Link Rear Suspension...
Setting the Toe to Zero
Loosen the cap screws (A) (3 per side, unless equipped
with anti-tips then 4 per side) that secure the camber tube
clamp. Observe the ball in the level (B), and rotate the
camber tube (C) until the ball is centered in the level. The
toe is now set at zero (Fig. 4.7, 4.8).
Before tightening the screws (A), make certain that the
camber tube is centered left-to-right relative to the
wheelchair frame, and the flat portions underneath outer
camber tube clamp are parallel side to side. The end of
the camber tube should be flush with the outer most
portion of the camber tube clamp. Torque fasteners (A) to
62 in-lbs. (7 Nm).
Setting the Toe to Zero– Alternative Method
Place the entire wheelchair on a flat horizontal table or
ground surface. Loosen the cap screws (A) (3 per side,
unless equipped with anti-tips then 4 per side) that secure
the camber tube clamp. Locate the flat surfaces on the
front and rear of the camber plugs (D). Place an object
that is known to have an accurate 90° corner (such as a
carpenters square, drafting triangle, etc.) down on the flat
horizontal surface and up against the flat of the camber
plug.
Rotate the camber tube and plug assembly until the flat
surface of the camber plug is parallel to the measuring
tool (Fig 4.7, 4.8, 4.9, 4.10).
Before tightening the screws (A), make certain that the
camber tube is centered left-to-right relative to the
wheelchair frame and the flat portions underneath outer
camber tube clamp are parallel side to side. The end of
the camber tube should be flush with the outer most
portion of the camber tube clamp. Torque the fasteners to
62 in-lbs. (7 Nm).
CAUTION!
When turning the 4-Link Rear Suspension, always make
one change at time and write down the
change. This takes patience, but allows you to understand
how each change affects the ride of the
wheelchair in conjunction with rear suspension.
NOTE– The lower shock mount is designed to have a
loose feel, this is by design to allow for proper suspension
travel.
CAUTION!
Never remove the barrel nut (C) that connects camber
clamp to the shock camber clamp.
