Stedman’s hydraulic shim kits help eliminate wrench turning and maintain gap settings on Stedman crushers, the company says. Kits include shims, lift-bridge weldments and hydraulic cylinders for apron assemblies. To add shims, perform lockout/tagout procedures and raise the apron using the hydraulic cylinder. Unlock shim fasteners, add or remove the needed shims and lock the fasteners. Stedman, (800) 262-5401
