Step 4
Raise the liftgate by lifting under the main section of the folded platform with a forklift.
Make sure the platform is clamped securely to the forks. With the trunnion and liftarms
hanging from the platform, the platform rib and pivot assembly should make firm contact.
The installer may need to rotate the trunnion, as shown, to make this contact. Tack weld
the platform hinge to the pivot assembly to maintain contact. See figure 4.
Step 5
Using a forklift or crane, center and position liftgate behind vehicle and jack trunnion into
position. See figure 5 and 1 for “A” dimension.
Note: Do Not
connect hydraulic lines at
this time, the M series liftgates are pre-assembled with cylinder and pump mounted. On
certain installations, for instance a truck with a rear fuel tank, the pump may get in the
way of obtaining the proper “A” dimension. In most of these cases,
Except
for the 50" to
54" bed height range, where the “A” dimension is 25.00, the pump may be removed and
then mounted to the second, more rearward, set of holes in the pump mounting bracket
to provide more clearance.
Note: Do Not
move pump when the “A” dimension is 25.00
because the platform will not stow properly.
Step 6
Cut a small post or similar item to the correct length and place it under the platform so
the platform and payload area are at the same height. Place barrels or other protective
equipment under the platform so that the gate will not accidentally fall and injure some-
one.
