Cleaning Air Filter Elements
Do not clean filter elements by bumping or tapping.Do not use filter elements with damaged pleats, gaskets or seals. Engine damage could result.
Filter elements can be cleaned with air pressure, 205 kPa (30 psi) maximum, or water pressure, 280 kPa (40 psi) maximum, or detergent washing. Have spare elements on hand to use while cleaning used elements.* Direct air or water along the length of the pleats inside and outside of filter element. The element can be washed in warm water and nonsudsing household detergent, such as automatic dishwasher detergent. Rinse inside and outside the pleats. The filter should then be thoroughly air dried and inspected. * Inspect the filter elements after cleaning for any rips, tears or damage. Insert a light inside of the clean, dry element. Do not use a filter element with damaged pleats, gaskets or seals. Discard the element if damaged. * Wrap and store the clean filter elements in a clean, dry place.For more information on air cleaner element cleaning, refer to SEBF8062, Guideline for Reusable Parts-Cleaning and Inspection of Air Filters.Belts
Inspect/Adjust
* Inspect the condition and adjustment of the alternator belt and the fan drive belt. Replace the belts if they show any signs of wear.* Adjust the belt tension to minimize belt slippage, to increase belt life, and improve performance of the belt driven components. If belts are too loose, they vibrate enough to cause unnecessary wear on the belts and pulleys. If belts are too tight, unnecessary stresses are placed upon the pulley bearings and belts which might shorten the life of both.* To check the belt tension, apply 110 N (25 lbs) of force midway between the pulleys. Correctly adjusted belts will deflect 13 to 19 mm (1/2 to 3/4 in).Adjust Alternator Belts
Adjusting bolt (1) and mounting bolts (2).1. Slightly loosen mounting bolts (2). Loosen adjusting bolt (1).2. Move the pulley to adjust the belt tension.3. Tighten adjusting bolt (1). Tighten mounting bolts (2). Refer to the Torque Specifications in this manual.Belt Removal and Replacement
If one belt in a set requires replacement, always install a new matched set of belts. Never replace just the worn belt. If only the worn belt is replaced, the new belt will carry all the load, as it will not be stretched as much as the older belts. All the belts will fall in rapid succession.Refer to the Service Manual. If a new belt is installed, check the belt adjustment again after 30 minutes of engine operation at rated speed.Hoses and Clamps
Inspect
* Inspect all hoses for leaks due to cracking, softness and loose clamps. Replace hoses that are cracked or soft and tighten loose clamps.
Do not bend or strike high pressure lines. Do not install bent or damaged lines, tubes or hoses. Repair any loose or damaged fuel and oil lines, tubes and hoses. Leaks can cause fires. Inspect all lines, tubes and hoses carefully. Tighten all connections to the recommended torque.
Check for the following:* End fittings damaged, leaking or
