(18)Fuel Injection Nozzles
Whenever an engine performs in such a manner that a fuel injection valve is suspected of causing trouble, test all fuel injection valves by loosening the fuel injection line nut at the pump.When a nut is loosened and the exhaust smoking is completely or partially eliminated and the irregularity in running is not affected, this identifies the probable location of a defective fuel injector.Your authorized dealer has the proper tools for cleaning and testing fuel injection valves.To Remove Injector:
1. Clean dirt from around fuel injector. 2. Remove the fuel injection line at the valve housing.Immediately install plugs in the fuel line nuts to prevent dirt from entering the fuel injection line.3. Remove the valve retainer nut, and nozzle assembly.To Install:
1. Screw the valve body into the nozzle assembly.2. Insert the nozzle assembly and valve body.3. Install the retainer nut and tighten to 105 lb.ft. (142 N m).
Do not overtighten. Use a torque wrench. Overtightening or undertightening can cause fuel nozzle and engine failures.
4. Connect the fuel injection line and tighten.(19)Air Compressor
1. Inspect the performance of the air compressor.2. Rebuild or replace the air compressor if needed.3. Thoroughly inspect all connections for tightness before placing the vehicle in use.(20)Cooling System - Cleaning
At operating temperature, the engine coolant is hot and under pressure.Steam can cause personal injury.Check the coolant level ONLY when the engine is stopped and the filler cap is cool enough to touch with your hand.Remove the filler cap slowly to relieve pressure.Cooling system conditioner contains alkali. Avoid contact with skin and eyes to prevent personal injury.
All water is corrosive at engine operating temperature. Use Caterpillar Cooling System Conditioner liquid, or equivalent.
Never add coolant to an overheated engine; allow the engine to cool first.Do not use Caterpillar Cooling System Conditioner with Dowtherm 209 coolant.
If the truck is to be used or stored in an area with below freezing temperatures, the cooling system must be protected to the lowest expected ambient temperature.
1. Loosen the radiator cap slowly to release the pressure. Remove the radiator cap. 2. Remove the cooling system drain plug, and allow the coolant to drain.
Use all cleaning solutions with care.
Most commercial cooling system cleaners may be used. The best cleaner is chelate-type alkaline cleaners.3. Install the drain plug. Fill the system with cleaning solution. 14. Start and run engine for 1/2 hour. Stop the engine and drain cleaning solution.5. Flush the system with clean water until the draining water is clean. Do not run the engine while flushing.6. Install the drain plugs. Fill the system with neutralizing solution. 27. Start and run the engine for 10 minutes. Stop the engine and drain neutralizing solution.8. Flush the system with clean water, until the draining water is clean. Do not run the engine while flushing.9. Install the drain plug.10. Add the correct amount of Caterpillar Cooling System Conditioner, or equivalent, so that the cooling system will have a 3% concentration. Add 1 pint (.5 liter) for each 4 gal. (15 liter) of coolant.11. To help avoid
