How to Replace Truck Door Operator Balancer?
The Whiting door balancer, or Todco door balancer, is made up of a fixed shaft (it does not turn) and two spring assemblies with drums towards the walls for the cables to roll onto. Each spring thus absorbs half of the door’s weight.
In order to replace the spring balancer very well, you should proceed as follows:
1. Remove both cables from the door and install them onto cable drums. Make certain that the cable follows the grooves.
2. Install a cotter pin in the balancer shaft hole farthest from end. Remember to set the cotter pin properly. If not, it will interfere with drum rotation.
3. Install shaft into brackets. In the standard header, red end goes on roadside. In the shallow header, red end goes to the curbside.
4. Install and set cotter pin closest to end of the shaft.
5. Connect cables to door.
6. Wind balancer by inserting bar into winding cone and pulling down for standard installation, or by pushing up in a recessed header. Counting turns as soon as the cone rotates. 3 1/2 to 4 turns would be correct.
7. After the correct turns have been applied, insert the center clamp over the bracket and tighten both nuts securely.
8. Remove both clamps in the tracks carefully.
9. Lower the door and test it several times. A properly balanced door should not fly open, nor fall closed.
