⚙️ Key Features

  • Genuine Volvo Penta moulded O-ring
  • Oil- and temperature-resistant elastomer
  • Used in the TAD540VE/TAD541VE/TAD542VE oil module
  • Housing 22565707 uses quantity two
  • Single-use seal; lubricate and install without twisting
  • Engine type: 5.1-litre inline four-cylinder turbocharged industrial diesel

🔌 Function

Seals the internal oil passages at the housing/cooler interface and prevents external oil leakage or cross-leakage.

⚠️ Common Signs of Failure

  • Oil seepage around the housing joint
  • Flattened, hardened or cut O-ring
  • Oil-pressure loss
  • Oil contamination around adjoining passages
  • Leak recurrence caused by a scratched groove or twisted seal

🛠️ Service Notes

  • Always fit a new O-ring — never refit one that has been removed, as it has already taken a set in its groove
  • Clean the groove and both sealing faces and check them for nicks, scoring and corrosion pitting; a damaged groove will leak however good the new seal is
  • Smear the ring with a little clean lubricant compatible with the fluid it seals, then roll it into place by hand so it sits untwisted and fully in its groove
  • Never lever an O-ring over a sharp edge or thread with a screwdriver; use a blunt plastic tool and protect any edge the ring has to pass
  • Assemble the joint squarely and tighten to the figure and sequence given in the workshop manual for your engine — over-tightening extrudes the ring and causes the very leak you were curing
