- Tilt the top plate forward (the front of the fifth wheel
is down) and apply grease to each bearing area through the zerk fittings
located on each side of the top plate just to the front of the bracket
pins. Continue to apply grease until it is coming out of the back
of the bearing. It may be necessary to raise the rear of the fifth
wheel with a pry bar to open up the pocket slightly and allow the
grease to flow through. A substantial amount of grease may be required
initially to fill the reservoir.
Tilt the fifth wheel rearward (the rear of the fifth wheel is down) and repeat the greasing procedure. Rock the top plate back and forth several times to spread the grease over the bearing surface.
- Inspect the trailer kingpin plate and top surface of the fifth wheel to make sure each is properly greased. A liberal coating of grease should be applied to the complete surfaces of both the trailer kingpin plate and the top surface of the fifth wheel.
- Lubricate the fifth wheel prior to opening and closing.
Grease the jaw and wedge with a screwdriver and distribute the grease
along the full length of the jaw and wedge mating surfaces. See Fig.. Open and close the fifth wheel several times to further distribute
the grease.
Lightly oil other moving parts in the fifth wheel.

- Apply grease to the top plate. Spread grease all over the mating surface of the top plate. Be sure the grease pockets built into the top plates are full of grease.
Note: Do not use a lube plate (high density polyethylene) on top of the fifth wheel or on the kingpin instead of grease without prior approval by Fontaine Fifth Wheel. The additional thickness of this material can prevent the proper operation of the fifth wheel and may cause a dangerous condition.
