11.4 Slacken the clamp bolt (A) and unscrew the axle (B)
On 1999 TDM models, trace the wiring from the
speedometer drive gear up to its 3-pin connector
and disconnect it, then free the wiring from the
clips which retain it to the brake hose;
alternatively, leave the wiring attached so that as
the wheel is removed the drive gear is left joined
to its lead.
4 On TDM and TRX models, slacken the axle
clamp bolt on the bottom of the right-hand fork,
then unscrew the axle (see illustration).
5 On XTZ models, first remove the screws
securing the disc covers and remove the covers
(see illustration). Remove the split pin from the
end of the axle, then unscrew the axle nut and
remove the washer. Counter-hold the axle head
to prevent it turning if necessary. Discard the split
pin as a new one should be used.
6 Support the wheel, then withdraw the axle
from the right-hand side and carefully lower the
wheel. Use a drift to drive out the axle if required.
7 Remove the spacer from the right-hand side of
the wheel and the speedometer drive gear from
the left-hand side, noting how they fit (see
illustrations).
Caution: Don't lay the wheel down and allow
it to rest on a disc - the disc could become
warped. Set the wheel on wood blocks so the
disc doesn't support the weight of the wheel,
or keep it upright

8 Check the axle for straightness by rolling it on
a flat surface such as a piece of plate glass (first
wipe off all old grease and remove any corrosion
using fine emery cloth). If the axle is bent, renew
it.
9 Check the condition of the wheel bearings
(see Section 13).

12 Lift the wheel into place between the fork
sliders, making sure the spacer and drive gear
remain in position, and that the slot in the drive
gear locates over the tab on the inside of the fork
(see illustration). Slide the axle in from the right-
hand side (see illustration).

to the torque setting specified at the beginning of
the Chapter (see illustration).
