0387288 JOHNSON SOLENOID ASSEMBLY

Illustration 1 g00104545Attach a "Do Not Operate" warning tag or a similar warning tag to the start switch or to the controls before the engine is serviced or before the engine is repaired. These warning tags (Special Instruction, SEHS7332) are available from your Caterpillar dealer. Attach the warning tags to the engine and to each operator control station. When it is appropriate, disconnect the starting controls.Do not allow unauthorized personnel on the engine, or around the engine when the engine is being serviced.Engine exhaust contains products of combustion which may be harmful to your health. Always start the engine and operate the engine in a well ventilated area. If the engine is in an enclosed area, vent the engine exhaust to the outside.Cautiously remove the following parts. To help prevent spraying or splashing of pressurized fluids, hold a rag over the part that is being removed.
Filler caps
Grease fittings
Pressure taps
Breathers
Drain plugsUse caution when cover plates are removed. Gradually loosen, but do not remove the last two bolts or nuts that are located at opposite ends of the cover plate or the device. Before removing the last two bolts or nuts, pry the cover loose in order to relieve any spring pressure or other pressure that may be present.

Wear a hard hat, protective glasses, and other protective equipment, as required.
When work is performed around an engine that is operating, wear protective devices for ears in order to help prevent damage to hearing.
Do not wear loose clothing or jewelry that can snag on controls or on other parts of the engine.
Ensure that all protective guards and all covers are secured in place on the engine.
Never put maintenance fluids into glass containers. Glass containers can break.
Use all cleaning solutions with care.
Report all necessary repairs.Unless other instructions are provided, perform the maintenance under the following conditions:
The engine is stopped. Ensure that the engine cannot be started.
Ensure that the protective locks or controls are in the applied position.
Disconnect the batteries when maintenance is performed or when the electrical system is serviced. Disconnect the battery ground leads. Tape the leads in order to help prevent sparks.
Do not attempt any repairs that are not understood. Use the proper tools. Replace any equipment that is damaged or repair the equipment.
This unit creates vacuum during operation capable of closing doors if not secured. Use door tie backs and rods to avoid personal injury.
After repairs have been made to the fuel system or repairs have been made to the governor, make provisions to shut off the air supply and the fuel supply to the engine in order to stop the engine in case there is an overspeed upon start-up.
Always start the engine from the operator's station. Never short across the starter terminals or the batteries. The engine neutral start system and/or the electrical system could be damaged.
Never start the engine when the governor linkage is disconnected.Pressure Air and Water
Pressurized air and/or water that is used for cleaning can cause debris and/or hot water to be blown out. This could result in personal injury.When pressure air and/or pressure water is used for cleaning, wear protective clothing, protective shoes, and eye protection. Eye protection includes goggles or a protective face shield.The maximum air pressure for cleaning purposes should be below 205 kPa (30 psi). The maximum water pressure for cleaning purposes should be below 275 kPa (40 psi).Fluid Penetration
Illustration 3 g00687600Always use a board or cardboard when you check for a leak. Leaking fluid that is under pressure can penetrate body tissue. Fluid penetration can cause serious injury and possible death. A pin hole leak can cause severe injury. If fluid is injected into your skin, you must get treatment immediately. Seek treatment from a doctor that is familiar with this type of injury.Containing Fluid Spillage
This unit is equipped with a fluid spill containment basin. The fluid spill containment basin is capable of containing the entire volume of engine oil and coolant. The fluid spill containment basin is also capable of containing a reasonable overflow of the fuel tank. These fluids must be absorbed and collected for proper disposal.This unit is equipped with fluid containment basins on both sides of the base for the fuel tank. These fluid containment basins normally collect water that is drawn in through the fresh air intakes of the package. The fluid containment basins are equipped with drain valves. Fluids that are drained from the fluid containment basins should be disposed of properly.Care must be taken in order to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the engine. Prepare to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Tools and Shop Products Guide" for the following items:
Tools that are suitable for collecting fluids and equipment that is suitable for collecting fluids
Tools that are suitable for containing fluids and equipment that is suitable for containing fluidsObey all local regulations for the disposal of liquids.Asbestos Information
Illustration 4 g00702022Caterpillar equipment and replacement parts that are shipped from Caterpillar are asbestos free. Caterpillar recommends the use of only genuine Caterpillar replacement parts. Use the following guidelines when you handle any replacement parts that contain asbestos or when you handle asbestos debris.Use caution. Avoid inhaling dust that might be generated when you handle components that contain asbestos fibers. Inhaling this dust can be hazardous to your health. The components that may contain asbestos fibers are brake pads, brake bands, lining material, clutch plates, and some gaskets. The asbestos that is used in these components is usually bound in a resin or sealed in some way. Normal handling is not hazardous unless airborne dust that contains asbestos is generated.If dust that may contain asbestos is present, there are several guidelines that should be followed:
Avoid brushing materials that contain asbestos.
Avoid grinding materials that contain asbestos.
Use a wet method in order to clean up asbestos materials.
A vacuum cleaner that is equipped with a high efficiency particulate air filter (HEPA) can also be used.
Use exhaust ventilation on
