1. Remove old grease and debris from all
fifth wheel-to-trailer contact surfaces.
Apply new water-resistant lithium-based
grease to all fifth wheel-to-trailer contact
surfaces (Figures 18 and 19).
2. Using water-resistant lithium-based
grease, lubricate jaw where contact is
made with kingpin. Also lubricate where
lock contacts casting (Figure 19).
3. Using a light oil, lubricate release
handle pivot (Figure 19).
If fifth wheel is air release equipped, follow
Steps 4-8 for lubrication of the air cylinder.
4. Activate air cylinder control to extend
piston and shaft to its full travel
(Figure 20).
5. Clean exposed piston shaft with penetrating
oil and a clean shop towel. Do not use
any abrasives on the exposed shaft as
they could damage the piston shaft.
6. De-activate the air cylinder.
7. Remove supply air line and add 2-4
drops of air tool oil to cylinder through
the supply fitting. Reinstall supply air
line (Figure 21).
8. Activate and de-activate air cylinder 2-3
times to work air tool oil into cylinder
and onto piston and verify proper operation.
