3. During the auto grab function, the transmission grapple control maintains a pressure between 18,271 kPa and 20,684 kPa (2,650 psi and 3,000 psi). The hydraulic pump will operate for a short time to re-pressurize the grapple system at intervals between 20 to 60 seconds depending on oil temperature and valve leakage rates. If the hydraulic pressure drops below 17,237 kPa (2,500 psi) and the CAT monitoring system indicates the auto close function is active, then the pressure sensor is probably faulty. If the Electronic Technician (ET) or the Electronic Control Analyzer Programmer (ECAP) service tools are used, and a pressure sensor value of 58,111 kPa (8,428.23 psi) is observed, either the sensor or the sensor wiring are faulty. Follow the trouble shooting procedure in Service Manual SENR6686 to check the pressure sensor and the associated wiring.4. If the hydraulic pump cycles consistently more often than every one to two minutes (on a machine with no other hydraulic loads), check the hydraulic system for signs of oil leakage.
