CAT CAT Skid Steer Loader 226D 226D

Warning: Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.

NOTICE: Mixing ELC with other products will reduce the effectiveness of the coolant. This could result in damage to cooling system components.

If Caterpillar products are not available and commercial products must be used, make sure they have passed the Caterpillar EC-1 specification for premixed or concentrate coolants and Caterpillar Extender.

Note: The machine was shipped from the factory with Extended Life Coolant (ELC) in the cooling system.

For information about the addition of Extender to your cooling system, see the Operation and Maintenance Manual, “Cooling System Coolant (ELC) Extender - Add” or consult your Cat dealer.

Drain the coolant whenever the coolant is dirty or whenever the coolant is foaming.

The radiator cap is located under the radiator guard on the top of the engine compartment.

Allow the machine to cool before you change the coolant.

Open the engine access door and raise the radiator guard.

1. Stop the engine to replace 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 belt protection guard, and remove guard to access belt.

4. Loosen the mounting bolt and adjusting bolt, decrease tension in belt.

6. Install new belt. Be sure that the belt is fully seated on the pulleys.

7. Move the alternator until the correct tension 534 ± 22 N·m (120 ± 5 lb) is reached.

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.

Diesel Exhaust Fluid Filter - Replace

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

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.

Sign off on the pressure release procedure

Note: The cover for the cab air filter is on the lefthand side of the machine behind the cab.
