NOTE:
Figure 22-1.
Note that the pivot assembly pivot point (B) is one
point of a triangle. The other two points (A & C) are on top of the truck.
The two downwards-pointing legs of the triangle must be the same length.
These steps will make sure that the two legs are equal. The D dimension
indicates the amount of offset from the center of the pivot mounting hole
to the center of the pivot point. This will change with the different size of
pivots. See chart for offset dimension.
1)
Mark the rear edge of the tarp housing or the mounting plate in line
with the tarp roll up bar on the driver’s side and passenger’s side. Mark
these points and call them (A).
2)
Determine where you want the rear of the tarp to be when it fully
covers the box. Mark these points and call them (C).
3) Figure 22-1.
Find a point at the side of the box that is the same
distance from A and C. This is point B, where the spring assembly will
be mounted. Mark this point on both sides.
NOTE:
The mounting brackets should be bolted to the dump body; if the
trailer/truck body has an enclosed floor, then the mounting brackets can
be welded in place.
4)
Position the driver’s side mounting bracket (1) to the point marked on
the driver’s side (B). Note the (D) offset dimension for your pivot size.
Clamp the mounting bracket into position. The top of the mounting
plate should be as high as possible from the bottom of the box.
5) Figure 22-2.
Drill three 17/32" holes.
6)
Bolt the pivot mount to the box or rail with 1/2-13 x 4 hex bolts (2),
1/2 flat washers (3), and 1/2-13 nylon hex nut (4).
7)
Repeat
Steps 5a.4–5a.6
for passenger’s side, then continue to page 24.
See note on page
21 for Pivot Mount
drilling requirements.
