Step 7
Attach mounting plates to truck by means of .62" Grade 8 screws or by a .38 fillet
weld all around. Weld the mounting plates to the trunnion tube all around in the same
manner.
Note:
On installation where narrow underframe members are used, the liftgate mounting
plates will reach these frame members for mounting purposes; however, the space
between the frame members and trunnion now becomes quite large. This lengthy
unsupported area may contribute to undesirable ‘springiness’ under heavy loading.
Many installers when faced with this problem extend the underframe support on the
mounting plate closer to the trunnion by adding a channel section under the existing
frame member as shown in figure 6. On certain equipment such as a lengthened van
body, rebuilt trailer or other altered vehicle, where the underframe stops short of the
end of the vehicle body frame, extra support must be added to avoid any indepen-
dent deflection. See figure 7 for bracing suggestions. Refer to figure 1 for clearances.
Step 8
Fasten the 150 amp circuit breaker provided within 2 ft. of the truck battery. Route the
battery cable from the liftgate toward the circuit breaker. AvOID SHARP CORnERS
AnD HIGH HEAT AREAS. Use cable clips provided to secure the cable to the truck
frame every 2 ft. Cut the cable to the desired Length and strip .88" of the insulation
from the end. Slide the pre-cut heat shrink over the end of the cable. Secure the
cable lug in a vise and apply heat to the connector and insert the cable as the solder
melts. Allow connector to cool and install the heat shrink. Attach this end to one ter-
minal on the 150 amp circuit breaker.
