Replace Garage Door Torsion Springs

You are here: Home > Tutorials > Remove Your Torsion Springs

Warning: Torsion springs can cause serious injury or death if not handled

and installed properly. These instructions, winding rods, torsion drums,

and cables are for the purpose of replacing parts on residential type garage

doors that are no more than 18 ft wide and 8 ft tall, with inside lift and

springs mounted to the front header of the garage.

UNWINDING SPRINGS: Close door, disconnect the garage door opener and

install a "C" clamp or locking pliers on both sides of the track against the

top side of a roller to keep door from opening. Springs must be unwound

to relieve all stored tension before bottom rollers or bottom brackets can

be replaced. Do not work directly in front of spring winding cone of spring.

Place one of the winding rods in one of the four holes in the winding cone. (#1)

TIGHTENING SPRING: Do not work directly in front of spring or spring

winding cone (#1). Place a rod into one of the cone holes and lift up (#1).

WARNING: MAKE SURE RODS ARE ALWAYS FULLY ENGAGE HOLES

IN WINDING CONE.

Place second rod into the hole below, lift up and remove the first rod, continue

lifting the second rod. Repeat for the same number of turns noted when they were

unwound (about 29 quarter turns). While holding spring tension on rod (tension

can be held on the spring by putting a rod in the bottom hole of the spring cone

and relaxing other rod so the lower rod contacts the door and holds the pressure

of the spring against the top of the the door), tighten the setscrews in the spring

cone and remove the rods. Tension will be on the cables. Remove the locking

pliers (#9) from the shaft. If there is a second spring, repeat the process to wind

the second spring. After everything is completed and all bolts and screws tightened,

remove the "C" clamps holding the door closed and lift by hand to make sure door

is operating smoothly. Reconnect the garage door opener.
