Position 5th Wheel Assembly for FW-25HL6
Using an overhead hoist and a suitable safety chain, lift the entire 5
carefully onto the tractor frame. Position the assembly so the center of the king pin jaws is in line
with axle(s) center according to the dimensions indicated for your model on Table 2b.
Proper positioning of the 5
wheel plate moves forward (toward the cab) when rising.
You must provide clearance at the back of the tractor cab for the trailer when it is pulling a trailer
having a long king pin setting. If the 5
frame, do not be concerned. You will fix this in a later step. When you are sure the king pin jaws
are positioned in line with your axle(s) center, make chalk marks on the tractor frame at the
following locations:
(NOTE: Make the marks across the top flange for the tractor frame, down the outside, across the
bottom flange, and up the inside of the tractor frame.)
Then, measure from the forward mark A to the very rear of the tractor frame. This is the length of
the steel angle(s) you will need on each side.
