D. Internal push rod setting
With reference to figure 4.
If the rockshaft is disassembled and if the regulator (R)
must be changed it is advisable to control the measure-
ment "X" (~10,5) in order to re-assemble the push rod
in the same position.
Ensure also that the measurement of the spring is 46.00
- 46.30 mm (1.81 - 1.82 in).
The control of the measurement of the push rod with re-
spect 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 rock shaft's arms completely lowered and with-
out loads or implements on the three point linkage (neu-
tral position), position the two control levers (1) and (2)
at their lower position against the backstop (F).
In this position push the push rod and verify with
the appropriate gauge that the distance of 112.00 -
112.50 mm (4.41 - 4.43 in) 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.
