1. Remove the calf protector to expose the lower end
of the knee angle tensioning device.

toward the front of the wheelchair to depress the
button on the black ratchet.
See figure 41.

.
4. Remove the pivot block and rubber bumper.
5. Use a 3/4-in. wrench to remove the nut from the
spring assembly.
6. Remove the spring and spring seat.
7. Change the spring.
8. Reinstall the spring seat. Install spacers, if desired.
9. Install the nut. The spring must be compressed
slightly to install the nut. Use a 3/4-in. wrench to
tighten the nut until it is flush with the end of the
tension tube.
10. Install the rubber bumper over the 0.25-in. (0.64-
cm) shaft.
11. Thread the pivot block onto the 0.25-in. (0.64-cm)
shaft. The pivot block does not have to be tight.
Make sure that the shaft does not protrude into the
0.25-in. (0.64-cm) hole for the bolt. Three to four
turns of the pivot block are ideal. Thread-locking
glue (such as Loctite) is NOT necessary since this
part cannot rotate once installed.
12. Install the bolt to connect the pivot block to the
lower leg rest rigging.
13. Repeat on other side, if needed.
14. Reinstall the calf protector to cover the lower pivot
point.
