6. PUMP DISASSEMBLY
6.1 General Comments
Maintenance and repair that is outside the
scope of the operators handbook must be
done in a suitable location equipped with
lifting equipment with a capacity of at least
1500 kg.
A clean and sound floor with work stands or
benches will provide for ease of access and
a safe working environment.
To avoid the possibility of maintenance
personnel inhaling dangerous fumes or
vapours.
It is recommended that
maintenance work be carried out away from
the pump location by removal of the pump
unit to a suitable maintenance area.
Disconnect the negative battery lead before
maintenance work is done. Electrical
checks and repair may require the battery
to be connected, refer to section 10 for
testing instructions.
On trailer units ensure that the rear prop
stand is lowered and the jockey wheel is
wound down to apply load to the rear prop
stand before removing any heavy pump
components. If the pump is removed from
the engine without removal of the engine,
support the chassis with wooden blocks or
adjustable stands to prevent toppling.
6.2 Battery Removal Procedure
1. Disconnect the negative battery lead then
the positive battery lead from the battery.
2. Remove the retaining nuts (4) and strap (1)
and lift out the battery.
3. If required, remove the retaining bolts (2)
and lift the battery tray assembly out from
the chassis.

hazardous liquid from the pump casing and
priming tank.
2. Disconnect the flexible drain hoses from the
stop valve on the pump casing and from the
stop valve on the coalescer.
3. If the engine is to be overhauled, drain the
sump at this stage and disconnect the
engine sump drain hose from the stop valve
on the engine.
4. Disconnect the wiring loom from the engine.
Refer to the wiring diagrams in section8.
5. Disconnect the probe, solenoid and clutch
cables (where fitted) from the priming
