Hydraulics Trouble Shooting Guide

The pilot line on the right-hand side of the load-sensing valve is connected to the pressure line at the pump outlet. System pressure shifts the load-sensing valve and directs pressure to reduce the pump stroke so that system pressure drops to the load-sensing setting of 300 psi, as illustrated in Figure 2. · The gearbox should shift and the Hi Gear and Low Gear bits on the diagnostic page should change state. If the gearbox does not shift, it may have internal damage. If the gearbox shifts, refer to these troubleshooting guides for the high and low gear solenoids and the I/O PCB.2. pressure filter blocked As 4 E 1. constant delivery flow is too high 2. unsuitable valve type (ID too small) 3. pressure setting too high 4. response time too long F ing of Hydraulic Fluid 1. suction line leaks 2. fluid level too low 3. wrongly designed reservoir ….

 · The oil pressure sensor is up on the top if its a syncro shuttle or power shift with a plug type fitting.The trans pressure should be between 9.5 - 11 bar depending on temp of oil. If you have a gauge on the test port when you select a gear the pressure will … · Horsepower = Flow x Pressure, so the combination needs to be high enough. The maximum pressure a pump is specified for varies somewhat from pump to pump but is generally in the - psi area. The flow per revolution varies enormously from pump to pump, so when searching for a pump, first look at the flow per revolution or GPM (gallons per ...Hydraulic Flow - High Flow XPS: Maximum Loader Hydraulic Pressure 28 000 kPa 4,061 psi Maximum Loader Hydraulic Flow 121 L/min 32 gal/min Hydraulic Power (calculated) 57 kW 76 hp .

converter transmission on the 524K-II employs smart shift tech-nology to continuously evaluate speed and load conditions, and adjusts clutch-pack engagement to suit. 544K-II and 624K-II feature standard ive-speed transmission with lockup torque converter in gears 2-5, to increase acceleration, speed cycles, and optimize powerThe advantage is a stepless gear ratio (continuously variable speed/torque) and a more flexible control of the gear ratio depending on the load and operating conditions. The hydrostatic transmission is generally limited to around 200 kW maximum power, as the total cost gets too high at higher power compared to a hydrodynamic transmission. · The transmission oil pressure sensor's primary function is to relay information to the ECM that regulates control of the transmission. However, if the switch is damaged or not sending information correctly to the ECM, the transmission may default into "limp" mode. In this case, the transmission will be locked into the "limp" gear, such as a.

2. To keep high pressure fluid out of the low pressure side of the hydrostatic circuitry; Function 2 [A] and Function 2 3. To release high pressure caused by moving forward with a heavy load on the loader, Function 3 [A]. CHARGE OIL FUNCTION 1 Valve Moves for Charge Oil Replacement FUNCTION 2 FUNCTION 3 Valve Stays on Seat to · The pressure recorded is your pressure under wide open throttle. For automatic transmissions, you will need to drive the vehicle and record the pressure as it shifts from gear to gear. The pressure should be much higher than at idle. Figure 6. Make sure you get the correct size gauge for your WOT portion of the test. · and Series Cab and Open Operator Station Tractors are base equipped with a 21.1-gpm main pump and an external gear/constant flow design. Pressure for entire system is established by the function requiring the highest pressure. As demand lessens, so does pump pressure and engine power requirement.

the load automatically remains parallel throughout the lift range. And, like a toolcarrier, the 924H can easily manipulate loads at all heights. High Lift Version Special applications call for special equipment.
