Case drain filter

Case drain filter (1) receives case drain oil from the following components.

  • Right travel motor

  • Left travel motor

  • Swing motor

  • Main hydraulic pump (right pump and left pump)

Case drain oil flow from the right travel motor, the left travel motor and the swing motor are combined at the swivel. The case drain oil flow from these components then flows to the case drain filter. The case drain oil from the main hydraulic pump flows to the case drain filter. Return oil then flows from the case drain filter to the hydraulic tank.
