🔧 Product Description

Genuine Volvo Penta valve seat in the standard size, marked D and listed against 838601, weighing 0.034 kg and covering 27 applications across AD, D, TMD, TD, TAMD and MD series engines. It supersedes 838607. Four valve seats appear in this run in graded sizes, and their published weights do not follow the sizes - order by the size marking and the measured seat, never by mass.

🚤 Compatibility

  • Engine Family: AD, D, TMD, TD, TAMD, MD

Full model list at the end of this description.

⚙️ Key Features

  • Standard size, marked D, listed against 838601
  • Supersedes 838607
  • 0.034 kg
  • 27 applications across six engine series

🔌 Function

Provides the hardened annular face in the cylinder head that the valve closes against to seal the combustion chamber.

⚠️ Common Signs of Failure

  • Compression loss and hard starting on one cylinder
  • Burnt or blowing sound at the valve on a compression test
  • Valve clearances closing up between services
  • Seat recessed, pitted or cracked on inspection
  • Seat found loose or dropped in the head

🛠️ Service Notes

  • Order by the size marking, not by published weight - the graded seats here do not separate by mass
  • Seats are an interference fit and need the head machining and the valve recut to match
  • Check the guide for wear at the same time, as a worn guide is what usually pounds a seat out
