Table 2-3. Propulsion System Troubleshooting.
TEST OR INSPECTION
Throughout propulsion system troubleshooting (Table 2-3), reference is made to right and left
hydraulic propulsion pumps, pilot control valves, etc. These references do not represent
physical location of individual components. They refer to physical locations of systems. For
example, the left hydraulic propulsion pump refers to the hydraulic propulsion pump that
drives the left hand propulsion motor and track.
The following test requires use of a hydraulic system tester per TM 9-4940-468-14. Install
tester in-line at test point indicated. Make sure ratings of all fittings and hoses used are
adequate for maximum pressures and flows being tested.
