24 Swingarm and suspension
bearings (TDM and TRX
models) - re-greasing
1 Over a period of time the grease will harden or
dirt will penetrate the bearings due to failed dust
seals. Unlike the XTZ, these models are not
equipped with grease nipples
2 Remove the swingarm as described in
Chapter 6 for greasing of the bearings.
3 On TRX models, the suspension linkage is
22.6b ... and remove the cover and filter
22.7c ... and fit the cover onto the engine
8 Refill the oil tank to the proper level using the
recommended type and amount of oil (see Daily
(pre-ride) checks and
Specifications). With the motorcycle vertical, the
oil level should lie between the maximum and
minimum level lines on the dipstick or inspection
window (according to model) (see Daily (pre-ride)
checks). Install the filler cap. Start the engine and
let it run for two or three minutes. It is advisable
to perform an oil pressure check (see Section
32). Stop the engine, wait a few minutes, then
check the oil level. If necessary, add more oil to
bring the

25 Steering head bearings -
lubrication
1 Over a period of time the grease will harden or
may be washed out of the bearings by incorrect
use of jet washes.
22.7a Fit the new O-rings (arrowed)...
level up to the maximum level line on the dipstick
or window. Check around the drain plugs for
leaks.
9 The old oil drained from the engine cannot be
re-used and should be disposed of properly.
Check with your local refuse disposal company,
disposal facility or environmental agency to see
whether they will accept the used oil for
recycling. Don't pour used oil into drains or onto
the ground - see Haynes Hint and UK's safe oil
disposal contact in Section 7.
23 Fuel filter - renewal (1999
TDM models)
1 The fuel filter should be renewed periodically.
To do so, loosen the hose clamps and slide them
this Chapter's
down the hoses, away from the filter. Pry the
hoses off each end of the filter and connect a
new filter in its place (see illustration 15.12 in
Chapter 4); fuel filters usually have an arrow on
their body indicating the direction of fuel flow.
2 Check that there is no sign of leakage from the
fuel pump. Check that the fuel pump hose
connections are secure.
2 Disassemble the steering head for re-greasing
of the bearings. Refer to Chapter 6 for details.
