Installation Notes

  1. Depressurize; lockout/tagout air supply and relieve fluid pressure.
  2. Remove lower from rig; secure in soft-jaw vise and disassemble piston/rod.
  3. Extract worn packings; clean grooves and inspect metal parts for scoring.
  4. Pre-oil leather packings (10–15 minutes); install in OEM order/orientation.
  5. Reassemble to spec; cycle at low pressure to wet and seat the seals.

Pro tip: A brief solvent recirculation at low pressure helps the leather swell uniformly and seal faster.

When to Rebuild / Replace

  • Loss of prime or recurring air entrapment
  • Packing leakage/weep at the wet cup
  • Pressure flutter or unstable fan pattern
  • Frequent flushes required to maintain output
