WARNING
This next step can be dangerous. The
snap ring is placed under tremendous tension
with the Truarc pliers while it is being
placed into the hub groove. Therefore, wear
SAFETY GLASSES and exercise care to
prevent the snap ring from slipping out of
the pliers. If the snap ring should slip out it
would travel with incredible speed and cause
personal injury if it struck a person.
4- Install the Truarc snap ring into the
groove of the forward gear hub.
5- Assemble the REVERSE gear by first
installing the nylon spacer into the cupped
end of the reverse bevel gear,
with its
key
ELECTROMATIC SHIFT 8-67
in the slot of the bevel gear. The spacer
MUST
be positioned to encircle the cupped
area in the opposite direction to the normal
winding of the spring coil. Install the spring
with the key indexed in the slot beside the
spacer key. Slide both keys against the side
of the slot they will pull against when
reverse gear is selected.
6- Coat three Allen-head cup-point
setscrews with Loctite,and then install
them to secure the spring to the bevel gear.
Tighten the setscrews in rotation, to a
torque value of 30-35 ln.vlbs., beginning
with the one nearest the spring. Bake the
assembly in a 300
0
oven for 1/2 hour. If an
oven is not available, apply Locquic Primer
"T" to the screws before tightening them,
and then allow them to cure for
'+
hours.
