Slide the left spring onto the tube and add the cable drum. When your new springs arrive, put the new left spring (the 1 with the end facing up and to the left) on the torsion tube, making sure that the stationary cone on the end of the spring faces the center bracket. After sliding the new spring into place, replace the cable drum and insert the torsion bar into the left bearing bracket.
Keep in mind, the pulley is often cycled through an enclosed casing that is difficult to lubricate directly. By applying enough lubricant to the pulley, you’re ensuring that the whole lifting mechanism is properly lubricated. Furthermore, a jam in this portion of the lifting mechanism is a time-consuming and potentially labor expensive repair that requires a service professional.
