    Feed and discharge pumps 1. Relief/safety valve: Examine valve cone and valve seat. 2. Bushings: Exchange the bushings if they are scratched or there is a play between shaft and bushing. 3. Wearing seals: Replace the seals if the surface is rough crackled or dented by the impeller.

  • Page 98: Exchange Of Shear Pin Coupling

    8. Axial play: The total axial play (1) must be 0,1 - 0,3 mm. If the play is too large even though the wearing seals have been renewed, it can be compensated by adding a brass leaf liner. Insert the liner at (2). If the play is too small, grind off the bearing holder (3).
  • Page 99 2. Remove the sleeve halves over the shear pin coupling. Remove the pump housing with parts. 3. Drive out the tubular pin (a) from the worm wheel shaft. Use a counterstop. Remove the sleeve (b) from the bearing shield. 4. If the tubular pin in the impeller shaft is broken: drive out the tubular pin.
  • Page 100 5. Check that the lipseal ring (c) is faultless. Should this not be the case, fit a new ring, turned the right way. Fit the new shear pin coupling (d) in the worm wheel shaft together with the sleeve (b). Drive the tubular pin (a) into its position.
  • Page 101 7. Fit the pump housing with parts. Be careful not to damage the lipseal ring. Fit the sleeve halves over the shear pin coupling. 8. Put down the control housing with connecting piece and the lower gasket. Tighten the screws. Fit the sight glass and the upper gasket.
