1. Slide the assembly up around the frame until the bolt hits the bottom
of the trailer frame with the mounting bolts facing out.
2. Insert the second 3/8” x 3-1/2” bolt through the open hole closest to
the top of the trailer frame. (Figure 10)
3. Insert the bolt head into the slot and add a 3/8” lock washer and
thread a 3/8” nut onto the end of the bolt.
No Gaps
For either typical or upside-down installation there should not be a gap
between the trailer frame and the link plate bolts either above or below
the trailer frame. Move electrical or propane lines if necessary. (Figures
11a-11d)
Pinch the link plates flat against the sides of the trailer frame, and hand
tighten both nuts. (Figure 12, 13)
When the nuts have been tightened by hand and both link plates are held
flat against the frame, use a torque wrench to tighten all the link plate
bolts to 27 ft-lb.
L-bracket Installation
Place the L-bracket onto the outside link plate with the bolts in the two
middle holes. Thread on the nylock nuts and hand tighten them until the
L-brackets are held firmly in place. (Figures 14, 15)
Step 5 – Install Spring Arms
The e2 4.5k trunnion arms are NOT side specific.
Insert the spring arm into hitch head and line the knuckle holes with the
corresponding holes in the head. (Figure 16)
Place the ¾” retaining pin through the holes and secure with the cotter
pin.
Lubricate the pin and knuckles frequently.
