CYLINDER GP-ANGLING 1363156 - Caterpillar

You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.This maintenance is to be performed at the interval specified in the Maintenance Schedule for the engine being maintained.Before proceeding with this maintenance, first perform Daily maintenance requirements.Zinc Rods
Zinc rods are inserted in the engine's raw water cooling system to help prevent the corrosive action of salt (sea) water. The reaction of the zinc to the sea (raw) water causes the rods to deteriorate, instead of more critical engine cooling system parts.Therefore, the zinc rods must be inspected every 50 service hours, and replaced when they have deteriorated.Depending on the engine and attachments, their location may be in the oil cooler heat exchanger bonnet, raw water heat exchanger bonnet, aftercooler lines, raw water pump and/or in the raw water lines.Inspect
Removing Old Zinc Rods
1. Remove and observe condition of all zinc rods. They are painted red for easy identification. 2. Tap the zinc rods lightly with a hammer. If a rod has deteriorated, or flakes apart when tapped, install a new zinc rod.Installing New Zinc Rods
1. Unscrew or drill the existing rod from the plug base.2. Apply 9S3263 Thread Lock to the internal threads of the plug(s) holding the zinc rod(s). Install new rod(s) in the plug base(s).3. Coat the external pipe threads with 5P3413 Pipe Sealant and install the plug(s) into their proper locations in the raw water system.Marine Gear
Drain Oil and Replace Filter
With the oil warm and the engine stopped, drain the oil and replace oil filter element on a new or rebuilt marine gear at the first 50 Hour interval to ensure draining of possible large debris and particles from the oil and gear housing.Drain and change filter element with the oil warm and the engine stopped to allow for the draining of waste particles that are suspended in the oil. Suspended waste particles will settle on the bottom and will not be removed with the draining oil if the oil is cold.Failure to follow this recommended procedure would result in these waste particles being recirculated through your marine gear system with the new oil. Refer to the topic in the Every 1000 Hour maintenance interval in this manual for instructions and procedure.For lubrication and maintenance requirements for your marine gear model, refer to the OEM and/or vessel manufacturer's recommendations.Marine Gear Operation, Maintenance, Warranty & Parts Support
Caterpillar encourages customers to refer to their Caterpillar dealer and/or marine gear OEM dealer for information regarding operation and maintenance for the transmission.All warranty and parts support for the marine gear (including installation and service problem resolution) will be the responsibility of the selling dealer and the marine gear OEM.Air Tank
Drain Water and Sediment
When required, or at least on a weekly basis, open the drain valve on the air tank and drain the water and sediment. Close the valve.
