• At this time, check that the “L” dimension is
34
±1 mm (1.339±0.039 inch.)
• If the “L” dimension does not satisfy the speci-
fied value, remove the cable holder from the
PTO and rotate the cable holder to adjust the
dimension.
Notice:
Both “clockwise rotation” and “counterclockwise rota-
tion” indicate that the cable moves by about 0.75 mm
(0.0295 inch) every time the cable holder rotates by 180
degrees.
• Re-install the cable holder on the PTO and tem-
porarily tighten the bolt.
4. Lock Nut (PTO Side)
• After having checked the specified value di-
mensions of the cable outer threaded portion,
temporarily tighten the lock nut.
Notice:
Tighten the special nut and lock nut after having adjust-
ed it in accordance with the work procedure of the “Con-
trol Cable Adjustment”.
5. Clip (Cab Inside)
• Draw the control cable in the instrument panel
bottom inside the cab and firmly install the
grommet.
• Firmly install and fix the clip in the cable flange
portion groove.
6. Lock Nut (Dump Lever Side)
• Assemble the control cable tip in the boss por-
tion of the dump lever and tighten the lock nut
at a specified torque.
Tighten:
Lock nut to 6 N

Notice:
If the double nut position of the control cable is not fixed,
it is fixed to a reference value.

Control Cable Adjustment
Inspecting the Amount of Spool Extrusion
After having installed the control cable, inspect the
amount of spool extrusion according to the following
procedure.
1. Remove the shift cap tightening bolt of the oil pump
rear and remove the shift cap.
2. Repeat the “Up” and “Down” operations of the
dump lever twice or three times and slowly set the
dump lever to the “Up” position as much as possi-
ble.
3. Measure the amount of spool extrusion of the oil
pump rear and check that it is a specified amount.
Amount of spool extrusion: 24 mm (0.945 in) or more
4. Repeat the “Up” and “Down” operations of the
dump lever twice or three times and slowly set the
dump lever to the “Up” position as much as possi-
ble.
5. Measure the amount of spool extrusion of the oil
pump rear and check that it is a specified amount.
Amount of spool extrusion: less than 2 mm (0.0787 in)
Notice:
Both amounts of spool extrusion at “Up” and “Down”
shall be within a standard value.

6. If the amount of spool extrusion is within a speci-
fied dimension, install the shift cap and tighten the
bolt at a specified torque.
Tighten:
Shift cap fixing bolt to 24 N
⋅m (2.4 kg⋅m / 17 lb⋅ft)
Notice:
If the groove is not installed facing downward, the water
intruded in the shift cap is not ejected but collected.
Rusting and freezing will cause an incorrect actuation.
Cable Adjustment (PTO Side)
If no specified extrusion dimensions can be obtained as
a result of measuring the amount of spool extrusion de-
scribed previously, adjust (PTO side) the cable so that
the specified amount of spool extrusion can be obtained
according to the following procedure.
1. Loosen the lock nut of the control cable.
2. Remove the tightening bolt of the cable holder.
3. Adjust the cable rotating the cable holder.
• If the amount of spool extrusion is improper (in-
sufficient) at “Dump lever Up”, rotate the cable
holder toward “Counterclockwise rotation”
shown by the arrow mark of the drawing.
• If the amount of spool extrusion is improper (ex-
cessive) at “Dump lever Down”, rotate the cable
holder toward “Clockwise rotation” shown by
the arrow mark of the drawing.
Notice:
Both “clockwise rotation” and “counterclockwise rota-
tion” indicate that the cable moves by about 0.75 mm
(0.0295 inch) every time the cable holder rotates by 180
degrees.
