Volvo loader L90 and L120 connecting rod

The connecting rods used in the Volvo L90 and L120 loaders, particularly in the mid-to-late 2000s models equipped with the D6 series engines, possess a distinct design feature that sets them apart from conventional components: they utilize an eccentric, or offset, small end. Unlike a standard connecting rod where the centerline of the piston pin bore aligns perfectly with the centerline of the rod, Volvo engineered these rods with a slight offset. This design is implemented to reduce the side thrust exerted on the piston against the cylinder wall during the power stroke.
