-   Secures the rocker shaft above the cylinder head
-   Works with injector and exhaust rocker arms

-   Engine type: Volvo Penta 12-litre six-cylinder diesel
-   Quantity varies by assembly, most commonly 7

## 🔌 Function

Clamps the rocker shaft and valve-mechanism assembly to the cylinder head.

## ⚠️ Common Signs of Failure

-   Rocker-shaft movement
-   Unable to achieve specified torque
-   Abnormal rocker or valve wear

## 🛠️ 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
