Diesel Exhaust Fluid Filter - Replace

Ensure that the engine is stopped before any servicing or repair is performed.

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product.

Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.

Dispose of all fluids according to local regulations and mandates.

The DEF filter is located on the left side of the machine under the cab. Tilt the cab upward. Refer to the Maintenance Section, “Cab Tilting” for the procedure.

Remove the black plastic cover and then diesel exhaust fluid (DEF) filter assembly, which is shown.

Install new DEF filter. Replace DEF filter cap.

Tilt the cab downward. Refer to Maintenance Section, “Cab Tilting” for the procedure.

If a new belt is installed, check the belt adjustment after 30 minutes of operation. A belt is considered used after 30 minutes of operation.

1. Stop the engine in order to inspect the belt.

2. Open the engine access door. Refer to Operation and Maintenance Manual, “Access Doors and Covers”.

3. Loosen the quarter-turn fasteners (1) on the front of the guard.

4. Remove the guard for the V-belt.

5. Inspect the condition of the belt and the adjustment of the belt. The belt should deflect 10 mm (0.39 inch) to 12 mm (0.47 inch) under a straight pull of 10 kg (22 lb). This measurement should be taken between the alternator pulley and the crankshaft pulley.

Note: A 144-0235 Borroughs Belt Tension Gauge may be used to measure belt tension. This measurement should be taken between the alternator pulley and the crankshaft pulley. Refer to the following table for belt tension.

6. Loosen the mounting bolt (4). Loosen the adjusting bolt (5).

Cooling System Coolant Extender (ELC) - Add

When a Cat Extended Life Coolant is used, an extender must be added to the cooling system periodically.

Open the engine access door and raise the radiator guard. Refer to Operation and Maintenance Manual, “Access Doors and Covers”.

Note: The radiator cap may be located either on the left side of the radiator (C3.3B and C3.8 engines) or the right side of the radiator (C2.2 engine).

Slowly loosen the radiator cap in order to relieve system pressure. Remove the radiator cap.

If necessary, drain enough coolant from the radiator in order to allow the addition of the coolant additive.

Add 0.17 L (0.18 qt) of cooling system additive.

Inspect the radiator cap and the gasket. If the cap or the gasket is damaged, replace the cap. Install the radiator cap.

Check the coolant level in the sight gauge on the radiator. Maintain the coolant level to the top of the sight gauge with the radiator in the LOWERED position.

Rotate the latch to free the cover from the ductwork. Did it come off without using excessive force?

Cooling System Coolant Sample (Level 1) - Obtain

Warning: Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.

Start the engine and allow the engine to run for at least 15 seconds to recharge the accumulator.

Stop the engine. Keep the armrests in the LOWERED position. Turn the engine start switch to the ON position. Push the parking brake switch.

Move the electrohydraulic controls through all the positions.

Toggle the auxiliary switch multiple times.

Turn the engine start switch to the OFF position. The pressure in the hydraulic system has now been released.

Note: Some hydraulic lines on the downstream side of the accumulator may still contain pressurized oil. Use caution when you disconnect these hydraulic lines.
