12. Fifth Wheel Lubrication

IMPORTANT: 

Fifth wheel lubrication 

is necessary to get the 

maximum service life 

from the FW35 series 

fifth wheel. Perform the 

following procedures at 

the intervals listed.

   Lubricate the locking mechanism every 

three (3) months or 30,000 miles. 

   Thoroughly clean the locking mechanism 

every six (6) months or 60,000 miles.

IMPORTANT: 

For fifth wheels that 

operate in snowy or 

icy winter conditions, 

lubrication should 

be performed every 

spring in addition to 

routine lubrication (as 

noted above) to ensure 

optimum operation.

12.1  Proper Lubrication Method

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 

(Figure 34)

.

2.  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 35)

. 

3.  Using a light oil, lubricate the (G) cam 

pivot point 

(Figure 35)
