Full model list at the end of this description.

⚙️ Key Features

  • High-strength cylinder-head/rocker assembly flange screw
  • Fourteen used on TAD732GE and TAD733GE
  • Located beside rocker arms and valve-adjusting hardware
  • Requires the specified tightening sequence and torque/angle procedure
  • Must be checked against reuse limits in the workshop manual
  • Engine type: Volvo Penta 7-litre six-cylinder industrial diesel
  • L=75mm (Volvo assembly listing)
  • Quantity varies by assembly, most commonly 7

🔌 Function

Clamps the assigned cylinder-head or rocker-support component at the specified preload.

⚠️ Common Signs of Failure

  • Loss of cylinder-head clamp load
  • Damaged or stretched screw
  • Unable to reach the specified torque/angle
  • Coolant or combustion leakage
  • Rocker support movement

🛠️ Service Notes

  • The integral flange spreads the load and forms the bearing face, so do not add a separate washer unless the workshop manual for your engine specifically calls for one
  • Clean the threads and the seating face before fitting — grit, paint or old sealant under the flange gives a false torque reading and the joint will slacken off in service
  • Where the flange is serrated it must bear directly on clean metal to grip; discard any screw with a deformed flange or damaged serrations rather than reusing it
  • Tighten to the torque and sequence given in the workshop manual for your engine, and treat the screw as single-use where the manual specifies an angle-tightened or stretch fastener
  • Check the thread in the receiving component at the same time; a pulled or corroded thread will not hold a new screw however carefully it is torqued
