93. Install the pins (71) and the springs (62) (Fig. 17) in
their respective location on the input unit.
94. Smear the spools (44) and the springs (45) with
miscible grease. Fit and stick the spools in each
compartment of the cover (38), with the points
towards the unions (72) (Fig. 2). Slide and stick a
spring (45) in each spool.
95. On the external face of the cover (38), place three
sufficiently long and equally spaced studs in the
holes provided for screws (64).
96. Install and position the cover, with the valve port
(1) directed upwards (Fig. 18).
97. Before fitting screws (70), it is mandatory to
check that the spools (44) slide freely in each
compartment of the front cover on the input unit.
To do this, compress the springs (45), using a
screwdriver passed through the tapped holes of
the unions (72). If the springs cannot be
compressed, investigate the cause..
98. Pretighten screws (70).
99. During pretightening, check that the spools (44)
still slide freely. Also check that each end of the
(large) springs (62) is correctly housed in its respec-
tive seat.
100. Tighten screws (70) to a final torque of 36 - 46 Nm
(Fig. 12).
After completing the tightening, check again that
each spool can move freely and restore its initial
position.
I
MPORTANT: A spool valve blocked open can limit or
interrupt lubrication of the forward clutch when
operating.
101. It is mandatory to install and tighten the valve (1)
fitted with its seal to 6 - 8 Nm max. (Fig. 18). Fit
and tighten the unions (72).
102. Install the input unit (see section 5) and the
forward clutch (see § B).
