11700347 Compression Spring | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta compression spring from the Engine system group, supplied as an individual component for engine assembly and overhaul work. It provides the calibrated return force needed to hold or reseat its associated engine component, and is a common replacement item during service because spring tension degrades over time. It is listed for a broad set of D5A, D7A, D7C, MD2010, TD and TAD series diesel engines.

🚤 Compatibility

• Engine Family: D, TD, TAD, MD
• HP Range: Approximately 121-300 HP
• Year Range: Approximately 2000-2017, dependent on engine and machine installation

🔌 Function

A compression spring stores energy when compressed and delivers a controlled return force to hold, load or reseat the component it acts against. Maintaining correct spring force is essential for consistent operation of the assembly it is fitted to.

⚠️ Common Signs of Failure

• Reduced free length or visible sag, indicating the spring has lost tension
• Cracks, chips or a fully broken coil
• Corrosion, pitting or scaling on the coil surface
• Associated component slow to return, sticking or not seating fully
• Rattling or knocking noise from the assembly caused by insufficient spring load

🛠️ Service Notes

• Compare the new spring with the one removed for free length and coil condition; a spring that has taken a set or lost length is past its useful life
• Look over the old spring for corrosion pitting, bright rub marks and cracked or broken coil ends, and check whatever it bears against for the same wear
• Never stretch, shorten, grind or heat a spring to alter how it behaves — fit the correct part instead
• Seat the spring squarely in its recess or over its guide with the ends fully home, so it cannot cock over or bind in service
• Where springs work as a group, renew them together so the load stays even across the set
