Full model list at the end of this description.

⚙️ Key Features

  • Oil-resistant front-cover service gasket
  • Used beside oil filler pipe 20412347
  • Associated with dipstick guide tube 20405644 and filler cap 20405835
  • Confirmed across D5/D7 lubricating-system arrangements
  • Included in related overhaul seal lists
  • Engine type: Volvo Penta 5- and 7-litre industrial diesel

🔌 Function

Seals the front-cover service joint around the oil filler and dipstick guide components.

⚠️ Common Signs of Failure

  • Engine-oil seepage at the joint
  • Gasket hardening or cracking
  • Dust entering the filler area
  • Loose service cover
  • Leakage after guide-tube or filler service

🛠️ Service Notes

  • Fit a new gasket every time the joint is disturbed — a gasket takes a permanent set once it has been torqued and will not seal reliably a second time
  • Scrape both faces back to clean bare metal, keeping the blade at a shallow angle so it lifts the old material without gouging the surface, and use a plastic scraper on aluminium castings
  • Check the faces for flatness, cracks and corrosion pitting, and make sure no old gasket, carbon or hardened sealant is left in the corners or around the bolt holes
  • Fit the gasket dry unless the workshop manual for your engine calls for a sealant, and then only the type it specifies — surplus sealant squeezes out into oil, coolant and fuel passages
  • Draw the fasteners down progressively in the sequence and to the torque given in the manual for your engine, and recheck after the first heat cycle where the manual asks for it
