🔧 Product Description

Genuine Volvo Penta pump piston, 21.990 to 21.995 mm diameter, weighing 0.002 kg and listed for 187 applications across MD, TMD, D, TD, AQD and TWD series engines. The diameter band is the entire specification - it supersedes a 21.984 to 21.989 mm piston, so the sizes are graded and must be matched to the bore.

🚤 Compatibility

  • Engine Family: MD, TMD, D, TD, AQD, TWD, TID, TAMD, THAMD, TAD

⚙️ Key Features

  • Pump piston, 21.990 to 21.995 mm diameter
  • 0.002 kg
  • Listed for 187 applications across MD, TMD, D, TD, AQD and TWD series engines
  • Supersedes 240546, 240550 and 25152
  • One of the numbers it replaces was a 21.984 to 21.989 mm piston, so the sizes are graded

🔌 Function

Slides in its bore to generate the pumping stroke in the fuel system, and the close diameter fit is what lets it build pressure without leaking past.

⚠️ Common Signs of Failure

  • Fuel pressure or delivery falling away
  • Hard starting and poor running under load
  • Piston found scuffed, scored or picked up on its working face
  • Varnish or lacquer deposits making the piston sticky in the bore
  • Rust or pitting from water contamination in the fuel

🛠️ Service Notes

  • The diameter band is the entire specification, and the sizes are graded - measure the bore and order the matching piston rather than the previous number
  • Trace and cure water or dirt in the fuel before fitting, since that is what scored the old one
