SERVICE AND GUIDELINES
0607SE Maintenance Manual 4-5 © Jan 2022
PRESSURE-FIT PARTS
When assembling pressure-fit part, use a molybdenum
disulfide base compound or equivalent to lubricate the
mating surface.
BEARINGS
1. When a bearing is removed, cover it to keep out dirt
and abrasives. Clean bearings in nonflammable
cleaning solvent and allow to drip dry. Compressed
air can be used but do not spin the bearing.
2. Discard bearings if the races and balls (or rollers)
are pitted, scored, or burned.
3. 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 bearings until they are
ready to install.
4. Lubricate new or used serviceable bearings before
installation. 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.
GASKETS
Check that holes in gaskets align with openings in the
mating parts. If it becomes necessary to hand-fabrictae
a gasket, use gasket material or stock of equivalent
material and thickness. Be sure to cut holes in the right
location, as blank gaskets can cause serious system
damage.
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.
1. Always use new replacement hardware when
installing locking fasteners. 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 is
too short, there will not be enough thread area to
engage and hold the part properly. When replacing
parts, use only those having the same
specifications of the original, or one which is
equivalent.
2. 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 recommended shop practices.
(See Fastener Torque Specifications, page 2-8)
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.
HYDRAULIC SYSTEM
1. The primary enemy of a hydraulic system is
contamination. Contaminants enter the system by
various means, e.g., using inadequate hydraulic oil,
allowing moisture, grease, filings, sealing
components, sand, etc., to enter when performing
maintenance.
2. Keep the system clean. If evidence of metal or
rubber particles are found in the hydraulic system,
drain and flush the entire system.
3. Disassemble or reassemble parts on clean work
surface. Clean all metal parts with non-flammable
cleaning solvent. Lubricate components, as
required, to aid assembly.
LUBRICATION
Service applicable components with the amount, type,
and grade of lubricant recommended in this manual, at
the specified intervals. When recommended lubricants
are not available, consult your local supplier for an
equivalent that meets or exceeds the specifications
listed.
BATTERY
Clean battery, using a non-metallic brush and a solution
of baking soda and water. Rinse with clean water. After
cleaning, thoroughly dry battery and coat terminals with
an anti-corrosion compound.
PINS AND COMPOSITE
BEARING
1. Pinned joints should be disassembled and
inspected if the following occurs:
• Excessive sloppiness in joints.
• Noise originating from the joint during operation.
