Assembly
1. The front and back worm retainers (keys 48
and 49) each have a slot in their threads for a set
screw (key 52). Pack the ball bearings (key 50) with
lithium grease, and insert one ball bearing into the
back worm retainer (key 48).
2. Thread the back worm retainer and ball bearing
into the gear case. Align the slot in the worm retainer
with the set screw hole in the gear case, insert the
set screw (key 52), and tighten.
3. Coat the worm shaft (key 51) threads with lithium
grease lubricant, and slide the shaft into the gear
case so that the end of the shaft fits snugly in the
back worm retainer.
4. Insert the bearing into the front worm retainer
(key 49), and thread the retainer and ball bearing
into the gear case. Align the slot in the retainer with
the hole in the gear case, insert the set screw
(key 52), and tighten.
5. Slide the handwheel onto the worm shaft
(key 51), and install the retaining ring (key 60).
6. Pack the two thrust bearings (key 43) with lithium
grease lubricant. Install one thrust bearing, then the
worm gear (key 44), followed by the second thrust
bearing and the bearing and gear retainer (key 45).
7. Coat the power screw threads (key 46) with
lithium grease lubricant. Slide the power screw into
the thrust bearing (key 43), turn the handwheel, and
feed the sleeve through the worm gear.
8. Install the gear case cover (key 53), and tighten
the cap screws (key 54).
9. Adjust the set screws (key 55) to eliminate free
play in the bearings.
Note
Overtightening the set screws (key 55)
will make handwheel operation
difficult.
