20906894 Lock Washer | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Lock Washer - Part Number: 20906894

A genuine Volvo Penta locking washer designed for the specified fastener and joint. Its locking geometry resists rotation or preserves the secured position after tightening, helping maintain preload in an engine environment subject to vibration and temperature cycling.

Correct selection must be confirmed against the complete Volvo Penta product designation, product number and serial number because neighbouring engine variants can use different dimensions, connections or calibration.
