c) CONTROL OF ASSEMBLY OF REACTION
SPRING
For a correct functioning of the rockshaft the top
link bracket, when it is not working, must not
have an axial play in the positive and negative.
After having carried out a correct assembly, the
spring holder (2) must rest against the rockshaft
housing (1), while the spring holder cover (4)
must rest against the flange (3).
In this condition the spring (M) is preloaded by
about 1 mm. Before assembling the complete
reaction assembly to the rockshaft housing a
pre-assembly of the spring (M) is needed in order
to obtain a measurement of about 11.7 mm.
After carrying out the reaction assembly a
definitive adjustment is made. Keep the screw
(V) fixed with an 8 mm wrench and adjust the
self-locking nut (D) by tightening or loosening
it gradually in order to eliminate the axial play
completely.
d) MEASUREMENT CONTROL OF INTERNAL
PUSH ROD
If the rockshaft is disassembled and if the
regulator (R) must be changed it is advisable to
control the measurement (X) (15) in order to
re-assemble the push rod in the same position.
Ensure also that the measurement of the spring
is 55 0/-0.2 mm.
The control of the measurement of the push rod
with respect to the control valve face is carried
out after making all the adjustments (sensitivity
of control valve - position control lever - draft
control lever).
With the rockshaft's arms completely lowered and
without loads or implements on the three point
linkage (neutral position), position the two
control levers (1) and (2) at their lowest position
against the backstop (F).
In this position push the push rod and verify with
the appropriate gauge that the distance of
112 0/+0.5 mm is correct.
NOTE: If the measurement (X) is changed it is
obligatory to carry out again the
adjustment of the position and draft
control levers.
