Read the reviewed summary
Inspect and maintain the fifth wheel regularly under its own installation and operating instructions. Conventional, lined and automatic-lubrication designs have different greasing needs; some plates must not be treated like a conventional steel plate. Inspect locking and wearing parts and use approved lubricant where required. There is no single monthly or 10,000 km schedule suitable for every coupling.
