Pre-Installation
- Find, using service manual or pressure gauge, the pressure of the loader arm circuits (up and
down motion). Refer to manufacturer's manual for information on how to get the pressures and
relieve system pressure.
- Record the pressures
Piston:_____________________________________________________________psi
Rod:_______________________________________________________________psi
- Compare Pressure Sensors to values to ensure the Pressure Sensor rating meets or exceeds
machine values.
- Determine Pressure Sensor mounting locations (see Figure 5). This is generally an adapter
between the steel tubes coming from the main control valve to a hose connected to the lifting
cylinders.
- Record Adapter size and type
Piston Hose connection size_______________________________________________
Rod Hose connection size_________________________________________________
- Compare the adapters in the kit to ensure they are of the same size and type. See Appendix C.
