WHEEL BEARING LUBRICATION
Tapered type hub cap
Taper roller bearings and deep groove ball
bearing
Axles fitted with taper roller bearings are
recognizable by a tapered type hub cap, see Figure.
Remove wheels and wheel hubs.
Mark dismounted wheel hubs and bearing races so
that their identity is not mistaken during reassembly.
Clean wheel hubs thoroughly inside and outside.
Remove old grease totally.
Clean taper roller bearings and seals (using diesel oil)
and check for reuseability.
Work BPW special longlife grease ECO_Li 91 into
the cavities between the taper roller and cage. Smear
grease into the hub's outer bearing race.
Greasing bearing race
Fill the hub caps to 3/4 full with grease.
Fit wheel hubs, adjust the bearing play and fit the hub
caps.
Cylindrical hub cap shape
Compact bearings
Compact bearings are recognizable by cylindrical hub
cap shape, see Figure.
Compact bearings are maintenance-free due to
permanent lubrication and are designed for high
mileages.
Therefore, there is no grease change or regreasing
necessary.
