Caterpillar Excavator 345D

Clean the battery surface with a clean cloth. Keep the terminals clean and keep the terminals coated with petroleum jelly. Install the post cover after you coat the terminal post with petroleum jelly

Tighten the hold-downs for the battery in order to prevent the batteries from moving during machine operation.

Rollover Protective Structure (ROPS) - Inspect

Inspect the ROPS for loose bolts or for damaged bolts. Replace any damaged bolts or missing bolts with original equipment parts only.

• Tighten the M16 bolt (1) to125 ± 20 N·m (92 ± 15 lb ft).

• Tighten the M24 bolt (2) to 425 ± 50 N·m (315 ± 40 lb ft).

Do not straighten the ROPS. Do not repair the ROPS by welding reinforcement plates to the ROPS.

Hydraulic System Oil Filter (Case Drain) - Replace

1. Open the access door on the right side of the machine.

2. Clean the area in order to keep dirt out of the filter base.

3. Remove the used case drain filter from the filter base.

Note: Dispose of used filters according to local regulations.

5. Coat the seal of a new case drain filter with clean hydraulic oil.

6. Install the new case drain filter by hand.

Instructions for the installation of the filter are printed on the side of each Caterpillar spin-on filter. For non-Caterpillar filters, refer to the installation instructions that are provided by the supplier of the filter.

Cooling System Coolant Level - Check 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.

Remove cooling system pressure cap slowly to relieve pressure only when engine is stopped and cooling system pressure cap is cool enough to touch with your bare hand.

Do not attempt to tighten hose connections when the coolant is hot, the hose can come off causing burns.

Cooling System Coolant Additive contains alkali. Avoid contact with skin and eyes.

1. Open the access doors on the left side of the machine

2. Maintain the coolant level between the marks on the coolant reservoir.

Note: Refer to Operation and Maintenance Manual, “General Hazard Information” for information that pertains to containing fluid spillage.

NOTICE: Do not change the coolant until you read and understand the material in the Cooling System Specifications section.

NOTICE: Mixing Extended Life Coolant (ELC) with other products reduces the effectiveness of the coolant and shortens coolant life.

Use only Caterpillar products or commercial products that have passed the Caterpillar EC-1 specifications for premixed or concentrate coolants.

Use only Caterpillar Extender with Caterpillar ELC.

Cooling System Coolant Sample (Level 2) - Obtain

Refer to Operation and Maintenance Manual, “Cooling System Coolant Sample (Level 1) - Obtain” for the guidelines for proper sampling of the coolant.

Obtain the sample of the coolant as close as possible to the recommended sampling interval. Supplies for collecting samples can be obtained from your Cat dealer.

Sample obtained for Level 2 analysis?

Submit the sample for Level 2 analysis.

For additional information about coolant analysis, refer to Special Publication, SEBU6250, “Caterpillar Machine Fluids Recommendations” or consult your Cat dealer.
