REAR SUSPENSION
Prepare the diaphragm with assembled OR (we advise using a new one for each
replacement). Fill up the reservoir with oil and insert the diaphragm into the reservoir,
(see photo).
Quickly push the diaphragm downwards at the bottom of the reservoir holding fast
the forkdìrod in the topping up position. The oil topped up in the reservoir is
transferred into the shock absorber body, then sifting through the position blades,
it reaches the required level. Avoid possible air intake by quickly carrying out these
operations.
Proceed by topping up until reachin approx. 2 cms (0.8 in.) from the body edge.
Then, execute 4 or 5 alternating strokes of 5 - 6 cms (2-2.4 in.) to bleed the air left
under the piston unit.
These movements should be slow to prevent the reservoir diaphragm
from moving through cavitation or compression. Top up with oil the
smap ring throat is reached, then slowly fit the forkrod, and the inside
end-of-stroke pad, edge-wise with the snap ring throat.
Keep the forkrod in position and run the forkrod guide to fit the shock absorber tube.
Drive the forkrod guide inside the body antil the snap ring housing is free. Insert the
snap ring and tighten it in position. Pull the rokrod upwards to take the forkrod guide
in working position.
