LUBRICATION/ BOLT TORQUE
KEEP LUG NUTS PROPERLY TIGHTENED, CHECK NEW UNIT BEFORE OPERATION, CHECK AGAIN
AFTER 20-25 MILES (32-40 km) AND REGULARLY CHECK AT LEAST WEEKLY.
10 Lug Hubs (3/4” - 16 Studs) ....................................................450 - 500 ft.-lb. Torque (610 - 678 Nm)
(Torques per axle manufacturer specifications)
Before tightening bolts be sure you have the correct size bolt for the correct amount of torque.
Use only factory approved cutterhead components.
LUBRICATION
Then fully purge again before the machine is put back into operation. Failure to do this will ruin the bearings.
Bearings may corrode when the machine is setting idle.
The second largest cause of bearing failure is operating them at high speeds when the grease is cold. This causes
the bearing race to turn on the shaft. Naturally this ruins the bearing as well as the shaft. Allow the bearings to turn
at slower speeds for at least five minutes. Also check the bearing lock collar set screws for tightness each 30
days. A loose lock collar allows the sleeve to turn on the shaft. Failed bearings diagnosed as contamination or cold
starts at high speed are not covered by warranty or by the bearing manufacturer.
