1586922 Tension Spring | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta tension spring from the Engine Controls group, specified for use with part 866652. It provides the return tension within the throttle/control linkage arrangement on TAMD63 and TAMD72/73 series marine diesel engines. A small but critical component, it keeps linkage travel positive and prevents slack in the control mechanism.

• Engine Family: TAMD
• HP Range: Approximately 370 HP

🔌 Function

The tension spring applies constant return force to the engine control linkage so the mechanism returns cleanly to its rest position. It removes free play in the linkage, keeping throttle or control movement precise and repeatable.

⚠️ Common Signs of Failure

• Control lever or linkage fails to return fully to its rest position
• Sloppy or delayed throttle response due to lost spring tension
• Visible corrosion, pitting or stretching of the spring coils
• Broken or detached spring causing the linkage to hang loose
• Erratic or inconsistent engine speed control at the helm

🛠️ Service Notes

• Fitted with linkage part 866652 — check that component's condition at the same time, since a return spring rarely fails without a cause upstream of it
• Fit the spring the same way round as the one removed and confirm the linkage moves freely by hand afterwards, with no slack at the control lever
• Inspect the anchor points for corrosion or wear, since that is where these small return springs usually break

📦 Condition
