Wayne-Dalton 346918 Center Bracket Bushing Assembly, Torsion Spring Attachment, Tools Step Ladder

the end bearing bracket’s upper or lower slots to the left hand horizontal track angle using (2) 3/8”-16 x 3/4” truss head bolts and (2) 3/8”-16 nuts.

IMPORTANT: The end bearing bracket’s lower slots are used on doors with 12” radius track; the upper slots are used on doors with 15” radius track.

Secure the top of the end bearing bracket to the jamb with (1) 5/16” x 1-5/8” lag screw. Repeat for other side.

20	Center Bracket Bushing Assembly
	Tools: Step ladder, Power drill, 7/16” Socket driver, 1/4” Torx bit, Level,
	Tape measure, Pencil

Locate the center of the door. Mark a vertical pencil line on the mounting surface above the door, at the center. Measure from the center of the bearing, in one of the end bearing brackets, downwards, to the top the door. Using that measurement, measure that distance upwards from the top of the door to the mounting surface and mark a horizontal pencil line which intersects the vertical pencil line. Align the edge of the center bracket with the vertical pencil line and the center of the center bracket with the horizontal pencil line; this is to ensure the torsion shaft is level between the center and end bearing brackets.

Attach the center bracket to the mounting surface, using (2) 5/16” x 1-5/8” lag screws and

(1) 5/16” x 2” tamper-resistant lag screw.

IMPORTANT: Use a 5/16” x 1-5/8” tamper-resistant lag screw instead of the 5/16” x 2” tamper-resistant lag screw if mounting surface is mounted over masonry. Tamper-resistant lag screw must be attached through the bottom hole of the center bearing bracket.

21	Torsion Spring Assembly
	Tools: Step Ladder

IMPORTANT: Right and left hand is always determined from inside the building looking out.

NOTE: Identify the torsion springs provided as either right hand wound (red winding cone), which goes on the LEFT HAND SIDE or left hand wound (black winding cone), which goes on the RIGHT HAND SIDE.

Facing the inside of the door, lay the torsion shaft on the floor. Lay the torsion spring with the black winding cone and the black cable drum at the right end of the torsion shaft. Lay the torsion spring with the red winding cone and the red cable drum at the left end of the torsion shaft.

NOTE: The set screws used on all torsion winding cones and cable drums are now colored red. DO NOT identify right and left hand by the set screw color.

Slide the center bracket bushing onto the torsion shaft followed by the torsion springs and cable drums.

IMPORTANT: The center bracket bushing, torsion springs, and cable drums must be positioned, as shown.

With assistance, pick up the torsion spring assembly and slide one end of the torsion shaft through one end bearing bracket. Lay the middle of the torsion shaft into the center bracket. Slide the other end of the torsion shaft into the other end bearing bracket. Position the torsion shaft so that equal amounts of the shaft extend from each end bearing brackets.

22	Torsion Spring Attachment
	Tools: Step Ladder, Ratchet Wrench, 9/16” Socket, 9/16” Wrench

Slide the center bracket bushing into the center bracket. Align the stationary spring cone(s) with the holes in the center bracket bushing assembly. Secure the torsion spring(s) to the center bracket bushing assembly with (2) 3/8”-16 x 1-1/2” hex head bolts and (2) 3/8”-16 nuts.

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.
