9 LUBRICATION & MAINTENANCE
9.16 AIR CLEANER - DIESEL
IMPORTANT
WE RECOMMEND THAT THE FILTER ELEMENT
BE REPLACED BEFORE ENGINE
PERFORMANCE IS AFFECTED. THIS MAY
OCCUR AT 250 HOURS OF SERVICE UNDER
VERY DUSTY CONDITIONS OR AT 500 HOURS
UNDER NORMAL OPERATING CONDITIONS.
WE DO NOT RECOMMEND CLEANING THE
FILTER ELEMENT BECAUSE OF THE
POSSIBILITY OF DAMAGING IT.
CHECKING THE ELEMENT
To check for damage, pin holes, etc. shine a light
source into the end of the element. If light CANNOT
be seen through the paper, a new element should
be installed. Likewise, if pinholes of bright light
appear in the paper, the element should be
replaced.
INSTALLING ELEMENT
1. Clean the dust from inside the filter housing
with a damp cloth. Make sure that dust does
not enter the engine air intake.
2. Check the soft gasket material at both ends of
the element to be sure it is not damaged.
9.17 FAN BELT TENSION - DIESEL
The tension on the belt is correct when the belt can
be depressed 7 to 9mm (0.28 - 0.35in) under a load
of 10kgf (22lbs) midway between the crankshaft
pulley and the alternator pulley.
To adjust:
(a) Release the two bolts (A ) holding the
alternator and adjust alternator until the

3. Insert the open end of the element into the
housing and press it onto the air intake pipe
at the back of the housing. Make sure the
filter element fits over the pipe snugly and is
pushed all the way on to prevent any dust
from getting past the filter.
4. Install the air cleaner cover 1 over the
element with the dust collector 2 pointing
DOWN (dust collector empties automatically
when properly installed). Secure the cover
with the two wire clips 3.
