🔧 Product Description

Genuine Volvo Penta cylinder head from the Engine group, weighing 37.195 kg and listed for four applications across TWD and TD series engines. It supersedes part number 477593, which was listed earlier only as a cylinder head spare part. At over 37 kg this is a freight item needing lifting equipment, and the second head in this listing, 477833, weighs 36.106 kg with no published fitment.

⚙️ Key Features

  • 37.195 kg, freight only and needs lifting gear
  • Supersedes 477593, previously listed as a cylinder head spare part
  • Four applications across TWD and TD engines
  • The other head here, 477833, weighs 36.106 kg with no published fitment
  • 2 used per assembly

🔌 Function

Closes the top of the cylinders and carries the valves, seats, guides and gas passages, containing combustion pressure and routing coolant around the ports.

⚠️ Common Signs of Failure

  • Coolant loss with no external leak, or bubbles and pressure in the header tank
  • White smoke or coolant in the oil after a gasket failure
  • Compression loss, hard starting and low power on one cylinder
  • Cracks between valve seats or into a coolant passage
  • Head face corroded, eroded or out of flat on measurement

🛠️ Service Notes

  • Check the head face for flatness and pressure test for cracks before deciding whether a used head can be saved
  • Renew the head gasket, head bolts where they are stretch type, and the valve stem seals, and check liner protrusion before fitting
  • Establish why the previous head failed, since a warped head is usually the result of an overheat that needs its own investigation
