B&D Panelift B&D Storm-Shield PFI Installation Instructions Manual - page 25
For very large doors whose springs simply become too large
and heavy to handle in a complete single axle assembly, two
solid torsion axles are supplied with a coupling to allow easier
installation.
Assemble both axle assemblies on the floor, only one Spring
Anchor bracket is used, the other Spring Anchor bracket is
fixed in position at the wall. Figure 48 shows the right half
of the axle assembly as it should look on the floor. The shaft
collar should be butted up against the Spring Anchor bracket
opposite of the spring and then firmly fixed into place.
Lift and thread the Axle on the Cable Drum side through the
mounted Spring Anchor bracket and fix the loose Spring
Anchor bracket securely to the lintel, you may need to rest the
assembly end on the ladder or scissors lift.
Assemble the Torsion Shaft Couple engaging both left and
right hand axle assemblies as shown in Figure 49, it will
not be necessary to tighten the bolts as yet, allowing some
adjustment. The axles should be flush with each couple
allowing free rotation to occur.
Secure the springs assemblies to the Spring Anchor brackets
as shown in Figure 50. The complete assembly should look like
Figure 51 by this stage. Cut the key to the required lengths and
then insert into the slots as shown in Figure 52 for the couple.
Attach lifting cable to cable drum in the same fashion
described on page 23 and adjust as described, however a key
needs to be inserted into place as shown in Figure 53 when
tightening the grub screws, the couple should allow some
adjustment before tightening the bolts connecting the two
axles fully.
The springs are tensioned in the same fashion as described on
page 28, however with the additional step of insertion of keys
into the slots which should be lined up between the winding
drum and axle then fixed firmly in place with grub screws,
Figure 54.

Check the orientation of the bearings in
Spring Anchor Brackets. The Flange side
must be on the same side as the Shaft
Collar, Figure 50.
The bearing can be ‘popped’ out and
reversed, if this is not the case.
