General Information and Specifications

2.10.3

Bearing Installation

1. Always install bearings carefully to help avoid

damaging their delicate surfaces.

2. Install bearings using one of the following methods:

• PRESS FIT for installation on rotating parts such

as shafts and gears

• PUSH FIT into static locations such as reduction

gear housings

3. Always install the bearing into the rotating part first,

whenever possible.

4. Use a press or the proper installation tools when

installing a bearing or bushing.

5. In the absence of a press or proper installation tools,

carefully heat the casing and/or bearing in hot oil to
assist in the installation.

PRESSURE TESTING AND
ADJUSTMENT

Prior to pressure testing or adjustment, verify that all
hoses and tubes are in good condition and that all fittings
are tight.

Use pressure gauges with the proper pressure range and
ratings to measure the specified pressures.

Use correct test procedures to help prevent personal
injury, and damage to the system or test equipment.

Verify that the hydraulic oil is at the proper operating
temperature, 80-120° F (27-49° C), before testing any
pressures or making any adjustments to any valves. If
necessary, operate the vehicle to raise the oil
temperature up to the operating temperature. In the
absence of a temperature gauge, the oil temperature can
be checked by placing your hand against the side or the
bottom of the hydraulic oil reservoir. If the tank is too hot
to keep the hand in contact with the tank, the oil
temperature should be within the proper range.

AFTER SERVICE STARTUP AND
CHECKS

2.12.1

After Service Startup

Note: Refer to the appropriate Owners/Operators man-
ual for engine cold start procedures.

1. Check ALL fluid levels, and add fluids as required.

2. Connect the negative (-) battery cable to the

negative (-) battery terminal if it was disconnected.

3. Start and idle the engine. Check for leaks from the

hydraulic components, engine, radiator, axles,
transmission and brakes. Check for leaks from the
hydraulic oil reservoir plugs or fittings; tighten as
required. Check the levels of all fluids and lubricants.

4. Purge the hydraulic system of air by operating all

vehicle functions through their entire range of
motion. Operate all functions several times to ensure
all air is purged from the system.

5. Check for proper operation of all components.

6. Retract all cylinders fully. Turn the engine OFF, and

check the hydraulic oil level in the hydraulic oil
reservoir. Allow the oil to cool and recheck the level.
Add oil as required to bring the oil level up to the
proper level.

2.12.2

After Electrical/Electronic Component
Service

1. Check the torque of all fasteners securing replaced

electrical/electronic components.

2. Check wire connections to electrical components.

3. Verify that wiring components are dry and free of

moisture.

4. Check connectors for broken, frayed or loose wires.

5. Check wires and wire harnesses for brittle or frayed

wire shielding.

6. Connect the negative (-) battery cable to the

negative (-) battery terminal if it was disconnected.

7. Check the operation of the replaced component(s).
