SUSPENSIONS
FRONT FORK LUBRICATION
To replace the oil in the front fork legs, proceed
as follows:
• with the bike on the central stand, loosen the
side screw
"en
locking the steering head to the
fork arm; disconnect compensating pipe and
completely unscrew the hexagonal screw plug
«8,,; then undo drain plug "A ,,;
• slightly press the front part of the bike to
force out the plug
«
8 " which is solidal to the
shock absorber. Do this paying attention not to
damage the instruments panel ;
• refit plug " A" and introduce the quantity of
fluid necessary (60 cc Agip F. 1 ATF Dexron)
through the space existing between the inner
diameter of the fork and the shock absorber
body;
• release the front part of the bike refit plug
«8" and lock the side screw. Repeat the same
operation for the other fork leg ;
• reconnect compensating pipe and check
the pressures keeping to the given values.
OIL PNEUMATIC SHOCK ABSORBERS
The operating load pressures of these shock
ab~orbers
are the following ;
• front : 2 . . . ; . . . 3 kg/sqcm
• rear: 3 . . . ; . . . 5 kg/sqcm
To check the pressure it is advisable to use a
pressure gauge having a very short pipe (better
if any) , as the capacity of the pipe may affect the
pressure existing inside the shock absorbers.
To ascertain to which extent your pressure
gauge reduces, when taking the measurement,
the pressure inside the shock absorber it is suf-
ficient to carry out two consecutive measure-
ments: the difference between the two readings
gives approximately the pressure reduction oc-
curing whenever a measurement is taken.
The measurement must be taken with the bike
on the central stand and with cold shock ab-
sorbers; to charge the shock absorbers only
use moisture less air.
N.B. - Pressures gauges as above, are found on
the market: however it can be necessary to place
a
supplementary gasket in the gauge head, in or-
der that the valve stem inside the shock absorber
will be pressed only when the gasket has made
a
perfect tightening.
