LifeFitness Strength, Replacing a Roller Pad on a Leg Curl or Leg Extension

The LifeFitness strength leg curl and leg extension models all share a common roller pad design for the legs. The parts of this roller pad are the same across the models except for two parts; the screw and the cap. The screw is the same size diameter and thread, but the length varies based on the model of the leg curl. The cap color can vary between black and dark gray.

The parts related to the roller pad are called out with arrows in the image below. Starting with the cap at the outermost position of the pad, we will describe the parts of the roller pad.

The cap fits into the molded ring at the end of the roller pad to cover the end of the kicker and the hardware.

The screw threads into the end of the kicker and holds everything in place.

The plate is like a large washer. It fits between the screw and the spider nut.

The spider nut fits against the kicker and the screw threads through the spider nut into the kicker.

The roller pad. This is the cushion for your legs during the workout.

The shaft collar. The shaft collar is adjustable with a set screw. The collar works to hold the inner position of the pad on the kicker.

Replacing the roller pad is pretty simple. You will need a set of hex wrenches. The screw needs a hex wrench and if you need to make adjustments to the shaft collar, the set screw needs a hex wrench.
