The phonic wheel (1) is only removed if it has to be replaced.
To remove it, use a suitable lever.
Using the suitable tool 99370708 (1) and a vice, extract the
bearing (2), along with the related adjustment ring (3).
Wheel hub component check
!
Tool 99370700 (1) is used to safeguard the sleeve
thread.
Carefully clean all wheel hub components. Inspect
half-shafts, making sure they are not warped.
Inspect wheel clamping bolts: if the thread is
damaged, replace them. To extract the bolts, use a
vice.
The bearing rotation must be free and smooth.
Inspect the threads of wheel hub bearing
adjustment nuts and axle casing ends; if needed,
replace the nuts.
Replace all sealing elements with new ones.
