1556073 Pin | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta pin is a replaceable locating, spacing or bearing-support component used in the cylinder-head valve-yoke assembly. It is manufactured to the original Volvo Penta dimensions and interface requirements so the supported component retains the specified clearance, spacing and location. In service, it provides the located pivot or retaining point used within the cylinder-head valve-yoke mechanism. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1556073 against the installed assembly before ordering.

🔌 Function

The pin locates and retains mating engine components in their correct relative position, maintaining alignment under operating loads. Correct positioning is essential for the assembled parts to seat and function as designed.

⚠️ Common Signs of Failure

• Visible wear, scoring or flattening on the pin body
• Loose or sloppy fit allowing movement between mated components
• Bending, shearing or deformation from operating loads
• Corrosion or pitting making removal and refitting difficult
• Misalignment or knocking noises from the assembly the pin locates

🛠️ Service Notes

• Check the pin and its bore for wear, ovality, scoring and corrosion; a worn pin in a worn bore shows up as lost motion in whatever it links
• Fit the pin the correct way round and to the correct depth, driving it with a punch that bears on the pin rather than on the surrounding casting
• Secure it with the same retaining device as originally used — a new split pin, clip or circlip; never reuse a split pin and never straighten and refit a bent pin
• A light smear of a suitable marine grease on assembly slows corrosion and keeps the pin free for next time
• Check that the linkage or component the pin carries moves through its full travel freely once everything is assembled
