ADJUSTMENTS
a.
Adjusting the Position Control
Connect the lower links to a dead weight
of 450kg.
Open the isolating valve and set the draft
lever to the deepest position. Lift the
weight by operating position control lever
slowly until the distance from the center
line of the top hitch pin to the center line
of the lift arm pin is 620mm lock the
position control lever stop firmly behind
the lever in touching position.
NOTE : Check that this is correctly set by
lowering and lifting to the top again with
the position control lever. It should now
be possible to lift the links a further
12.5mm approximately by moving the draft
control lever to the top most position.
b. Checking the relief valve pressure. Fit
pressure gauge (0-214 kg/cm
2
) in the
external jack tapping. Close isolating valve.
Put engine to full throttle and lift the draft
control lever in the top most position the
pressure reading should be as per
specification (123-157 kg/cm
2
)
To avoid overheating the
system the pressure test should not be
maintained for more than 30 seconds.
After completion of the test the draft
control lever must be returned to the
deepest position otherwise serious
damage to the hydraulic system may result.
If the recorded pressure is not 154-168 kg/
cm
2
. It can be increased or decreased by
adding or removing shims in the relief valve
sping housing. Addition of one 0.076 mm
will increase by 3.5 Kg/cm
2
and removal of
one shim will decrease the pressure by 3.5
Kg/cm
2
.
