TE9000 / 93000 Service
FITTING OF THE SENSOR
Assemble the spring bush (21213036) into the sensor mounting block
(22221063) (fig. 23). Lightly grease the sensor assembly and push fully
into the mounting block. When the hub is refitted the pole wheel will push
the sensor back and thus obtain the correct clearance.
The mounting block is fixed to the beam using a screw (21221521)
tightened to 25/35 Nm. During tightening of the screw move the block
from side to side so that it is correctly seated and is within ±2.5° to the
wheel axis. The sensor assembly may be rotated in the mounting block to
allow the cable to pass either side of the anchor bracket. Pass the sensor
cable through the dust cover using the uppermost hole and fit grommet
(21220842).
SENSOR OUTPUT
Connect the output cable to a suitable multimeter. Rotate the hub by hand
at a constant rate of approximately 30 rpm and note the maximum and
minimum readings. The minimum voltage reading should be 400
millivolts and the ratio of max/min should not exceed 2. If either values
are not obtained check the installed air gap between the sensor and pole
wheel does not exceed 0.7mm and the pole wheel runout does not exceed
0.2mm. If the installation is not correct contact the supplier of the anti-
lock equipment for further advice.
REMOVAL AND REFITTING OF DUST COVERS
Normally most service operations can be carried out with dust covers in
place. If for any reason they must be replaced unfasten the 4 screws at
each wheel end securing the dust cover using an M13 socket (fig. 24) and
remove the two halves of each dust cover. When refitting ensure that the
halves are pushed together and locating tabs correctly engaged to ensure
any gaps are minimised before tightening the screws to 50/60 Nm.

FITTING OF A HUBODOMETER
The TE axle may be fitted with an hubodometer by using either a special
hub cap or additional mounting strap. It is not possible to fit an
hubodometer to a standard hub cap and attempting to do so may cause
damage to the spindle or the sealing of the hub cavity.
For hubodometer types up to 85mm outside diameter, use special hub
cap (21221060).
