20459142 Stop Washer | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta stop washer from the Engine group, weighing 0.06 kg. It is one of three stop washers listed for this assembly alongside the standard size 20459149 and the 0.20 mm oversize 20459148, but no grade marking is published against this one, so it has to be matched on measured thickness and part number rather than on appearance.
