Introduction

Inspections are the most basic form of condition monitoring. Inspections are easy to do and surprisingly effective at helping you spot equipment health issues. Proactive monitoring and analysis of equipment information will allow Dealers to intervene effectively before problems occur.

Note: Before adjusting product settings to comply with listed baseline TA2 values, consult SIS for the latest specification values.

Power Train System

Reference: Refer to Testing & Adjusting, UENR3095, "Power Train System" for more detail on the following test.

Tire Pressure

The tire inflation pressure for machines that are shipped from the factory is suitable for shipping only. Always obtain the proper tire inflation pressures for your machine from the tire supplier before placing the machine into operation. The recommended tire inflation pressures for the front tires and for the rear tires will vary for each application.

Proper tire inflation pressure and maintenance of the tire inflation pressure is critical for optimum tire life. The tire inflation pressure should always be obtained from the tire supplier due to changes in the technology of tires, equipment, and job applications.

Reference: Refer to the latest edition of Special Publication, "Caterpillar Performance Handbook" for general information on tire inflation pressure.
