3-74 INSPECTION AND MAINTENANCE
7) Air cleaner(dry type)
(1) Replacement or cleaning of element
A partially blocked air cleaner will restrict the
flow of air to the engine. Restricted air flow will
decrease the performance of the engine and
increase the fuel consumption and discharging
of black smoke. The air cleaner dust indicator
lamp comes on when the element is restricted.
MTC0130
(2) Cleaning
The element should be cleaned at scheduled
intervals, especially when the air cleaner dust
indicator lamp comes on, and if the engine is
operating in dusty areas or on dirt road, it should
be checked more frequently. Replace when the
element has been clogged severely with dust
particles.
MTS0601
1. Loosen the wing nut to remove the top cover.
Remove the wing nut retaining the element
and take out the element. Handle the
element carefully so as not to cause damage
to it.
2. Blow the dust particle away by directing
compressed air to the inner face of element.
MTC0150
Caution Caution
For the dump truck, avoid loosening the
wing nut fixing the inner element.
Only clean the outer element. Replace both
the outer and inner elements simulta-
neously.
Pressure of compressed air should be 7kg/cm
2
(100
psi) or lower. The stream of compressed air should be
directed from the inside of element to its outside.
Blowing compressed air in a direction opposite to
this will pollute the inside of element. Use only
compressed air, as applying a shock to the outside of
element to remove dust particles will cause damage
to it.
When the rubber valve designed to remove foreign
matters has fallen off, do not block up the valve hole
with a piece of vinyl but RENEW it. Blocking up the
hole with a piece of vinyl can cause damage to the
combustion system or lubricating system.
