Steering System Tension Adjustment
OPPOSITE SIDE ROUTED STEERING CABLES
IMPORTANT: After this Ride-Guide Attachment
Kit is installed, there must be proper tension in
the steering system. Not enough tension will
cause slack (play) in steering system. Too much
tension will cause steering cables to bind. Per-
form Step 1, following, to adjust for correct ten-
sion.
1. Loosen adjustment nuts and pull steering cable
mounting tube (by hand) away from end of steer-
ing cable (to remove slack in steering system).
Tighten adjustment nuts and check system for
slack (play) or too much tightness. If steering sys-
tem is too tight, readjust tube toward end of steer-
ing cable (Figure 10) or, if too much slack (play)
exists in system, readjust tube away from end of
steering cable (Figure 10). Tighten nuts and
readjust, if necessary.
