7.1 General
7.1.1 System malfunction
When analyzing a system malfunction, use a
systematic procedure to locate and correct problems
:
- Determine the problem.
- List all possible causes.
- Devise checks.
- Conduct checks in a logical order to determine
the cause.
- Consider the remaining service life of the
components against the cost of parts and
labour necessary to replace them.
- Make necessary repairs.
- Recheck to ensure that nothing has been
overlooked.
7.1.2 Cleanliness
It is important to keep dirt out of working parts to
preserve the long life of the machine. Packing of seals
and filters guarantees the cleanliness of the content.
Whenever hydraulic lines are disconnected, clean the
adjacent area as well as the point of disconnection,
cap the openings to prevent entry of foreign material
in the circuit. The same conditions on cleanliness
apply to mechanical parts.
Clean and inspect all parts. Make sure :
- All passages and holes are open.
- Parts are covered to keep them clean.
- Parts are clean when they are installed.
- New parts are left in their packing until they
are ready for assembly.
- Rust preventive compound has been removed
from all machined surfaces of new parts before
they are installed (except leaf chains).
7.1.3 Removal and installation
When performing maintenance, do not attempt to
manually lift heavy parts when hoisting equipment
should be used. Never place or leave heavy parts in
an unstable position. When raising a portion of a work
platform - or a complete work platform - securely block
the work platform and support the weight of the
machine on blocks (rather than by lifting equipment).
When using hoisting equipement :
- Follow hoist manufacturer's recommendations
- Use lifting devices that will allow you to achieve
the proper balance of the assemblies being lifted
and ensure safe handling.
Unless otherwise specified, all removals requiring
hoisting equipment should be accomplished using an
adjustable lifting attachment. All supporting members
(chains and cables) should be parallel to each other
and as near perpendicular as possible to the top of
the object being lifted.
The capacity of an eybolt diminishes as the
angle between the cable and the vertical
increases. Eyebolts should only have stress
in tension.
Some removals require the use of lifting fixtures to
obtain proper balance.
If a part resists removal, make sure :
- All nuts and bolts have been removed.
- Adjacent parts are not interfering.
7.1.4 Disassembly / Assembly
When assembling or disassembling a component or
system, complete each step in turn :
- Do not partially assemble one part and then
start assembling another part.
- Make all adjustments as recommended.
- Always check the job after it is completed to
ensure that nothing has been overlooked.
- Recheck various adjustments by operating the
machine before returning it to the job.
