LUBRICATION
To avoid personal injury, always turn off engine/motor and wait for all motion to stop before making
adjustments or repairs.
DRUM SEAL PLATE ASSEMBLIES
Drum seals are provided on each end of the drum where the mixing shaft passes
through to the bearings. It is important to pump grease into the assemblies to
retain seal efficiency. Use enough grease to flush out old grease and carry away
any grit. Use lithium based grade 2 multi-purpose grease. See Figure 3.1
MIXING SHAFT BEARINGS
The mixing shaft bearings are permanently factory sealed and lubricated, and
should not require further service.
WHEEL BEARINGS
Wheel bearings should be packed once a year. Thoroughly clean old lubricant from the bearings, hub and spindles before
repacking. Pack bearings only one-half to two-thirds full with grease to prevent overheating. Use no. 2 wheel bearing grease.
DRUM SHAFT BEARING HANGERS
Drum yoke bearing hangers are located on each side of the drum, and are equipped with grease fittings. These bearings
should be lubricated once each week with lithium based grade 2 multi-purpose grease.
See Figure 3.1
ENGINE/MOTOR
Refer to the engine/motor operating instructions for all maintenance and lubrication instructions
and requirements.
DRIVE SHAFT BEARINGS
Pillow block style bearing are used on the drive shaft. See Drum Seal Plate Assemblies,
Lubrication Guidelines for more information.
