13.5.2 Procedure
Always follow the proper shutdown procedure
(Section 8.2 or 8.3) before performing any
maintenance on the Rotofilter.
1. Pump grease through the grease fitting using
the grease gun. Grease should be applied until it
discharges from the bearing seals to ensure no
dirt or water is present.
2. Clean the threads on the axle and the two
mounting bolts and apply anti-seizing compound.
3. Place a new wheel onto the assembly.
4. Grease the assembly through the grease fitting
until grease is forced out around the axle.
5. Apply anti-seizing compound to all
stainless fasteners.
6. Place the support wheel assembly onto the
tapped flat bar on the bridge. Thread in both
bolts and hand-tighten.
7. Align the axle support plate to the location line
penciled on the tapped flat bar. Tighten both
bolts with a torque wrench.
8. Repeat the previous section, then this section,
for the other support wheel assembly.
9. Lower the hydraulic jack until the drum rests on
the support wheels. Remove the jack and any
other tools or parts.
10. Follow the Startup procedures in Section 8.2.
11. Ensure that all wheels turn smoothly.
