BOTTOM HANGERS:
Find the Low Lift bottom Hangers, the cables,
Clevis pins, Humpback Spring pins, and washers. Assemble Low Lift
bottom Hangers as shown in Figure 55 A. Then assemble onto the
bottom panel as shown in Figure 55 b.
CURVE ASSEMBLY:
Insert plastic curve onto the inside of the top
brackets and secure onto bracket using 2 nuts and bolts per curve
insuring that the “v” of the vertical track lines up with the curve.
From the Rear Torsion parts bag assemble each pulley wheel with the
spacers sandwiched between opposite handed corner brackets and
held with a nut, bolt and washer as shown in Figure 60. The two corner
brackets should overlap and be secured into place. Secure against the
wall in 3 points and connect to vertical tracks at two points as shown.
AxLE ASSEMBLY:
The axle assembly for rear torsion is different in
that the Side bearing brackets are replaced with Sheave bracket Rear
Torsion off which the springs are mounted and which are connected
to the free ends of the horizontal tracks rather than directly over the
opening.
Figure 57 illustrates the assembly of single spring rear torsion
installation. A shaft Collar is still required and fixed on the spring side
of the Flat Spring Anchor brackets as shown in Figure 56.
Figure 58 demonstrates a double spring rear torsion installation, which
like a single spring rear torsion door has the springs mounted off the
sides on the Flat Spring Anchor brackets rather than the centre.
For both variations the cable drums are mounted on the outside of the track and brackets with the grub screws pointing away from
the centre as shown in Figure 59 Additionally the red and black springs are put on opposite sides of the axle than for a standard
installation.
