20554106 Valve Yoke | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta valve yoke is an OEM service component used in the Cylinder-Head Valve Yoke. It is manufactured to the original Volvo Penta dimensional, material and interface requirements for the documented Volvo Penta 16-litre TAD16 industrial diesel application. Technical identification: Valve yoke/caliper transmitting rocker movement evenly to paired valves in the TAD1643VE-B cylinder-head assembly. In service, it retains, adjusts or transmits valve-train movement so the valves open and close at the specified timing and clearance. Selection must be confirmed by OEM part number 20554106, the exact model/product number, serial number and installed assembly configuration.

🔌 Function

Retains, adjusts or transmits valve-train movement so the valves open and close at the specified timing and clearance. 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

• Keep each yoke with its own cylinder and its own way round, noting the orientation before removal — they bed to the valves they have been working on
• Inspect the contact pads, the bore or guide and the adjusting screw and locknut for wear, cupping or scoring; a worn yoke loads one valve harder than the other
• Check the guide or pin the yoke runs on and make sure the yoke slides freely on it with no slop
• Set the yoke so it bears squarely and equally on both valves, then set the valve clearance itself, both exactly to the procedure in the workshop manual for your engine
• Oil the contact faces and guide on assembly and turn the engine over by hand to confirm everything moves cleanly before it is run
