remove the oil seal installer. Note that it may be necessary
to gently tap the end of the shaft to release the installer.
Fig 9.
Reassemble tool B and continue pulling the axle shaft into
position by tightening stud C to preload the bearings.
Rotate the shaft during this process to seat the bearings.
Tighten stud C to 80 Nm (59 lbf ft, 8.2 kgf m). Rotate the
axle shaft 5 full revolutions to ensure that the bearings are
fully seated then recheck and, if necessary, tighten stud C
further to 80 Nm (59 lbf ft, 8.2 kgf m). Continue rotating the
shaft until the stud requires no further retightening.
Position a dial gauge against the flat face of the sprocket
as shown at D and zero the gauge. Reposition the dial
gauge onto the end of the axle shaft as shown at E and
note the reading. Remove the gauge and assembly tool.
Preload washer 3 is available in various thicknesses to
allow for the correct preload of bearings 9 and 10 as
follows:
Select the preload washer which gives the closest match
to the dial gauge reading.
Assemble the preload washer 3 onto the axle shaft with the
stepped face towards the shaft (part numbered face away
from the shaft). Fit washer 2 and bolt 1. Progressively
tighten bolt 1 to 220 Nm (162 lbf ft, 22.4 kgf m) whilst
rotating the shaft to seat the bearings.
Check that the hub rotates freely by hand.
To fit the drive chain it is necessary to remove the sprocket.
Fit the chain around the sprocket and also the motor
sprocket. Refit the sprocket and washers making sure that
the stepped face of preload washer 3 is towards the shaft.
Retighten bolt 1 to 220 Nm (162 lbf ft, 22.4 kgf m).
