🔌 Function

⚠️ Common Signs of Failure

  • Scoring or heat discolouration
  • Excessive shaft end play
  • Gear noise
  • Washer distorted or worn
  • Incorrect bearing preload

🛠️ Service Notes

  • Check you are fitting the same type of washer that came out — plain, hardened, sealing and locking washers are not interchangeable, and the wrong one either fails to seal or fails to hold
  • Treat sealing washers on fuel, oil and coolant unions as single-use; they seal by deforming onto the faces, so a used one will not seal reliably a second time
  • Clean the seating faces and make sure the washer sits flat and square, fully under the head or nut, before tightening — a washer trapped on a chamfer or edge will crush unevenly
  • Tighten the fastener to the figure given in the workshop manual for your engine, and account for every washer on reassembly so none is left loose inside a housing or the engine bay
