MAINTENANCE
Frame
• Hub Bearings: Check hub bearings for
restriction, noise or abnormal play in rotation.
Bearings must absolutely be replaced if they
present a defect.
CAUTION: If a hub bearing shows a defect, replace
the both hub bearings and replace hub bearings
on all 4 Track Systems at the same time.
• Hub Bearing seal: The maintenance chart
recommends cleaning and lubricating the hub
seal. Refer to “Lubrication” in the Maintenance
section on page 22.
NOTE: Lubrication done at the recommended
intervals allows the hub seal to maintain
optimal sealing action and prolongs the life
span of the hub bearings.
• Track Guide wear: Check wear on Track
guides. Replace guides if wear is too great.
Refer to “Wear” in the Maintenance section on
page 25.
• Stabilizers
: Verify condition of rubber cones
on the stabilizer assembly of front systems and
wheel axle assembly of rear systems. If the
cone bores show oval-shaped wear, they must
be replaced. Refer to the “Wear” section in the
User Manual on page 25.
• Cracks
: Visually inspect frames for presence
of cracks or defects that can impair proper
operation of the Track System. Replace
components if damaged.
Sprockets
• Wear: Check wear of sprockets on the
Systems. Replace if wear is too great. Refer to
“Wear” in the Maintenance section on page 26.
Anti-rotation
• Lubrication: The maintenance chart
recommends cleaning and lubricating the anti-
rotation arms. Refer to “Lubrication” in the
Maintenance section on page 23.
• Bolt Torque
: Verify torque of assembly bolts
on anchor brackets and anti-rotation arms at
the recommended intervals specified by the
maintenance chart.
• Cracked or bent parts
: Visually inspect anti-
rotation arms for presence of cracked or bent
parts that can impair proper functioning.
Replace components if damaged.
• Rubber Dampers
: Verify condition of rubber
dampers on anti–rotation arms. Replace
dampers if they are deformed, cracked or show
severe wear. Refer to “Wear” in the
Maintenance section on page 24.
CAUTION: When pressure washing the Track
System, care must be taken to keep the water
stream away from wheel and hub bearing seals
and from rubber caps.
