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 air locks, add coolant slowly, at 5 U.S. gallons (20 liters) per minute or less.12. Add antifreeze solution. See REFILL CAPACITIES.13. Start and run the engine with the radiator cap removed. Allow coolant to warm and level to stabilize.14. Add coolant, if necessary, to bring the coolant level to the bottom of the fill pipe.15. Observe condition of the radiator cap gasket. Replace if it is damaged.(1)2 lb. Sodium Bisulfate (NaHSO4) per 10 U.S. gallons (1 kilogram per 10 liters) water.(2)1/2 lb. Sodium Carbonate Crystals (Na2CO3 10H2O) per 10 U.S. gallons (250 grams per 40 liters) water.(21)Batteries
1. Loosen and remove cable clamps from all battery terminals.2. Clean all cable clamps.3. Clean all battery terminals.4. Install the cable clamps on the battery terminals. Make sure they are secure.5. Apply a light coat of grease on the battery connections.(22)Starting Aids - Checking Glow Plugs
1. Disconnect the wire lead from the glow plug terminal on the HEAT-START switch.2. Install an ammeter with a capacity of over 75 amps, in a series, between the disconnected lead and the terminal on the HEAT-START switch.3. Turn HEAT-START switch to HEAT.4. Observe the ammeter. Each 12 volt glow plug draws approximately 12.5 amperes and each 24 volt glow plug draws approximately 6.5 amperes. The ampere draw of one glow plug multiplied by 6 will be the total ampere draw of the glow plugs in the engine. A low reading indicates one or more defective glow plugs.5. If a defective glow plug is indicated, disconnect one glow plug lead at a time.6. Turn switch to the HEAT position. Observe the ammeter. Reconnect the lead.7. The glow plug that does not change the reading on the ammeter, when the switch is turned on, is the defective glow plug.(23)Engine Mounting Bolts
Tighten the engine mounting bolts. See BOLT TORQUE CHART.(24)Crankshaft Seals
1. Inspect for front seal leakage. 2. Inspect for rear seal leakage.(25)Turbocharger
1. Remove the turbocharger air inlet and the exhaust outlet.2. Rotate the compressor and turbine wheel by hand.3. The assembly should rotate freely. Feel for e
