MODEL MG 5050 MARINE TRANSMISSION Caterpillar


Marine Transmission

Usage:

When the words "use again" are in the description, the specification given can be used to determine if a part can be used again if the part is equal to or within the specification given, use the part again

When the word "permissible" is in the description, the specification given is the "maximum or minimum" tolerance permitted before adjustment, repair and/or new parts are needed.

A comparison can be made between the measurements of a worn part and the specifications of a new part to find the amount of wear. A part that is worn can be safe to use if an estimate of the remainder of its service life is good. If a short service life is expected, replace the part.

Safety

Do not wear loose clothing and jewelry whenever working around engines or driven equipment.

Stop engine before making adjustments or repairs to the engine or driven equipment unless specified otherwise.

Attach a "DO NOT OPERATE" or similar warning tag on the start switch, or start button, before servicing the marine transmission. These tags, Form SEHS7332, are available from your Caterpillar dealer.

Be sure the remote starting system is inoperative on the engine driving the marine transmission to be serviced.

Disconnect and tape the engine battery ground lead before working on an engine or marine transmission to prevent accidental starting.

To prevent injury, install guards over all exposed drive shafts, pulleys or any application with exposed rotating parts.

Relieve all pressure in air, oil, fuel or water systems before any lines, fittings or related items are disconnected or removed. Be alert for possible pressure when disconnecting any device from a system that utilizes pressure. Do not check for pressure leaks with your hand.

Always use a piece of cardboard or something similar when checking for a leak. Escaping fluid under pressure, even a pin-hole size leak, can penetrate body tissue, causing serious injury, and possible death. If fluid is injected into your skin, the injury must be treated by a doctor familiar with this type of injury within a few hours.

Use caution when removing cover plates. Gradually loosen (do not remove) the last two bolts or nuts located at opposite ends of the cover or device. Pry cover loose to relieve any spring or other pressure, before removing the last bolts or nuts.

Always use tools that are in good condition and be sure you understand how to use them before performing any service work. Remove all tools, electrical cords and any other loose items from the marine transmission before operating.

Wear a hard hat, face shield, clothing, shoes, respirator or other protective items when necessary.

When using pressure air, wear protective glasses and protective clothing.

Wear hearing protection devices to prevent hearing damage, if working inside an enclosed engine room with engine running.

Fire Or Explosion Prevention

Fire may result from lubricating oil or fuel sprayed on hot surfaces causing personal injury and property damage. Inspect all lines and tubes for wear or deterioration. They must be routed, supported or clamped securely. Tighten all connections to the recommended torque.

Make repairs as soon as any fuel or oil leak is discovered.

Collect drained liquids and clean up all oil, fuel or coolant spills.

Store oil rags in proper containers. Do not leave rags on engine.

Accumulated grease and oil on equipment is a fires hazard. Remove the grease, oil and debris at least every 1,000 hours and each time any significant quantity of oil is spilled.

Never store flammable liquids near the engine.

Keep all lubricants stored in properly marked containers.

Provide adequate and safe waste oil disposal.

Oil and fuel filters must be properly installed and tightened when being changed.

Diesel fuel and all lubricants are flammable. Do not weld on pipes or tubes that contain fuel or lubricants. Clean them thoroughly with nonflammable solvent before welding.

Observe NO SMOKING signs.

Loose or damaged lines or tubes that allow oil, fuel or coolant to leak can cause overheating and/or fire.

Do no bend or strike high pressure lines. Do not install bent or damaged lines or tubes. Do not replace steel tubes with copper tubes.

Do not allow debris, dirt and foreign material to accumulate on or around the engine or marine transmission. Overheating or fire could result.

Wiring must be kept in good condition, properly routed and firmly attached. Routinely inspect wiring for wear and deterioration. Loose, unattached, or unnecessary wiring must be eliminated. All wires and cables must be of the recommended gauge and fused if necessary. Do not use smaller gauge wire or bypass fuses.

Tight connections, recommended wiring and cables properly cared for will help prevent arcing or sparking which could cause a fire.

Always have a fire extinguisher on hand and know how to use it. Follow the manufacturer's periodic inspection and maintenance recommendations on its instruction plate or label.

Burn Prevention

Extreme caution should be used whenever draining a lubricant. The lubricant may be hot and could cause personal injury.

Do not touch any part of an operating marine transmission. Allow the marine transmission to cool before any repairs are performed.

Use caution when removing filler caps, grease fittings, pressure taps, breathers or drain plugs. Hold a rag over the cap or plug to prevent being sprayed or splashed by liquids under pressure.

Preparing To Start

Be sure all protective guards and covers are installed. To help prevent an accident caused by parts in rotation, work carefully around them.

Inspect the marine transmission for potential hazards.

Starting

Do not start the engine or move any of the controls if there is a warning tag attached to the controls.

Make sure no one is working on, or close to the engine and marine transmission or in the water near the propeller before starting it.

------ WARNING! ------

Be sure the propeller wake will not cause injury or damage to personnel or property.
