SITRAK C7H G7H HOWO T7H TX7 JOST Fifth-wheel assembly WG9925939003/JSK35DV1-25
Common Wear Parts and Routine Maintenance
1. Locking Jaw (Locking Hook and Latch): The entire assembly requires replacement due to frequent coupling operations or excessive wear.
2. Wear Ring: Secures the kingpin; wear in this component can lead to trailer swaying and abnormal noise.
3. Rubber Bearing: A cushioning pad located at the base of the fifth wheel; it must be replaced promptly if it shows signs of aging or deterioration.
4. Lubrication: The top plate features patterned grease grooves; heavy-duty grease should be applied regularly before operation to ensure smooth lubrication of the locking mechanism and the plate surface.
Key Maintenance Indicators
1. Periodic Lubrication: A comprehensive cleaning and re-application of heavy-duty grease are required every 4,000 km (or every two weeks) for the fifth-wheel top plate surface, the interior of the locking jaw, the handle linkage, and the bottom support leg bearings.
2. Clearance Inspection and Screw Adjustment: If noticeable fore-and-aft movement or abnormal noise occurs while the trailer is in motion, it indicates that clearance has developed between the locking jaw and the trailer kingpin. This model is equipped with an adjustable screw mechanism; by turning the adjustment nut at the front of the fifth wheel, the internal locking block can be moved forward to compensate for excess clearance caused by long-term wear and restore a secure coupling.
