Generolly, the reossembly
p'rocedure
depends
on the extent, to wlrich the unit hos been token
oport. For betterunderstonding,
we sholl des-
cribe the procedure
ond peculieorities
of reos-
sembly of o completely
disossembled unit.
Gear Chonge Mechonism
. 1.
Clomp the right-hond holf of the housing
(when viewed from the flonge securing
it to
the engine) in the MP 9-101 stond
com-
plemented with the MP 3-101 georbox
rock, ond
check the housing for completeness.
2. Instoll
circlips on the striking fork rods
of
the reverse
ond 1st ond 2nd speed. The ring
with the lower
nose is to be fitted
on the 1st--
ond 2nd-speed rods.
3. lnsert the reverse speed
striking fork rod
into the housing
so thot the inserted
end pro-
trudes slightly from its guide,
slip on it the
striking fork with the longer
side of its heod
first,- ond push
the striking fork rod through
the fork
ond the end of the guide
os for os=it

into the free holes for
striking fork rods (both pins
of the
iig), ond
proceeding through the hole in its side ond
using o stick or o length of wire, push
the lock
pin into the housing
os for os it will go.
Proceed
in the some monner for
inserting the next pin
(use one pirr
of the

ond on
olmost immediote clutch disengogement. Access
to the releose
cylinder con be goined
os de-
scribed in the previous porogroph
on clutch
lubricotion. Hold the rod protruding from
the
relose cylinder ond force
from it corefully the
releose lever, ogoinst which it is restingi
the
lever con be relieved by disengoging the ten-
sion (pull-off
) springs.
ln service, the forcing-off
must be ot leost
2 mm. Adiust it to 4
to 5 mm by odiusting the
length of the rod. After hoving
loosened the nut
on the rod
of the releose cylinder, rotote
the
releose finger to obtoin the correct rod
length.
Then retighten the nut, thus locking the releose
f inger in its position
on the rod.
lf the ploy
is correctly od justed,
the f ree
trovel of the
clutch pedol
pod should ronge
from 40 to 50 mm. lt should not be ollowed to
drop below '!0
to 15 mm. lf the described od-
justing procedure foils to bring the required
result, it is necessory to odjust the clutch
mech-
onism in occordonce with
informotion con
toined in Chopter 3.2.
Bleeding the Glutch Hydroulic System
The movement of the clutch pedol
is trons-
mitted hydroulicolly to the clutch releose cylin-
der. The couses ond symptoms of penetrotion

After hoving topped up the oil,
woit obout 2 minutes (while
