Axle Clamp Mounting Instructions
NOTE: Refer to the separate directions provided for a folding frame
wheelchair.
Clamp Mounting
The SmartDrive adaptive axle clamp is designed to permanently
mount to the axle tube of a rigid wheelchair while presenting a
simple means of attaching/removing the drive unit.
First, verify that the proper clamp is being used based on the
wheelchair rear wheel size. This is noted on the front / back of
protrusions (Fig. A). Refer to the chart below for proper clamp
usage:
22" (501) Wheel / Tire
24" (540) Wheel / Tire
25" (559) Wheel / Tire
26" (590) Wheel / Tire
There are 2 different styles of clamps, standard tube [less than
1.4" (36 mm)] and large tube [greater than 1.5" (38 mm)]. Slide
the provided hard rubber inserts over the axle receiving tube to
accommodate smaller tube diameters (see chart below for sizing).
Dots on the side of the rubber inserts are used to identify the
tube size they fit:

CAUTION: The front and back of the
clamp will not mate even when the screws
are sufficiently tight. As shown in the
graphic below (Fig. B), there should be a
gap between the two parts. Over-tighten-
ing of the screws [more than 4 ft-lbs (5.4
N-m)] could cause the parts to break during
installation.
