5.1. System malfunctions
When analysing a system malfunction, use a systematic
procedure to locate and correct problems :
- Determine problem.
- List possible causes.
- Plan checks.
- Conduct checks in a logical order to determine
the cause.
- Consider remaining service life of components
against cost of parts and labour necessary to
replace them.
- Make necessary repairs.
- Recheck to ensure that nothing has been
overlooked.
- Functionally test failed part in its system.
NOTE
Your safety and that of others is always the
number one consideration when working
around machines. Safety is a matter of
thoroughly understanding the job to be done
and the application of good common sense.
It is not just a matter of do's and don'ts. Stay
clear of all moving parts.
5.2. Cleanliness
Keep dirt out of working parts to preserve the long life
of the machine. Enclosed compartments, seals and
filters keep the supply of air, hydraulic oil and
lubricants clean. Maintain these enclosures properly.
Whenever hydraulic lines are disconnected, clean the
adjacent area as well as the point of disconnection.
As soon as the disconnection is made, cap, plug or
tape each line or opening to prevent entry of foreign
material. The same recommendations for cleaning and
covering apply when access covers or inspection pla-
tes are removed.
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 containers until ready
for assembly.
- Rust preventive compound has been removed
from all machined surfaces of new parts before
they are installed (except leaf chains).
5.3. Removal and installation
When performing maintenance, do not attempt to
manually lift heavy parts when hoisting equipment
should be used. Never locate 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 ma-
chine 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 eyebolt diminishes as the
angle between the supporting members and
the object becomes less than 90°. Eyebolts
and brackets should never be bent and 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.
5.4. Disassembly and 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.
