Re-squaring Your Casters 25 | Sunrise Medical Quickie 2 Lite

2. Re-squaring Your Casters 25 26

Gently pry cap (A) off of both caster tubes. Locate the set screw (B) inside the right caster tube and loosen using an 1/4 inch hex key. Do not remove the set screw. Simply loosen it enough to allow the teeth on the upper and lower splines (C) to clear one another. With the stem bolt loosened, the caster fork should pivot freely. Place the wheelchair on the floor so that the two rear wheels and left caster con- tact the floor. Place some weight in the seat towards the rear to help stabilize the chair. Place a square or pocket level against the flat surface of the fork and pivot the fork until it is vertical (square) 24 . With the fork vertical, engage the teeth of the two splines to the closest mating position. Make certain that the teeth are properly engaged and not crossed. Shine a bright light behind the mating spline teeth and check for proper teeth engagement. Tighten the set screw (B) to secure the spline mating position. The set screw should be tightened to 192 in-lbs. (21.7 Nm) to ensure that it does not loosen during use.

Record the teeth engagement position of the splines on the right fork, and adjust the left fork in a similar fashion to the same position. Reassemble both casters, and re-check that they are square. Replace caps.
