Inspection
In this training, many pages scroll. To proceed to next step you must scroll to the bottom before the button is visible.
WARNING! Do not use any fifth wheel that has
damaged components or fails to operate properly.
Fontaine recommends that preventative maintenance be performed after 90 days or 50,000 miles, whichever comes first and every 90 days or 50,000 miles thereafter. Note: P.M. intervals are recommended based on standard duty applications. Applications more severe than standard duty may require different P.M. intervals to ensure peak performance.
Using a suitable solvent, degrease the fifth wheel and mounting brackets and inspect for:
1. Cracks in the fifth wheel assembly, mounting brackets, and mounting parts.
2. Wear and/or damage to moving parts.
3. Loose nuts and bolts in the fifth wheel and in the mounting hardware.
4. Securely fastened and properly working springs.
