Figure 5-9. Conveyor Flight Wear Measurement
Installation
1. Using a suitable hoist capable of lifting at least 4000 lbs (1800 kg), lift rotating assembly from
cradle and lower onto base with pillow blocks in close alignment with mounting holes.
2. Use a brass hammer to fully seat alignment pins in bearing pillow blocks and base; do not
tighten nuts on alignment pins.
3. Orient Belleville washers with concave side down, and slide onto bolts. Insert bolts through
pillow block holes, and tighten in stages to torque specified in Hardware Torque
Specifications.
4. Install and tension drive belts between motor and bowl sheaves in accordance with Drive Belt
Replacement.
5. Insert spider into gearbox clutch half, and slide motor clutch half back into engagement with
gearbox half. Set gap between clutch halves at about 0.1875” to 0.250” (4.8mm to 6.4mm),
and tighten mounting screws in motor clutch half to 184 ft lbs (250Nm).
6. Install and secure belt guard over motor and bowl assembly sheaves.
7. Close case cover, and secure with screws, tightening from center of cover outward in both
directions.
8. If main bearings have been replaced, grease main bearings in accordance with lubrication
chart in Preventive Maintenance and the following steps:
a. Apply electric power, start centrifuge, and adjust bowl speed to 500RPM.
b. While watching bearing temperature, inject new grease into pillow block until grease flows
from the outlet port on the bottom half of the pillow block.
9. Connect feed piping to feed component flange.
10. Apply electric power, and start up centrifuge (refer to Section 4). Carefully monitor
performance, and check for any unusual noise.
