WHEEL BEARING ADJUSTMENT
Bearing play
Jack up the compressor, release brakes.
Turn wheels manually and rock.
If any bearing play is perceivable, adjust the bearings.
Compact bearings
Compact bearings are recognizable by their
cylindrical hub cap shape.
Conventional taper roller bearings
Taper roller bearings are recognisable by the conical
profile of the hub cap.
• Lever off hub cap. Remove split pin from axle nut
and tighten so that rotation of the wheel is slightly
braked.
• Turn back the axle nut to the next possible split pin
hole, by a maximum of 30 degrees.
• Insert split pin and bend ends slightly outwards.
• Check wheel rotation, fit hub cap.
Important:
The grease in the hub cap and bearing must not be
contaminated with dirt during this job!
WHEEL BOLTS CHECK
Wheel bolts tightening
Tighten wheel bolts crosswise using a torque wrench

Tightening torques of wheel bolts
