⚙️ Key Features

  • Cylinder-head stud for D12 and TAD12 engines
  • 0.113 kg
  • Supersedes 8170626, which was catalogued as a flange screw - the replacement is a stud, so the fastening arrangement changes
  • Listed for 15 applications across the D range

🔌 Function

Locates the cylinder head accurately and gives controlled thread engagement in the block, working with the position-specific head bolts to hold the joint.

⚠️ Common Signs of Failure

  • Combustion or coolant leak at the head joint
  • Head fixing that will not gain load as it is tightened
  • Stud found bent, corroded or with a pulled thread
  • Stud found unscrewing from the block with the nut
  • Block thread found damaged or pulled on strip-down

🛠️ Service Notes

  • The number it replaces was catalogued as a flange screw, so the arrangement changes - a stud needs its nut and is set to a protrusion, so check the illustration before ordering by the old number
  • Install to the specified protrusion before the head is torqued, and check the block thread first
