6.7 Tail
See Figure 29: General Arrangement, RLVAC Tail, Sheet 1 of 1 in Appendix 2: General Arrangement
Drawings for exploded views and part numbers.
Turn off and lock out the drive motor and the conveyor air supply (for pneumatic
takeup models) before removing guards or replacing any parts on the tail.
6.7.1 Tail Pulley Replacement
1. Relax belt tension on the conveying belt by loosening the takeup. See section 5.12.1 for screw
takeup drives or section 5.12.2 for pneumatic takeup drives.
2. If the tail pulley has an extended shaft and a PTO drive, remove the PTO drive guard and relax
belt tension on the PTO drive belt. See Figure 29: General Arrangement, RLVAC Tail, Sheet 1 of
1 for details.
3. If the tail pulley has an extended shaft and a PTO drive, remove the PTO timing pulley (38) and
taperlock bushing (39) following the removal procedure in the PCI bushing installation instruction
sheet.
4. Remove banded tail rollers (22) and the tail guard (34).
5. Unbolt the tail bearings (36) and lift the entire tail pulley assembly out of the conveyor.
6. Remove the tail bearings from the pulley.
Do not hammer or pry on the outer races of the bearings. Damage to the bearings may
result.
7. Install the tail bearings onto the new pulley. Do not tighten the set screws yet.
8. Verify the tail weldment is square to the frame by referencing the tail alignment guide seen in
Detail A of Figure 29: General Arrangement, RLVAC Tail, Sheet 1 of 1 in Appendix 2: General
Arrangement Drawings. The center square hole should align between the tail weldment and the
sideframe on both sides.
9. Slide the new pulley into place inside the loop of belt. Verify belt routing with Figure 10: Tail Belt
Routing in section 5.5.
10. Slide both bearings against their jack screws and snug the bearing bolts only until the bearings
can move with slight resistance.
11. Adjust the jack screws to set the tail pulley square to the frame. If a square is placed on the
sideframe, the leg of the square should touch the tail pulley in the exact center due to the pulley’s
crown.
12. Torque the bearing bolts. See Table 7: Fastener Standard Torque Values in section 6.3 for torque
values.
13. Ensure the pulley drum is centered between the bearings, then torque the bearing setscrews.
14. If the tail pulley has an extended shaft and a PTO drive, follow the reassembly procedure in
section 5.9 to reinstall the timing pulley.
15. Reinstall the guards and conveyor rollers that were removed.
16. Follow the belt tensioning and tracking procedures in section 5.12.1 for screw takeup drives, or
section 5.12.2 for pneumatic takeup drives.
6.7.2 Tail Snub Replacement
1. Relax belt tension on the conveying belt by loosening the takeup. See section 5.12.1 for screw
takeup drives or section 5.12.2 for pneumatic takeup drives.
