Bowl - Apron and Ejector
INSTALLATION
Ejector
Numbers in parentheses refer to Fig. 1.
Note: Tighten all fasteners to standard torques listed
in Section 300-0080, STANDARD BOLT AND NUT
TORQUE SPECIFICATIONS.
1.Using suitable lifting equipment attached to lifting bar
(11), position ejector assembly (10) on vehicle. When
properly aligned, drive ejector hinge rods (14) through
hinge tubes (12).
2. Weld the cover plates over ejector hinge openings.
Refer to 'Welding' section for proper procedure.
3. Place the battery master switch in the 'On' position,
start the engine and check the operation of the apron
and bowl linkage.
4. Ensure parking brake is applied and remove wheel
blocks from all road wheels.
MAINTENANCE
Inspection
Inspect the apron and ejector assemblies periodically
for cracked or broken welds and bending/twisting. Any
defects found should be repaired before they progress
into major failures. Moving parts, such as levers, apron
arms and ejector hinges should be checked for wear
and for binding. Worn parts should be replaced before
they break and cause considerable damage to the
vehicle.
Straightening
Hydraulic straightening or aligning equipment should
be used to straighten bent or twisted components
whenever possible. However, if heat must be applied,
never heat the metal beyond a dull cherry red colour,
as too much heat will weaken the metal. When it is
necessary to heat the metal, apply heat uniformly over
the area to be straightened and protect the heated
surface from sudden cooling. Any parts buckled
sufficiently to show cracks or signs of strain afer cold
straightening should be reinforced or replaced.
Welding
WARNINGS
Before any welding is done on a machine
equipped with the HEUI electronic
management system, disconnect the following
in this order: Battery earth cable, battery
supply cable, alternator earth cables, alternator
supply cables, front & rear transmission ECU
connectors (located behind access door below
cab door) and front & rear engine ECU
connectors (located on LH side of engine).
Turn off battery master switch before
disconnecting any components. After welding
connect all of the above in the reverse order.
Welding and flame cutting cadmium plated
metals produce odourless fumes which are
toxic. Recommended industrial hygiene
practice for protection of the welding operator
from the cadmium fumes and metallic oxides
requires enclosure ventilation specifically
designed for the welding process. A
respiratory protective device such as the
M.S.A. 'Gasfoe' respirator with G.M.A. cartridge
will provide protection against cadmium,
fumes and metallic oxides. The 'Gasfoe'
respirator has been approved by the U.S.
Bureau of Mines: Approval number 23B-10,
and is designed to protect against gases,
vapours, and/or metal fumes.
Note: Prior to welding, switch off/disconnect the
following in the order given. Failure to do so may
seriously damage the machines electrical
components.
a - Turn keyswitch off
b - Turn battery master switch off
c - Battery earth cables
d - Battery supply cables
e - Alternator earth cables
f -
Alternator supply cables
g - Transmission ECU connectors (front & rear)
h - Engine ECU connectors (front & rear)
After welding, connect all of the above in the reverse
order.
