Reassembly
Assemble the new element into the filter housing ensuring that the seal seats properly. Secure
element by tightening nut.
Before restarting the machine, check that all clamps are tight.
VENTILATION
Always check that the air inlets and outlets are clear of debris etc.
COOLING FAN DRIVE
Periodically check that the fan mounting bolts in the fan hub have not loosened. If, for any
reason, it becomes necessary to remove the fan or re-tighten the fan mounting bolts, apply a
good grade of commercially available thread locking compound to the bolt threads and tighten
to the torque value shown in the TORQUE SETTING TABLE later in this section.
The fan belt(s) should be checked regularly for wear and correct tensioning.
FUEL SYSTEM
The fuel tank should be filled daily or every eight hours. To minimise condensation in the fuel
tank(s), it is advisable to top up after the machine is shut down or at the end of each working
day. Drain any sediment or condensate that may have accumulated in the tank(s). Refer to
MAINTENANCE CHART.
FUEL FILTER WATER SEPARATOR
The fuel filter water separator contains a filter element which should be replaced at regular
intervals (see the SERVICE/MAINTENANCE CHART).
CHARGE AIR COOLER PIPEWORK
Inspect all hoses and clamps on the charge cooler pipe work.
Engine damage will occur if the charge cooling system leaks.
HOSES
All components of the engine cooling air intake system should be checked periodically to keep
the engine at peak efficiency.
At the recommended intervals, (see the MAINTENANCE CHART), inspect all of the intake
lines to the air filter, and all flexible hoses used for air lines, oil lines and fuel lines.
Periodically inspect all pipework for cracks, leaks, etc. and replace immediately if damaged.
