Dismantling and Assembly
Loader Valve Controls
The illustration on the adjacent page shows the control rods
and linkages for the loader control valve and is intended as a
guide to the dismantling and assembly.
Dismantling
1
Park the machine on firm level ground, apply the
parking brake. Lower the loader arms and excavator to
the ground, switch OFF the engine and remove the
starter key. Disconnect the battery.
2
Working in the cab, remove the console panels
surrounding the loader levers as shown at
Z
.
3
Uncouple the transmission dump switch electrical
connector and remove the wires from the connector.
Use a screwdriver to release the wires/pins from the
connector, alternatively cut the wires and re-solder on
assembly.
4
Remove the control lever knobs and gaiters.
5
Disconnect the control rods from the loader valve
spools. Remove the bolts securing the complete lever
assembly to the chassis and withdraw the control levers
and mounting bracket through the floor aperture.
Assembly
Assembly is the reverse of the dismantling sequence.
1
Bolt the mounting bracket
A
to the chassis.
2
Fit the rubber cover
B
over the mounting bracket, make
sure it is fitted the correct way round. Do not fix it to the
floor at this stage.
3
Bolt the mounting plate
C
to mounting bracket as
shown.
4
Assemble the loader lever
D
and auxiliary lever
E
together, with the washers and retaining clip as shown.
5
Fit the control rods
F
,
G
and
H
to the lever assembly.
Ensure that the locking flats
X
are at the top.
Note:
If necessary, loosen the lock nuts and rotate the end
fittings to give equal amounts of adjustment (thread) at each
end of the control rod.
6
Fit the lever assembly to the mounting plate
C
as
shown, do not tighten the bolt
J
at this stage.
7
Thread the control rods through the rubber cover
B
and
connect them to the loader valve spools.
8
Adjust the control rods as necessary, see
Adjustment
.
After the control rods are adjusted fit the gaiters over
the control levers.
9
Thread the transmission dump switch cable through the
loader control lever and fit the wires/pins into the
electrical connector. Couple the connector to the
chassis harness and fit the control lever knobs.
10
Connect the battery, check that the controls and
transmission dump switch operate correctly.
11
Refit the rubber cover
B
and the console panels around
the loader levers.
Adjustment
1
Fit the control lever locking pin
K
as shown, tighten bolt
J
when aligned.
Note:
If there is no lever locking pin with the machine use a
suitable diameter metal bar.
2
Adjust the control rods
F
and
G
until the locking pin is a
sliding fit, then tighten the control rods lock nuts.
Note:
Make sure there is an equal amount of thread at each
end of the control rod.
3
Adjust the auxiliary control rod
H
until the auxiliary lever
E
aligns with loader lever
D
, then tighten the control rod
lock nuts.
4
Remove the lever locking pin
K
.
