Maintenance
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 leaking brake fluid. 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 corro-
sion. If the trailer has been overloaded or in an accident, inspect the deck carefully.
Your trailer has one of two types of decking material, either rubber compound or
wood. For wood decks 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.
The rubber compound material requires no particular maintenance.
Replace decking when necessary. Occasionally check for loose, missing, or broken
deck screws.
2.2 Sub-Assembly Components
Coupling
Your trailer has either a pintle eye or ball type coupling. Check for cracks, loose
fasteners and wear. Regularly apply a coating of grease to the hitch contact areas of
the coupling to prevent accelerated wear.
The fasteners for the coupling are very important and deserve careful
attention.Replace the bolts if they are damaged in any way, and replace the locknuts if
worn. Using a torque wrench, torque the fasteners to value shown on the decal near
the coupling on the trailer tongue.
