To install the magnets (part A in
figure 1) on the drive shaft, use
the Epoxy (B). Spare magnets are
provided in the Hardware Kit (E)
should they be needed.
(For
front wheel drive
vehicles,
the magnetic targets should be
attached to the inner CV joint, on
the larger section between the rubber boot and the transmission.)
Note that the epoxy provided needs 6-8 hours to cure properly before the
vehicle should be driven. The magnets can come loose and be lost if the
vehicle is driven before the epoxy has a chance to cure. A quicker setting
epoxy can be used if you need to cut down on curing time. Also, the zip ties
(C) can be used to tie the magnets in place after the epoxy dries to make
sure they stay in place.
Mount the first magnet with the SOUTH pole side (dashed line) facing
toward the hub or shaft. Mount the second magnet with the NORTH pole
side facing toward the hub or shaft, as shown in Figure 2-14. A test magnet
should be used after installation to ensure the magnets have been placed
correctly. Pass the test magnet over the installed magnets and it should
alternately attract and repel.
For proper operation, the North
and South magnet sets must be
evenly spaced around the wheel
or drive shaft, at least 1” apart,
as shown in Figure 2-15. Spacing
from one North-South magnet set
to the next set is not as critical, but
should be uniform.
