Adjust Alternator Belts
3. Loosen the mounting pivot bolt (1). Loosen the adjustment nut(s) (2).4. Adjust the alternator in or out by either tightening or loosening adjustment nut(s) as required to obtain the correct adjustment.5. Tighten bolts (1) and (2). Check the belt tension. Install the belt guard.If new belts are installed, check belt adjustment again after 30 minutes of engine operation. Repeat belt tightening if required.Adjust Fan Drive Belts
1. Loosen bolts holding the fan mounting plate to the engine.2. Loosen locknut and turn adjusting screw until the belts are properly adjusted.3. Tighten bolts and locknut.4. Check the belt adjustment. If adjustment is not correct, repeat steps 1 through 3.Inspect/Replace Hoses and Clamps
Hose replacement prior to failure is a good preventive maintenance practice. Replacing a hose before it fails reduces the chances for unscheduled downtime. By replacing a hose that is cracked, soft or leaking, major repairs will be avoided that could result in a severe engine overheating problem.* Inspect all hoses for leaks due to cracking, softness and loose clamps.* Replace hoses that are cracked or soft and tighten loose clamps.Before Replacing Hoses
1. Loosen the cooling system filler cap slowly to relieve any pressure and remove the cap.2. Drain the coolant from the cooling system to a level below the hose being replaced. Remove the hose clamps, disconnect the old hose and replace with a new hose. Install hose clamps. See the Torque for Standard Hose Clamps chart in the Torque Specifications section of this publication for the appropriate torque.After Replacing Hoses
Refer to the Cooling System Specifications section in this publication for information about cooling system requirements.3. Add proper coolant mixture to the cooling system. Fill system to the proper level. Install the filler cap. Start the engine and inspect for cooling system leaks.4. Check coolant temperature reading frequently for proper operating temperature.Engine Air Cleaner
Never service the air cleaner with the engine running since this will allow dirt to enter the engine. Check the inlet piping for leaks. Make all repairs to inlet piping immediately, as dirt and debris could enter the engine causing damage to the turbocharger and engine components.Clean or replace elements using these recommendations and/or your weather and operating conditions, or when required by the restriction indicator.
Replace
Regular service intervals, along with close visual inspection of the air cleaners are necessary for proper cleaning of the engine inlet air. The interval will vary with the weather and operating conditions. It will be necessary to service the air cleaners more frequently in salty, dry weather conditions or where airborne dust and debris is present. In damp weather conditions the service interval may be extended, however the elements should be replaced EVERY YEAR.Visual inspection of the gaskets and seals is important to keep dust from bypassing the cleaner elements. If the gaskets and seals or the element pleats are damaged, replace them. Extra filter elements should be kept on hand for replacement or for use while elements are being cleaned.
