6.6. DRUM REMOVAL/MAINTENANCE
9000-00-0042 R3 85
8. Before reinstalling the drum, check the condition of the transition cone and the
aluminum inlet. Replace, if necessary.
9. Replace the inlet if it is badly worn down or otherwise damaged.
10. Check the foam seal on the front of the GrainVac body for damage. Replace, if
damaged.
Note: Time Saver: Slide a 4–5’ (1219 – 1524 mm) length of 1” (25.4 mm) standard pipe onto
the end of the drum shaft to use as a handle. This will simplify removal and make
alignment of the drum shaft to the rear bearing much easier on installation.
11. Reinstall the drum system and tighten in place. Ensure that the drum lip is 1/16” (1.6
mm) from inlet and doesn’t rub when drum is rotated.
Note: Be sure the spacers, washers, or snap rings are in place on the drum shaft, if required.
12. Align the pulleys on the belt drive using a straight edge. If a pulley needs to be
realigned, ensure that it is torqued to the specifications shown in Figure 6.11 when
reinstalling the hub.
13. Reinstall and tighten the drive belt.
14. Reinstall the front guard.
