Bushing Installation:
1. Use an appropriate driver (soft steel) to insert bush-
ing in its housing.
2. Slightly oil the outside diameter of the bushing to
facilitate insertion.
3. Keep driver, bushing and housing correctly aligned
during assembly.
4. Blocking must be used on parts that will receive two
flange bushings to prevent damage to the lower
bushing flange.

Bolt Usage and Torque Application

NOTICE
SELF LOCKING FASTENERS, SUCH AS NYLON INSERT AND
THREAD DEFORMING LOCKNUTS, ARE NOT INTENDED TO BE
REINSTALLED AFTER REMOVAL.
31210090
SECTION 2 - GENERAL SERVICE INFORMATION
Use bolts of proper length. A bolt which is too long will
bottom before the head is tight against its related part. If a
bolt if too short, there will not be enough thread area to
engage and hold the part properly. When replacing bolts,
use only those having the same specifications of the origi-
nal, or one which is equivalent.
Unless specific torque requirements are given within the
text, standard torque values should be used on heat
treated bolts, studs and steel nuts, in accordance with rec-
ommended shop practices or the Torque Chart in Section
1 of this Service Manual.

Hydraulic Lines and Electrical Wiring

Clearly mark or tag hydraulic lines and electrical wiring, as
well as their receptacles, when disconnecting or removing
them from the unit. This will assure that they are correctly
reinstalled.
Coat contacts of electrical connectors with silicone dielec-
tric compound (Refer to Section 11).
Always disconnect battery plug (located in the battery
compartment) prior to working on the electrical system.

Hydraulic System

EXERCISE EXTREME CARE AROUND PRESSURIZED HYDRAULIC
SYSTEMS WHILE IN OPERATION OR UNTIL ALL PRESSURE IS
RELEASED.
HIGH PRESSURE OIL COULD PENETRATE SKIN AND CAUSE
INJURIES OR BURNS. LOOSEN FITTINGS OR COMPONENTS
SLOWLY TO ALLOW OIL PRESSURE TO DROP GRADUALLY.
When servicing the hydraulic system, use a container to
collect the oil from hydraulic lines or components and pre-
vent it from spilling on the work platform or on the ground.
NOTE: Used oils and filter cartridges must be disposed of
according to regulation in force.
Before disconnecting a hydraulic line or removing a com-
ponent, clean fittings and adjacent area. As soon as a line
or component is disconnected, cap or cover all opening
to prevent entry of foreign matter.
Disassemble and reassemble hydraulic parts on clean
work surface. Clean all metal parts with non-flammable
cleaning solvent. Lubricate components, as required, to
aid assembly.
Keep the system clean. Hydraulic system filter should be
replaced at the specified intervals. Examine filter cartridge
for evidence of metal or rubber particles. If evidence of
metal or rubber particles is found, drain and flush the
entire system.
