This procedure refers to either a VHS-type electric motor or hollow-shaft type gear drive.
1. If a driver support is furnished and not installed, perform these steps:
a) Hoist the driver support and inspect the mounting surfaces and register.
b) Clean these surfaces thoroughly.
c) Install the driver support on the discharge head and secure it with capscrews.
2. Inspect the driver:
a) Attach a sling to the lifting lugs of the driver and hoist the motor.
b) Inspect the mounting surface, register, and shaft extension.
c) Clean these surfaces thoroughly.
d) If any burrs are found, remove these burrs with a smooth mill file and thoroughly clean afterward.
3. Orient the motor-conduit box in the required position:
a) Align the motor-mounting holes with the mating-tapped holes on the discharge head.
b) Lower the motor until the registers engage and the motor rests on the discharge head.
c) Secure the motor with capscrews.
4. On drivers with a non-reverse ratchet or pins, manually turn the driver shaft clockwise when viewed
from the top, until the non-reverse ratchet or pins fully engage.
5. Lubricate the motor bearings according to the instructions on the lubrication plate attached to the
motor case.
6. Remove the drive coupling and hold-down bolts.
7. Screw the adjusting nut loosely onto the end of the drive shaft.
8. Clean the drive shaft thoroughly and attach a light line below the nut.
9. Lower the drive shaft through the motor-quill shaft and examine closely for dirt or burrs between the
shaft ends.
10. Raise the drive shaft and adjusting nut assembly to allow room to install the rigid-flanged coupling.
