SECTION 2 - GENERAL SERVICE INFORMATION

Cleanliness

The most important single item in preserving the long ser-
vice life of a machine is to keep dirt and foreign materials
out of the vital components. Precautions have been taken
to safeguard against this. Shields, covers, seals and filters
are provided to keep the wheel bearings, mast sections
and oil supply clean; however, these items must be main-
tained on a scheduled basis in order to function properly.
At any time when hydraulic oil lines are disconnected,
clean adjacent areas as well as the openings and fittings
themselves. As soon as a line or component is discon-
nected, cap or cover all opening to prevent entry of for-
eign matter.
Contaminants in the hydraulic system will affect operation
and will result in serious damage to components working
parts. Every precaution must be taken to keep hydraulic
oil clean, including reserve oil in storage. If the oil must be
poured from the original container into another, be sure to
clean all contaminants from the service container.
Clean and inspect all parts during servicing or mainte-
nance, and assure that all passages and openings are
unobstructed. Cover all parts to keep them clean. Be sure
all parts are clean before they are installed. New parts
should remain in their containers until they are ready to be
used.

Components Removal and Installation

Use adjustable lifting devices, whenever possible, if
mechanical assistance is required. All slings (chains,
cables, etc.) should be parallel to each other and as near
perpendicular as possible to top of part being lifted.
Should it be necessary to remove a component on an
angle, keep in mind that the capacity of an eyebolt or sim-
ilar bracket lessens, as the angle between the supporting
structure and the component becomes less than 90
degrees.
If a part resists removal, check to see whether all nuts,
bolts, cables, brackets, wiring, etc. have been removed
and that no adjacent parts are interfering.

Component Disassembly and Reassembly

When disassembling or reassembling a component, com-
plete the procedural steps in sequence. Do not partially
disassemble or assemble one part, then start on another.
Always recheck your work to ensure that nothing has
been overlooked. Do not make any adjustments, other
than those recommended, without obtaining proper
approval.

Pressure-Fit Parts

When assembling pressure-fit parts, use an "anti-seize" or
molybdenum disulfide base compound to lubricate the
mating surface.

Bearings

When a bearing is removed, cover it to keep out dirt and
abrasives. Clean bearings in nonflammable cleaning sol-
vent and allow to drip dry. Compressed air can be used
but do not spin the bearing.
Discard bearing if the races and balls (or rollers) are pit-
ted, scored or burned.
If bearing is found to be serviceable, apply a light coat of
oil and wrap it in clean (waxed) paper. Do not unwrap
reusable or new bearing until they are ready to be
installed.
Lubricate new or used serviceable bearings before instal-
lation. When pressing a bearing into a retainer or bore,
apply pressure to the outer race. If the bearing is to be
installed on a shaft, apply pressure to the inner race.
Care and Installation of Teflon Coated
Bushings
Bushings:
No jiffy wheels or reaming of any kind can be used on
teflon coated bushings.
Once the coating on the bushing is damaged, it cannot be
used any more and must be replaced.
Pins:
Any rough or damaged surface on a pin will cause the
teflon coating of the bushing to be damaged.
All rust or masking residue must be cleaned from the pin
prior to assembly.
Never dry (black colored) "Arcor" treated pins (hot wash-
ing, vapor...). This will reduce corrosion resistance prop-
erty of pin coating.
Bushings and Pin:
1. Coat inside diameter of bushing with specified lubri-
cant prior to pin installation.
2. Properly align pin and bushing so that the coating
does not get damaged when installing the pin.
3. Pins have chamfered or rounded end to prevent
damage to the coating of the bushing during pin
installation.
