⚙️ Key Features

  • Genuine Volvo Penta OEM valve spring washer
  • OEM part number 20510743
  • Technical distinction: Upper valve-spring washer/retainer used in the D11 cylinder-head valve assembly

🔌 Function

Locates and retains the valve spring on the valve stem so the specified spring force and installed geometry are maintained. Inspect all matched valve-train parts, lubricate contact surfaces, set valve recession/clearance where applicable and recheck after initial operation.

⚠️ Common Signs of Failure

  • Excessive valve-train ticking or changing valve clearance
  • Low compression, misfire or poor starting
  • Uneven valve movement or load sharing
  • Pitted, cracked, worn or distorted contact surfaces
  • Valve, spring or rocker damage caused by incorrect adjustment/retention

🛠️ Service Notes

  • Renew as a set when the valve gear is stripped, and keep the parts for each valve together so nothing is mixed between cylinders
  • Inspect the seating face for cupping, cracking or a wear step before reassembly and renew rather than reuse anything marked
  • Make sure the seat in the head and the face of the washer are clean, with no carbon or swarf trapped underneath
  • Fit the correct way up and the correct way round as shown in the workshop manual for your engine, and check the spring and any seal or shroud sit square before the spring is compressed
  • Once assembled, check by hand that each valve moves freely and seats fully before the engine is turned over
