4.
Tack-Weld Crossmembers: Once all areas that will be welded are prepped and cleaned, then the
cross member, chassis brace, and front supports can be tack welded into place. (Some grinding and
trimming may be necessary to provide proper fit up.)
Note:
Do not fully weld the crossmembers at
this time! Only weld enough to securely hold the parts in place during mock up. Hint: Weld in places
that can be easily accessed with a grinder in case it becomes necessary to move or adjust the parts.
5.
Assemble Truck Arms and Rear End Housing: Install the truck arms onto the front cross member
using the supplied 3/4"-16 X 5-1/2” cam bolts and spacers.
Note:
Install the cam bolts in the center
of adjustment as shown. The flat side of the bolt should be facing upwards. Tighten the nut until it just
touches the cam spacer, but do not fully tighten it yet.
Raise the rear end housing into its approximate location.
Using the supplied U-bolts and nuts, attach the
truck arms to the rear end housing. The U-bolts
only need to be snug at this time. There is no
need to fully tighten them yet. With the rear
end housing connected to the truck arms,
and raised up to ride height, you can now
tighten the cam bolts.
6.
Install the Watts Link Pivot: Once the truck arms have been connected to the rear end housing, it’s
time to mock up the watts link. Start by installing the center pivot to the rear end housing. Use the
supplied 3/4-16 x 3” bolt and washer to attach the pivot to the housing as shown. For initial mock up,
use the second hole from the top on the rear end housing.
