🔌 Function

Provides the hardened face in the head that the valve closes onto and seals against, in an oversize outside diameter for a recut recess.

⚠️ Common Signs of Failure

  • Compression down on one cylinder with hard starting
  • Popping or spitting back through the inlet or exhaust
  • Seat face burnt, pitted or with a channel cut in it
  • Seat loose in its recess or turning
  • Seat cracked across the face

🛠️ Service Notes

  • Seat 420877 is the other oversize seat here at 0.041 kg — this is despite being oversize, so weight is no guide at all
  • Only fit an oversize seat where the recess has actually been machined to suit; measure the recess before ordering
