2.1
Structural Components
Sub-Frame
Other than for periodic or special inspections the trailer sub-frame requires no regular
maintenance other than washing. Keeping the trailer clean will help you notice other things such as
cracked welds or corrosion. If your application requires the hauling of corrosives, then frequent
washdowns are very important.
Deck
The deck is the major load-carrying member of the trailer. It requires no regular maintenance
other than a periodic check for broken welds, loose fasteners and corrosion. If the trailer has been
overloaded or in an accident, inspect the tilt deck carefully.
It may be necessary to apply a new coat of wood preservative after decking has aged and
become dry. The best time to apply preservative is during warm weather for better penetration.
Replace decking when necessary. Occasionally check for loose, missing, or broken deck screws.
2.2
Sub-Assembly Components
Pintle Eye or Ball Type Coupling
Check for cracks, loose fasteners and wear. Regularly apply a coating of grease to the contact
areas to prevent accelerated wear.
The fasteners are very important and deserve careful attention. Replace the bolts if they are
damaged in any way and replace the locknuts if worn. Torque the fasteners to 315 to 420 lbs.-ft.
