8.10 AIR FILTER - DIESEL__________________________________________________
Clean Air Filter Element
Note: Check the air filter condition indicator situated on the
underside of the outlet elbow at regular intervals. If the
indicator shows red either clean or replace the air filter
element.
1. As the element of the air cleaner employed on this
engine is a dry type, never apply oil to it.
2. Open the evacuator valve once a week under
ordinary conditions-or daily when used in dusty
conditions to get rid of large particles of dust and dirt.
3. Avoid touching the element except when cleaning.
4. When dry dust adheres to the element, blow
compressed air from the inside turning the element.
Pressure of compressed air must be under 7kgf/cm2
(100psi). Wear the appropriate personal protective
equipment
5. When carbon or oil adheres to the element, soak the element in detergent for 15 minutes then wash it
several times in water, rinse with clean water and dry it naturally. After the element is fully dried, inspect
inside of the element with a light and check if it is damaged or not. (referring to the instructions on the label
attached to the element.)
8.11 ENGINE: FAN BELT - DIESEL___________________________________________
Check & Adjust Fan Belt.
The fan belt is adjusted so that it has sufficient tension to
avoid undue stress on alternator bearings but does not slip
on the alternator pulley. Use the following procedure to
check the belt tension at the mid-point of the belt between
crank shaft and alternator pulleys.
1. Loosen alternator bolt (A) and pivot bolt on the
underside of the Alternator.
2. Move the alternator to tighten or loosen the belt so
that a deflection of 7 to 9 mm is achieved at the mid-
span (B) with a load 10Kgf (98N/22lbs) for a new belt, and 8 to 10mm for a used belt.
3. Re-tighten bolts.
A. Cover, B. Evacuator valve
