D. Unlatch and raise hood and prop it open. Use
compressed air from the engine fan side to clean the
radiator and oil cooler fins.
E. Assemble components after cleaning is completed.
4. Every 100 hours operation, inspect alternator belt for
condition and proper tension (Fig. 45). Replace belt if
condition warrants. Check and adjust tension as
follows:
A. Unlatch and raise hood and prop it open. Unlatch
and remove right side panel.

B. Unlatch and raise hood and prop it open. Unlatch
and remove right side panel.
C. Proper tension will allow 1/2 in. (13 mm) deflection
when a force of 10 lb. is applied on the belt midway
between the pulleys. If deflection is incorrect,
proceed to step D; if deflection is correct, install
panel and close hood.
D. Loosen the 3 bolts securing alternator to plate and
mounting bracket (Fig. 45). Rotate alternator away
from engine to increase tension and tighten bolts.
Check belt tension after adjustment and re-adjust, if
necessary.
E. Install panel and close hood.
5. Every 100 hours operation, check condition of cooling
system hoses and tightness of connections. Repair, as
needed.
6. Every 1000 hours, or 2 years, drain and flush the
cooling system and replace the thermostat and hose
assemblies.
General Air Cleaner
Maintenance
• Check the air cleaner body for damage which could
cause an air leak. Replace if damaged. Check the whole
intake system for leaks, damage or loose hose clamps.
• Service the air cleaner filter every 200 hours or earlier if
engine performance suffers due to extremely dusty,
dirty conditions. Changing the air filter before it is
necessary only increases the chance of dirt entering the
engine when the filter is removed.
• Be sure the cover is seated correctly and seals with the
air cleaner body.
Servicing the Air Cleaner
1. Release the latches securing the air cleaner cover to the
air cleaner body (Fig. 46).
2. Remove the cover from the air cleaner body (Fig. 46).
Before removing the filter, use low pressure air (40 psi,
clean and dry) to help remove large accumulations of
debris packed between outside of the filter and the
canister. Avoid using high pressure air which could
force dirt through the filter into the intake tract. This
cleaning process prevents debris from migrating into
the intake when the filter is removed.
