Dismantle of the pump of a servoupravleniye

If because of installation works in a motive compartment it is necessary to dismantle the pump, its hoses remain connected in order that dirt did not get to hydraulic system. If it is necessary to disconnect hoses from the pump, extreme care in work is necessary. Even the smallest parts of dirt in hydraulic liquid can cause functional violations.

  9. Unscrew the pump together with an arm.
  10. For all: if it is possible, leave hydraulic hoses connected, and put the pump together with hoses in a motive compartment (with the 6-cylinder engine it will not turn out).
  11. If hoses are removed, it needs to be made before dismantle of the pump.
  12. Observe absolute purity!
