Safety Precautions
Do not operate or work on this engine unless you have read and understand the instructions and warnings in the Operation and Maintenance Manual. Failure to follow the instructions or heed the warnings could result in injury or death. Contact any Caterpillar dealer for replacement manuals. Proper care is your responsibility.
Keep hands clear of fan and belts while engine is running.
Making contact with a running engine can cause burns from hot parts and can cause injury from rotating parts.When working on an engine that is running, avoid contact with hot parts and rotating parts.
Specifications
Compare the inlet manifold pressure to the pressure given in the TMIIntroduction
The efficiency of an engine can be checked by comparing the pressure in the inlet manifold with the information given in the Technical Marketing Information (TMI). This inlet manifold pressure test is used when there is a decrease of horsepower from the engine, with no sign of a problem with the engine.The correct pressure for the inlet manifold is listed in the TMI. The correct pressure is also on the Fuel Setting and the related Service Information System. Development of this information is performed under the following conditions:
99 kPa (29.7 in Hg) dry barometric pressure
29 °C (85 °F) outside air temperature
35 API rated fuelOn a turbocharged, aftercooled engine, a change in the fuel rating will change the horsepower. A change in the fuel rating will change the inlet manifold pressure. If the fuel is rated above 35 API, the inlet manifold pressure can be less than the pressure given in the TMI. The pressure will also be less than the pressure that is listed on the Fuel Setting and the Related Service Information System. If the fuel is rated below 35 API, the inlet manifold pressure can be more than the pressure listed in the TMI. The pressure will also be more than the pressure that is listed on the Fuel Setting and the Related Service Information System.Required Tools
