bolts (nuts).
Maintenance
10,000 km or 3 years later:
• Check the wheel bearing axial clearance and
adjust if necessary.

Operation
Check the axle wheel bearing axial clearance:
Steps:
• Jacking trailer, check whether the wheels turn
smoothly, without hindrance.
• Axial flipping tires, whether we can feel the
obvious gap
Re-adjust the axle hub bearing axial
clearance:
Steps:
• Remove the wheels and wheel covers.
• Remove the slotted nut cotter pin.
• Tighten shaft nut, then back to loose 1/2 turn (180
°), then tighten 1/4 turn (90 °).
• Check the wheel functioning - is free to rotate, and
the wheel can not be detected with axial clearance.
• Plug cotter pin.
Note:
The bearing clearance adjustment too tight
can cause bearing damage.
• check the quality and quantity of grease, if
necessary, the filling or replacement of grease.
Wheel Bearing Grease: 2 # of lithium grease.
