LOCKING MECHANISM (YOKE TIPS, LOCK
PINS AND KINGPIN CONTACT AREA)
1. Proper Lubrication Method:
a.
Using water-resistant lithium-based
grease, lubricate (A) the yoke tips
where contact is made with the
locks and top plate casting, (B) cam
profile, (C) yoke shaft in area that
slides in and out of the top plate
casting, (D) secondary lock where
contact is made with the cam plate,
(E) release handle, and (F) lock
jaws where contact is made with
the kingpin
(Figure 38)
.
b.
Using a light oil, lubricate the (G)
cam pivot point
(Figure 38)
.
If equipped with air release, follow Steps “c”
through “h” for lubrication of the air cylinder.
c.
Inspect the air cylinder tube and
shaft for dents, bending, or other
damage and replace as necessary.
d.
Activate the air cylinder control
to extend the piston and shaft to
its full travel length
(Figure 39)
.
e.
Clean the 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.
f.
De-activate the air cylinder.
g.
Remove the supply air line and
add two to four (2-4) drops of air
tool oil to the cylinder through
the supply fitting. Re-install the
supply air line
(Figure 40)
.
h.
Activate and de-activate the air
cylinder two to three (2-3) times
to work the air tool oil into the
cylinder and onto the piston and
verify proper operation.
2. As-Needed Lubrication:
Clean and lubricate the locking
mechanism if operational difficulties
arise during the service life of the
fifth wheel (i.e., problems with
coupling, uncoupling, or pulling the
release handle)
(Figure 41).
