1545257 Shoulder Screw | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta shoulder screw in the late-type specification, used as a precision fastener on Volvo Penta industrial and marine diesel engines. The late-type designation is what separates this screw from the earlier version, so it should be matched to the build standard of the engine being serviced. It fits a broad spread of TD, TID, TWD, THD and TAD series engines.

🔌 Function

A shoulder screw provides a precisely sized unthreaded shoulder that acts as a locating or pivot surface while the threaded end clamps the assembly together. It secures the component in position and maintains correct alignment and clearance under running loads.

⚠️ Common Signs of Failure

• Thread damage, galling or stripping that prevents correct torque being reached
• Wear or scoring on the shoulder causing play in the located component
• Corrosion or seizing making removal difficult and risking breakage
• Stretched, bent or snapped screw after over-torquing or fatigue
• Repeated loosening of the joint or fretting marks around the fastener seat

🛠️ Service Notes

• Check shoulder diameter, threads and the band pivot surfaces before reuse.
• Use the specified washer/nut arrangement and tightening value so the band is secure without binding or distortion.
