CHECKING WN 124-219 VANE WEAR

Rotary vane wear takes place gradually as the pump operates. Measuring the vane height during servicing provides a useful indication of whether the vanes remain within their acceptable operating limit.
When inspecting WN 124-219 vanes, the condition of the pump itself should also be checked for anything that could contribute to accelerated or uneven wear:
✓ Check the complete vane set for even wear
✓ Inspect the rotor slots and internal running surfaces
✓ Check bearings for wear or excessive noise
✓ Inspect the inlet filter and airflow path
✓ Look for excessive carbon dust or contamination
✓ Investigate signs of excessive operating temperature
A new WN 124-219 vane has a height of 16 mm. The minimum wear height is 11 mm. Once the vane height reaches 11 mm, the complete set of five vanes should be replaced.
