Important Safety Information
| |
| Illustration 1 | g02139237 |
Work safely. Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools to perform these functions properly. Safety precautions and warnings are provided in this instruction and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons. Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard. Therefore, the warnings in this publication and the warnings that are on the product are not all inclusive. If a tool, a procedure, a work method, or operating technique that is not recommended by Caterpillar is used, ensure that it is safe for you and for other people to use. Ensure that the product will not be damaged or the product will not be made unsafe by the operation, lubrication, maintenance, or the repair procedures that are used.

Improper operation, lubrication, maintenance or repair of this product can be dangerous and could result in injury or death. Do not operate or perform any lubrication, maintenance or repair on this product, until you have read and understood the operation, lubrication, maintenance and repair information. |
Safety precautions and warnings are provided in this manual and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons.
The hazards are identified by the safety alert symbol which is followed by a signal word such as danger, warning, or caution. The "WARNING" safety alert symbol is shown below.

This safety alert symbol means:
Pay attention!
Become alert!
Your safety is involved.
The message that appears under the safety alert symbol explains the hazard.
Operations that may cause product damage are identified by "NOTICE" labels on the product and in this publication.
Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard. The safety information in this document and the safety information on the machine are not all inclusive. Determine that the tools, procedures, work methods, and operating techniques are safe. Determine that the operation, lubrication, maintenance, and repair procedures will not damage the machine. Also, you must determine that the operation, lubrication, maintenance, and repair procedures will not make the machine unsafe.
The information, the specifications, and the illustrations that exist in this guideline are based on information which was available at the time of publication. The specifications, torques, pressures, measurements, adjustments, illustrations, and other items can change at any time. These changes can affect the service that is given to the product. Obtain the complete, most current information before you start any job. Caterpillar dealers can supply the most current information.
Summary
The information included in this guideline should serve as an aid in fuel injection pump housing test procedure.
Service Letters and Technical Information Bulletins
| NOTICE |
|---|
|
The most recent Service Letters and Technical Information Bulletins that are related to this component shall be reviewed before beginning work. Often Service Letters and Technical Information Bulletins contain upgrades in repair procedures, parts, and safety information that pertain to the parts or components being repaired. |
Replacement Parts
Consult the applicable Parts Identification manual for your engine.

|
When replacement parts are required for this product Caterpillar recommends using Caterpillar replacement parts or parts with equivalent specifications including, but not limited to, physical dimensions, type, strength and material. Failure to heed this warning can lead to premature failures, product damage, personal injury or death. |
Fuel Injection Pump Housing Test Procedure
This test must be performed with the fuel injection pump housing and the fuel at a temperature between
- Disconnect the fuel injection lines and the fuel return line from the pump. Cap all the bonnets and the return line fitting, to prevent leakage when pressure is applied. Fuel injection lines can be modified to cap the bonnets.
- Disconnect the fuel supply lines, and make sure that the pump housing is full of fuel. Connect a pressure gauge and shutoff valve to the supply fitting, as shown in Illustration 1. Connect an air supply to the shutoff valve. Make sure the caps, connections, shutoff valves, and the gauge do not leak.
- Apply
480 kPa (70 psi) air pressure to the pump housing. Close the shutoff valve. - Observe the pressure loss over a period of five minutes. A pump is good if the pressure loss in five minutes is
35 kPa (5 psi) or less.Show/hide table
Illustration 4 g06347442 Locations to Check for Leakage
(7) Check this area of housing
(8) Barrel
(9) Timing spacer - If the pressure loss exceeds
35 kPa (5 psi) in five minutes, remove each of the injection pumps one at a time. Inspect the seal surfaces of the barrel, timing spacer, and housing, as shown in Illustration 4. Check the surface finish of these parts. Make sure that none of these surfaces have any dirt, debris, nicks, cracks, or scratches on them. - Install all the injection pumps in the pump housing. Test the pump housing again for pressure loss.
