Vane pump

Vane pump servicing work is not envisaged. Replace vane pump if fault is found.

In the event of problems, consult Fault Finding No. 10: Running Gear and employ pressure test and leak test to establish cause.

=> Service. Fault-Finding: Running Gear

Notes:

  • ◆ Replacement pumps are supplied without fluid fill. Prior to installation they are therefore to be filled with hydraulic fluid G 002 000 and cranked by hand to avoid the possibility of noise whilst driving or pump damage.
  • ◆ Quantity of fluid in system: 0.7 ... 0.9 l
  • ◆ Do not re-use hydraulic fluid drained off.
  • ◆ Replace sealing rings.
  • ◆ Before removing, mark direction of ribbed belt with chalk or felt-tipped pen. Running a used belt in the opposite direction could destroy it.
