CHECKING THE OPERATION OF THE FIFTH WHEEL continued
Check the Mounting Brackets Before
Remounting the Top Plate:
1. Inspect the brackets for cracks or damage, and
replace if necessary.
2. Check the rubber bushings for wear.
Replace if necessary.
3. Apply grease to the top bearing surface of the
mounting bracket before remounting the top plate.
4. Inspect the bracket pins (or bolts, depending on the
construction of your fifth wheel) for wear. Replace,
if necessary, using the same configuration as
was removed when the fifth wheel was disassembled.
Periodic Maintenance and Adjustment:
1. Lubricate the lock periodically by greasing through the
fittings in the lock pins.
2. Lubricate the top plate and brackets by greasing
through the two fittings on the sides of the fifth wheel.
3. For maximum service life, the fifth wheel should be
steam cleaned, inspected, and adjusted — as necessary
— every 30,000 miles (50,000 km).
