SCREW CONVEYOR DRIVE
The TL screw conveyor drive consists of a component gear drive
(which equals the TR gear drive plus the gear drive adaptor and minus the torque
arm assembly), a drive shaft kit and a trough end adaptor kit.
To convert a TR to a TL, a TR/TL conversion kit, along with a drive shaft kit
and tround end adaptor kit is required.
The TL drive shaft kit contains a removable shaft, locknut, lockwasher and key.
TL drive shafts have a tapered output end to avoid binding.
The trough end adaptor kit contains the trough end adaptor and packing gland
assembly. Dorris trough ends are available.

TROUGH END ADAPTORS
All dimensions are typical.
All trough end adaptors can use either the standard or high performance packing
gland assembly.
C69 adaptor uses 1-1/2 inch drive shaft; C924 adaptor uses 2 through 3-716 inch
drive shaft.
MOTOR MOUNTS (2MM - 90 LBS.)
Motor brackets are shown in the intermediate position. The brackets can
be raised or lowered 6 1/4 inches to the high or low position by moving
to the next set of mounting holes.
The motor brackets can be mounted on either the long (6 o'clock) or short (3
o'clock) sides of the housing.
Consult factory for trough end clearances
for the other motor mounting positions not shown.
