860016 Valve Spring | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta valve spring for the MD22L-A, weighing 0.331 kg and listed for 9 applications across the TMD, MS, TAMD and MD engine series. The camshaft in this listing group, 860017, carries the same MD22L-A designation and the same nine applications, so the two belong to the same valve train.

🔌 Function

Closes the valve and holds it hard against its seat, keeping the follower in contact with the cam through the whole lift cycle.

⚠️ Common Signs of Failure

• Valve bounce or a clatter from the valve gear at higher speeds
• Spring found broken, usually at the end coil
• Coils visibly collapsed, so the spring sits shorter than its fellows
• Free length or fitted load measuring below specification when checked
• Uneven wear on the cam lobes and followers

🛠️ Service Notes

• Check the free length and squareness of every spring against specification while the head is off, not just the one that failed
• Renew springs as a set — a single new spring beside tired ones loads the valve train unevenly
• Fit new stem seals and reset the clearances once the head is rebuilt

📦 Condition
