845009 Spring | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta spring from the Fuel System group, weighing 0.036 kg and listed for 181 applications across the MD, TMD, D, TD, AQD and TAMD series engines. It consolidates three earlier numbers, 239041, 845075 and 845026, one of which was catalogued as an O-ring rather than a spring — so a search on the old number can be misleading.

🚤 Compatibility

• Engine Family: MD, TMD, D, TD, AQD, TAMD, TWD, TID, THAMD, TAD

⚙️ Key Features

• 0.036 kg
• 181 applications across six engine series
• Consolidates 239041, 845075 and 845026
• One superseded number was previously catalogued as an O-ring

🔌 Function

Applies a controlled return load to the component it works against, holding or resetting it to position.

⚠️ Common Signs of Failure

• Sluggish or lazy return of the part the spring loads
• Spring collapsed, taken a set or noticeably shorter than a new one
• Broken coil or a ground flat end
• Rust pitting and scaling along the coils
• Erratic running or hunting traced to weak spring load

🛠️ Service Notes

• Compare against a new spring rather than judging by eye — a spring that has taken a set still looks serviceable
• Because it replaces three earlier numbers including one listed as an O-ring, confirm the assembly needs a spring before ordering by an old reference
