⚙️ 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
