7 MAINTENANCE
7.4 AIR FILTER __________________________________________________________
Clean 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.)
7.5 ENGINE: FAN BELT ___________________________________________________
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 (B) 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 with a
load 10Kgf (98N/22lbs).
3. Re-tighten bolts.
CAUTION
Check the air filter condition indicator situated on the un-
derside of the outlet elbow at regular intervals. If the indi-
cator shows red either clean or replace the air filter
element.
