4. Bolt (Cable Holder)
5. Cable Holder
6. Control Cable

Notice:

Before removing the control cable, be sure to refer to
Items 3 to 6 of “Removal” in the “Removal and Installa-
tion of Control Cable for Rear Dump Truck” in the chap-
ter described previously and perform work in
accordance with the items.

7. Low-Pressure Hose

• Loosen the hose band and remove the hose

from the oil pump.

8. High-Pressure Hose

• Loosen the hose joint and remove the hose

from the oil pump.

Notice:

For the high-pressure hose, a part of the joint may not
be removed according to the type of the truck and equip-
ment. In that case, slightly loosen the joint to set the
state. At the stage where the rear PTO is removed (Item
10), remove the high-pressure hose rotating the PTO
(with oil pump).

Notice:

Because hydraulic operating fluid flows out when the
hose is removed, quickly make the hose port face up-
ward and protect the hose so that dust or foreign matter
will not be mixed in, then fix it to the frame with a wire.

9. Bolt (PTO)

10. PTO (with Oil Pump)

• Remove the six tightening bolts around the

PTO and remove the PTO (with oil pump) from
the transmission.

Notice:

If the high-pressure hose could not be removed in Item
8 described previously, remove the PTO (with oil pump)
from the high-pressure hose rotating the PTO at this
time.
Besides, because this PTO (with oil pump) weighs 15 kg
(147 N), be fully careful of its drop at attachment and de-
tachment.

Installation

Notice:

Before installing the PTO, cleanly remove the liquid gas-
ket left on the PTO installation side of the transmission
case and clean and degrease the transmission case by
waste cloth so that oil will not adhere to it.

1. PTO (with Oil Pump)

• After having cleaned and fully degreased the

transmission installation side of the PTO, coat
it with liquid gasket (LOCTITE 17430 or equiv-
alent).

Notice:

When removing the PTO side from the high-pressure
hose rotating the PTO side at PTO (with oil pump) re-
moval, install the PTO (with oil pump) in the high-pres-
sure hose and lightly tighten it.

2. Bolt (PTO)

• Install the PTO (with oil pump) in the transmis-

sion and tighten the bolt at a specified torque.

Tighten:

PTO bolt to 45 N

3. High-Pressure Hose

• Install the high-pressure hose in the oil pump

and firmly tighten the joint.

Notice:

When the PTO (with oil pump) is installed in the high-
pressure hose rotating the PTO in Item 10 described
previously, firmly tighten the joint.

4. Low-Pressure Hose

• Install the hose and firmly tighten the hose

band.

Notice:

When installing the high-pressure hose and the low-
pressure hose, be fully careful so that dust or foreign
matter will not be mixed in the pose port and the oil
pump.

5. Control Cable
6. Cable Holder
7. Bolt (Cable Holder)

Notice:

Install the control cable and cable holder in the PTO in
accordance with Items 1 to 4 of “Installation” in the “Re-
moval and Installation of Control Cable for Rear Dump
Truck”, and after installation inspect and adjust it in ac-
cordance with the “Amount of Spool Extrusion”.
