2.4.2 Worm Gear Drive Assembly Replacement Procedure
Worm Gear Drive Assembly Replacement Procedure
After installing the new worm gear drive, snug the four mounting screws holding the gearbox in place.
The screws must be snug enough to position the gearbox against the mounting bracket while allowing
a limited freedom of motion for the gearbox.
► (1) Check that the motor drive shaft coupling screws and both shaft collar screws are loose.
► See figure "Worm Gear Assembly".
► (2) Verify that the coupling is completely disconnected from the coupling adaptor (see figure "Worm
Gear Assembly").
► Verify that both of the elevator lift bars have full and equal freedom of motion (any signi fi cant drag
can result in gearbox failure).
This is a two-step process:
Worm Gear Assembly
1. Slip clutch
2. Motor drive shaft coupling screw use wrench: 3/32
hex key
3. Worm gear mounting screws use wrench: 7/64” hex
key driver
4. Coupling
5. Shaft collar screws use wrench: 3/32” hex key driver
6. Coupling adapter
