Changing grease in the wheel hub bearing
- every 1000 operating hours
- annually at the latest
• Jack vehicle up securely and release brakes.
• Remove wheels and dust caps.
• Remove split pin and unscrew the axle nut.
• Using a suitable puller, remove the wheel hub with
brake drum, tapered roller bearing as well as seals
from the steering knuckle.
• Remove wheel hub and bearing cage markers so
that they won’t be transposed when assembling.
• Clean the brakes and check for wear, soundness
and function, and replace worn parts.
Inside the brake must be kept free of grease and
impurities.
• Thoroughly clean the wheel hubs inside and outside.
Remove old grease completely. Thoroughly clean
bearing and seals (diesel) and check if reusable.
• In assembling the bearing lightly grease the
bearing seats and assemble all parts in reverse
order. Carefull fasten parts to press fit with tubular
bearing bushes without jamming or damaging.
• Before assembling, coat the bearing, the wheel
hub cavity as well as the dust cap with grease. The
amount of grease used should approximately fill
a quarter to a third of the free space of the fitted
hub.
• Fit the axle nut, and carry out bearing adjustment
as well as brake adjustment.
• Finally, check the function and carry out a relevant
test run and eliminate possible determined
defects.
