Conveyor Drive Assembly
Refer to Fig. 14. The conveyor
drive assembly is made up of a
crank assembly, a clutch assembly,
gear reducer, and 1/4 HP motor.
Crank Assembly –
Refer to Fig. 13. The crank
assembly mounts inside the dish-
washer hood and is made up of a
crank, adjustable stud, and cross-
head roller. The roller engages the
conveyor cradle assembly. The
crank assembly rotates in a counter-
clockwise direction. The crosshead
roller should be adjusted so that
it is flush with the bottom of the
cradle assembly crosshead.
Clutch Assembly –
Refer to Fig.14. The clutch assembly
is made up of the clutch discs, a clutch
shaft, bearing, bearing housing, and
seal assembly. The clutch assembly
couples the output shaft of the gear
reducer to the crank assembly.
Clutch Adjustment –
The clutch assembly is torqued at the
factory to 12 ft/lbs. This allows the
clutch to slip if the conveyor cradle
assembly jams.
Refer to Fig. 17.
To adjust the clutch:
1. Loosen the two set screws
in the clutch adjusting nut.
2. Tighten the adjusting nut only
enough so that the clutch
assembly will slip when a
person of moderate build (about
180lbs./82 kg) exerts force against
the conveyor cradle assembly.
3. It is extremely important that the
clutch assembly slips if the conveyor
cradle jams; so be careful not to
overtighten the clutch adjusting nut.
4. Tighten the set screws in the adjust-
ing nut and recheck the conveyor
cradle assembly.
