IF YOU HAVE A TORSION SHAFT OR A TORSION KEYED SHAFT:
With assistance, pick up
the torsion spring assembly and slide one end of the shaft through the rear support bracket.
Extend the shaft through the bearing until the opposite end of the shaft can be inserted into
the other rear support bracket. If your door came with oval bearing(s), loosely attach the oval
bearing to the center bracket with (2) 3/8” - 16 x 1-1/2” hex head bolts and (2) 3/8” - 16
hex nuts, as shown. Repeat for others, if needed.

IMPORTANT:
THE SPRING WARNING TAG(S) SUPPLIED MUST BE SECURELY ATTACHED
TO THE STATIONARY SPRING CONE(S) IN PLAIN VIEW. SHOULD A REPLACEMENT SPRING
WARNING TAG BE REQUIRED, CONTACT WAYNE DALTON FOR FREE REPLACEMENTS.
FOR DOORS WITHOUT COUPLER ASSEMBLY:
Equalize the amount that the torsion shaft /
torsion keyed shaft protrudes on each side. Align the stationary cone(s) of the torsion springs
with the slots in the rear support bracket and secure using (2) 3/8” - 16 x 1-1/2” truss head
bolts and (2) 3/8” - 16 hex nuts.
FOR DOORS WITH A COUPLER ASSEMBLY:
At the middle of the two center bearing
brackets, re-assemble the coupler assembly by loosely fastening the coupler halves together
re-using the (3) 3/8” - 16 x 1-1/2” hex head screws, (6) 3/8” Washers, (3) 3/8” lock washers
and the (3) 3/8” - 16 hex nuts, as shown.
NOTE:
Ensure both torsion keyed shafts have equal amounts of the shafts extending from
each rear support bracket.
Next, align the stationary cone(s) of the torsion springs with the slots in the rear support
brackets and secure using (2) 3/8” - 16 x 1-1/2” truss head bolts and (2) 3/8” - 16 hex nuts.
Repeat for opposite side. Secure all oval bearing(s), to the center bracket with (2) 3/8” - 16 x
1-1/2” hex head bolts and (2) 3/8” - 16 hex nuts.
NOTE:
If you have 4 springs, secure the torsion spring(s) to the center bracket with (2) 3/8” -
16 x 1-1/2” hex head bolts and (2) 3/8” - 16 nuts.
IMPORTANT:
NEVER USE MORE THAN ONE BEARING WHEN ATTACHING TWO SPRINGS TO
ONE CENTER BRACKET.
