JOST COMPLETE JSK37W OVERHAUL KIT WITH CENTRAL LUBRICATION (SK3121-60Z) is a comprehensive repair set for servicing and overhauling JOST JSK37CW and EAW fifth wheels. Designed for versions equipped with central lubrication, the kit includes a central lubrication hose, horseshoe component set and locking jaw together with the corresponding mounting and fastening parts. These components form part of the mechanism responsible for correctly enclosing and locking the trailer kingpin within the fifth-wheel coupling. The repair kit is intended for the relevant 4-hole configuration and has a total weight of approximately 3.08 kg. By combining several wear-related components in one package, SK3121-60Z is particularly suitable for more extensive fifth-wheel maintenance and overhaul work. Always verify the exact JOST fifth-wheel configuration before installation to ensure the repair kit matches the intended application.
