Caterpillar Excavator 349F

WARNING: Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.

1. Position one final drive so that oil drain plug (2) is at the bottom.

Note: Refer to Operation and Maintenance Manual, “General Hazard Information” for information on Containing Fluid Spillage.

2. Remove drain plug (2) and level plug (1). Allow the oil to drain into a suitable container.

3. Clean the plugs and inspect the O-ring seals. If wear or damage is evident, replace the drain plug, the level plug, and/or the O-ring seals.

5. Fill the final drive to the bottom of the opening on level plug (1). See Operation and Maintenance Manual, “Lubricant Viscosities” and Operation and Maintenance Manual, “Capacities (Refill)”.

Note: If the oil fills slowly, the fill hole may be blocked by the planetary gear. Rotate the final drive to move the planetary gear away from the fill hole.

WARNING: Engine hood and engine hood parts can be hot while engine is running or immediately after engine shutdown. Hot parts or hot components can cause burns or personal injury. Do not allow these parts to contact your skin, when engine is running or immediately after engine shutdown. Use protective clothing or protective equipment o protect your skin.

WARNING: Personal injury can result from hot coolant, steam and alkali. At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns.

NOTICE: Do not change the coolant until you read and understand the cooling system information in Special Publication, SEBU6250, “Caterpillar Machine Fluids Recommendations”. Failure to do so could result in damage to the cooling system components.

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

Unlatch the engine hood and raise the engine hood.

Slowly loosen the pressure cap that is on the coolant reservoir to release pressure from the cooling system.

Inspect the o-ring of the cooling system pressure cap. If the o-ring is damaged, replace the pressure cap.

Open the rear access door on the left side of the machine.

Park the machine on level ground.

Unlatch the engine hood and raise the engine hood.

Make sure that the cooling system has cooled down. Loosen the cooling system pressure cap slowly in order to relieve system pressure. Remove the pressure cap.

It may be necessary to drain some coolant from the radiator so that Caterpillar Extender can be added to the cooling system.

Add Caterpillar Extended Life Coolant (ELC) to the cooling system.
