⚙️ Key Features

  • Supersedes 430160
  • 0.050 kg
  • 110 applications across the MD, TMD, AQ, TAMD, AD and AQAD series
  • A physical casting plug

🔌 Function

Seals a machining or core hole in a casting, expanding against the bore as it is driven home so the passage behind it is closed off.

⚠️ Common Signs of Failure

  • Coolant or oil seeping from around the plug
  • Plug pushed out or standing proud of the casting
  • Corrosion or scale built up in the plug bore
  • Weeping that only shows once the engine is hot and under pressure

🛠️ Service Notes

  • Clean the bore back to sound metal before fitting, since a corroded bore will not hold a plug
  • Drive the plug in square to the correct depth, and use sealant only where the manual calls for it
