The Volvo Penta Disc Spring 872794 is a genuine OEM spring washer designed to provide controlled preload and tension within Volvo Penta sterndrive and engine assemblies. This disc-style spring maintains consistent pressure between components, helping to absorb vibration, compensate for thermal expansion, and prevent loosening under load.

Manufactured from high-strength spring steel, this component is engineered to retain its elasticity and performance in harsh marine environments. It is commonly used in driveline, gear housing, and mounting assemblies where precise tension is required.

Parts Desk Insight

Disc springs are critical in maintaining proper preload in driveline assemblies. If one fails, it can lead to loosening, vibration, and premature wear of expensive components. Always replace them during major service theyre cheap insurance compared to driveline damage.
