## ⚙️ Key Features

-   Genuine Volvo Penta OEM adjusting screw
-   OEM part number 20551362
-   Technical distinction: Valve-caliper adjusting screw used to set the specified valve or engine-brake clearance

## 🔌 Function

Provides the calibrated adjustment point for valve-yoke or valve-clearance setting. Inspect all matched valve-train parts, lubricate contact surfaces, set valve recession/clearance where applicable and recheck after initial operation.

## ⚠️ Common Signs of Failure

-   Excessive valve-train ticking or changing valve clearance
-   Low compression, misfire or poor starting
-   Uneven valve movement or load sharing
-   Pitted, cracked, worn or distorted contact surfaces
-   Valve, spring or rocker damage caused by incorrect adjustment/retention

## 🛠️ Service Notes

-   Note and record the existing setting before disturbing anything, so you have a reference to return to if needed
-   Release the lock nut fully before turning the screw, then reset the lock nut and re-check the setting — tightening the lock nut usually moves the adjustment
-   Set to the clearance or position given in the workshop manual for your engine using the correct feeler or gauge; do not judge the setting by feel
-   Inspect the tip and the threads and renew any screw with a worn, mushroomed or picked-up tip, because a worn tip makes the setting drift in service
-   Never use an adjusting screw to force a component into position, and carry out a hot re-check after running if the manual for your engine calls for one
