General Information and Specifications
2.34 Model 8042, 10042, 10054 Legacy Rev. 10/03
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.
2.11 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
rating 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 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 your hand in
contact with the tank, the oil should be within the proper
range.
2.12 AFTER SERVICE STARTUP AND
CHECKS
2.12.1 After Service Startup
Note: Refer to the Owners/Operators manual for engine
cold start procedures.
1. Check ALL fluid levels, and add fluid as required.
2. Connect the negative (-) battery cable or cables to
the negative (-) battery terminal or terminals if the
cable or cables were 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 and smooth 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 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 or cables to
the negative (-) battery terminal or terminals if the
cable or cables were disconnected.
7. Start the engine and purge the hydraulic system of
air.
8. Check the operation of the replaced electrical
component(s).
