Caterpillar Industrial Engine C9

Cylinder Head Grounding Stud - Inspect/Clean/Tighten

Inspect the OEM harness for good connections and condition.

The electrical grounding stud must have a wire ground to the battery.

Tighten the electrical grounding stud at every oil change.

Ground wires and straps should be combined at engine grounds.

All grounds should be tight and free of corrosion.

If the connections are corroded, clean the connections with a solution of baking soda and water.

Keep the electrical grounding stud and the strap clean and coated with MPGM grease or petroleum jelly.

Fuel System Primary Filter (Water Separator) Element - Replace

Air Tank Moisture and Sediment - Drain

Drain valve opened and moisture and sediment drained?

Cooling System Coolant Level - Check

Coolant level checked and maintained within 13 mm (0.5 inch) of the bottom of the filler pipe?

Cooling system filler cap cleaned and checked for damage?

Cooling system inspected for leaks?

Check the battery charger for proper operation. If the batteries are properly charged, the needle of the ammeter will register near “0” (zero).

The battery charger must not produce excessive current during start-up. Alternatively, the charger must be automatically disconnected for start-up.

If the engine has an alternator, the charger must be automatically disconnected during start-up and during engine operation.

Never disconnect any charging unit circuit or battery circuit cable from the battery when the charging unit is operated. A spark can cause an explosion from the flammable vapor mixture of hydrogen and oxygen that is released from the electrolyte through the battery outlets. Injury to personnel can be the result.

Perform the following procedure to charge the battery:

1. Ensure that the charger is turned OFF.

Warning: This procedure requires trained personnel with PPE!

NOTICE: Always use a designated pump for oil sampling, and use a separate designated pump for coolant sampling.

Note: Level 1 results may indicate a need for Level 2 Analysis.

Enter the coolant sample interval

Enter the information on the label for the sampling bottle

Did you obtain coolant samples directly from the coolant sample port?

Did you place the sample in the mailing tube immediately after obtaining the sample?

Did you avoid collecting samples from expansion bottles and system drains?

Inspect the aftercooler for these items: damaged fins, corrosion, dirt, grease, insects, leaves, oil, and other debris.

Clean the aftercooler, if necessary.

Use pressurized air for removing loose debris.

Use pressurized water for cleaning.

Use a degreaser and steam for removal of oil and grease.

Wash the core with detergent and hot water.

Thoroughly rinse the core with clean water.

After cleaning, start the engine and accelerate the engine to high idle rpm.
