint Gears, raise
carriage to a convenient height. Grease swivel arm pins
and holes with Lithium grease, Fig. 20. Raise Gear Block

for the Restraint Gear and arm to slide over the yoke and
under the teeth of the Gear Block (or gear stop), Fig. 19.
Install 1-3/4" diameter arm pin(s) and 3/16" x 2-1/4" cotter
