Renewing reservoir for motor/pump unit

Special tools and workshop equipment required

• Hot air blower, e.g. -V.A.G 1416-
• Protective gloves (commercially available)
• Rubber head hammer (commercially available)

Removing oil container

• Remove hydraulic pump with electric motor ⇒ 6.2 Removing and installing motor/pump unit.

Residual amounts of fluid will remain in the hydraulic pump with electric motor after extracting the hydraulic fluid.

• Seal threaded union for pressure line on hydraulic pump with electric motor.
• Remove bracket from motor/pump unit.

• Open clamp -1- and remove upwards.

• Heat all around lower area of oil container -2- evenly using a hot air blower e.g. -V.A.G 1416-.

• Pull reservoir -2- off motor/pump unit -3-.

Installing oil container

• Place a new seal into the sealing surface of the motor/pump unit ⇒ Electronic parts catalogue “ETKA”.
• Ensure oil seal is seated correctly.

• Heat lower area of new reservoir evenly all around using a hot air blower, e.g. -V.A.G 1416-.

• Fit reservoir -1- onto motor/pump unit -2-.
• Position reservoir so that the union for the return line -arrow A- is vertically over the union for the pressure line -arrow B-.
• Pull reservoir -1- onto motor/pump unit -2- to limit stop.
• Use a rubber head hammer to tap evenly all around the reservoir -1- when doing this, never hit the unions with the hammer.
• Ensure the reservoir is straight (not canted).
• Secure reservoir to motor/pump unit with a new clamp ⇒ Electronic Parts Catalogue “ETKA”.
• Tighten bolt of clamp to specified tightening torque.
• Reconnect return line union to motor/pump unit.
• Fill reservoir to approx. ¹/4 full with hydraulic fluid and check for leaks at transition of reservoir to motor/pump unit.
• Tighten clamp if leaks are found.
• Drain reservoir.

The changing of the reservoir must be documented for reasons of guarantee.

• Mark an area of approx. 15 x 30 mm with a permanent coloured mark -2-, e.g. anti-tamper paint, at the illustrated position.

The mark must cover the reservoir -1-, the clamp -3- and the motor/pump unit -4-.

• Install bracket to motor/pump unit.
• Open unions for return line on reservoir and pressure line on motor/pump unit.
• Install motor/pump unit ⇒ 6.2 Removing and installing motor/pump unit.
