A170309 Spacer is a steel dowel-style bushing used as an engine-mount spacer to position the upper-bolt holes on CASE/CNH engine-mount assemblies. It measures 13.41 mm inside diameter, 18 mm outside diameter, and is 13.25 mm long, a dedicated spacer that fits the upper-bolt hole geometry. Manufactured as a steel spacer, it is specified for CASE Construction equipment and appears in engine-mounting kits for models such as the CASE 570LXT backhoe and 580L Series 2. In service, the spacer provides the correct clearance between the engine mount and mounting bracket, locating components and distributing load across the bolt holes.
