1546775 Ball Stud | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta ball stud is a precision valve-train service component used in the rocker mechanism and valve train. It is manufactured to the original Volvo Penta dimensions and interface requirements so the valve train retains its specified geometry, clearance and load path. In service, it provides a spherical contact and adjustment point within the rocker/valve mechanism. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1546775 against the installed assembly before ordering.

🚤 Compatibility

• Engine Family: D, TWD, TAD

🔌 Function

The ball stud provides a spherical bearing surface that a socket-ended linkage or strut clips onto, allowing angular movement while holding the connection in place. It keeps the attached fuel system linkage correctly located and free to articulate through its travel.

⚠️ Common Signs of Failure

• Excessive play or rattling where the socket meets the ball
• Visible wear flats, scoring or reduced ball diameter
• Linkage or strut popping off the stud in service
• Corrosion or pitting on the ball surface
• Loose, stripped or damaged threads allowing the stud to back out

🛠️ Service Notes

• Clean the threads and the seat before fitting, and fit a new stud rather than one whose ball is scored, flattened or worn down
• Tighten to the figure in the workshop manual for your engine and use thread-locking compound only where the manual calls for it; a ball stud that works loose will damage its mounting
• Keep the ball smooth and lightly greased, unless the socket fitting onto it is a dry type that the manual says must not be lubricated
• Press the socket on squarely by hand or with the proper tool — never hammer a gas strut or linkage socket onto the ball
• Check that the strut or linkage moves through its full travel without binding or fouling before putting it back into service
