Servicing the Engine Cooling
System
Remove debris from the engine area, oil cooler and radiator
daily. Clean them more frequently in dirty conditions.
1. Unlatch and swing open rear screen (Fig. 32). Clean the
screen thoroughly of all debris.
Note: To remove screen, lift off hinge pins.

Important Cleaning the radiator or oil cooler with
water will promote premature corrosion damage to
components and compact debris.
4. Pivot the oil cooler back into position. Secure it to the
frame with the latches, close the screen.
Servicing the Alternator Belt
Check the condition and tension of the belts (Fig. 35) after
every 100 operating hours.
1. Proper tension will allow 3/8 in. (10 mm) deflection
when a force of 10 lb. is applied on the belt midway
between the pulleys.
2. If the deflection is not 3/8 in. (10 mm), loosen the
alternator mounting bolts (Fig. 35). Increase or decrease
the alternator belt tension and tighten the bolts. Check
the deflection of the belt again to ensure that the tension
is correct.
