Engine
Engine Drive Belt
The engine drive belt is a serpentine belt that has
a self tensioner on it. The belt requires inspection
at regular service intervals. If the belt begins to slip
the belt may require replacement as it can become
laminated or slippery. If the tensioner loses its
tension it can also cause the belt to slip and must be
replaced. The belt should be replaced every 1000
hours.
To replace the engine drive belt insert a ½" drive
into the tensioner arm and pull upwards.
Pull the belt off the pulleys and off the fan.
Fit the new belt in reverse, ensure all pulleys are
aligned correctly with the belt before releasing the
tensioner.
Engine Fan Hydraulic Pump Belt
The engine fan hydraulic pump belt have a manual
adjuster. To tension the belt, the pump mounting bolt
and tensioner must to be loosened. Use the lock
nuts located on the tensioner to pivot the pump
and tension the belt. When the belt is tensioned
correctly tensioned to approximately 19 mm
deflection, tighten the lock nuts on the tensioner and
the pump mounting bolt.
If the belt is over tight, damage may be done to the
pump shaft and pulleys.
Air Conditioner Belt
The air conditioner compressor belt has a manual
adjuster. To tension the belt the compressor
mounting bolt and adjuster bolt must be loosened.
To tighten the belt, use the lock nuts on the adjuster
to pivot the compressor and pull the belt tight.
When the belt is correctly tensioned tighten the
retaining hardware.
There should be no more than 12 mm deflection
in the belt when it is tensioned correctly. The
compressor belt should be replaced every 1000
hours.
Engine Air Cleaner
The air cleaner is mounted to the top of the engine
on the front right hand side. Mounted on the right
hand side of the hydraulic oil tank frame is a vacuum
gauge (this can be seen from the cabin). This is used
to detect a blocked air filter. The gauge will operate
in the middle range when in normal working
G4.7, G5, G6 Crop Cruiser Operator's Manual MY19 - REV 0
conditions, and in the 'RED' zone when blocked. This
indicates it is time to remove the primary filter and
replace it.
It is recommended to inspect the filters when the
machine is new. Inspection of the primary filter
should be carried out at service intervals or when
the vacuum gauge indicates. NEVER clean the
secondary filter, this filter should be replaced if it is
contaminated or damaged.
Cabin Air Cleaner
A carbon air cleaner is fitted to the right hand side
of the cabin. This filter cleans the impurities from the
air being drawn into the cabin. The air is drawn in
through the carbon filter by a fan and pressurises the
cabin to prevent impure air entering the cab from
any holes or seal leaks. The filter elements have a
foam pre-cleaner covering them, this foam element
can be removed and washed in water. The element
must be totally dried before refitting. Carbon balls
inside the filter capture any impurities in the air that
are drawn through it. A colour indicator on the end
of the filter identifies when the carbon balls need
to be recharged to maintain filtering effectiveness.
By removing the element from the housing and
inspecting the colour of the carbon balls the service
life can be witnessed. When the indicator shows the
filter needs to be recharged it must be replaced with
a new carbon filter or recharged by a certified agent.
COLOUR GUIDE:
