STEERING SPRING RESISTANCE ADJUSTMENT
The MONOPOINT II system relies on a single spring pack of up to three springs.
The springs are designed to rest one inside another. Figure 24 shows the various
possible combinations of springs along with recommended preload settings.
To adjust overall steering resistance pressure, perform the following steps:
Loosen the locknut on the preload adjusting screw underneath the steering
unit, directly below the springs [Figure 21]. Turn the adjusting screw
counterclockwise until the spring pack is loosened.
Grasp the top of the spring pack and pull out from underneath the roller on
pressure arm. Remove the springs and spring retainers from the unit.
The tool and parts kit provided with the unit includes additional steering
springs. Select the desired combination of springs [Figure 21], and install
them on the lower spring retainer, making certain that they are seated in
their respective pockets. The default factory setting is 116lb.
Place the spring pack with the lower retainer over the preload adjustment
screw. Tilt the top of the spring set outward slightly to accept the upper
spring retainer, insert the retainer, and tilt the assembly back underneath
the roller on the pressure arm. Work the wheel from lock to lock to seat the
springs. IMPORTANT! Before setting preload, perform the following step:
If using the large outer spring, make sure to rotate the spring on the lower
spring seat counterclockwise until the lower end of the spring coil is seated
firmly against the set screw provided in the spring seat [Figure 22]. If the
spring is not seated against the set screw, the springs may make noise
during operation. If spring noise is encountered, this is the likely culprit.
Next set centering pressure in accordance with the following section.
STEERING CENTERING PRESSURE AT NEUTRAL
To adjust centering pressure at neutral position, refer to the preload settings in
Figure 24. This adjustment will not affect maximum resistance at full lock; it
should be used only to adjust feel characteristics through the very center of
travel. See Figure 25 for a graphic explanation of the effect of this adjustment.
Locate the preload adjusting screw [Figure 21]. Insert the supplied 3/16"
hex key wrench. With the steering wheel at center position, turn the preload
adjusting screw clockwise by hand (as viewed from the bottom) only until
there is no up/down looseness (gap) in the spring pack between the upper
and lower spring seats. Move the wheel back and forth to help determine
the point between loose and engaged.
Refer to the table [Figure 24] for the amount of preload desired. The preload
setting has a major effect on centering force around neutral. The lowest setting
will result in a very loose feeling through center with almost no centering force.
The maximum setting will result in a pronounced centering effect, especially with
heavier spring combinations. Figure 25 illustrates the effect this adjustment has
on overall resistance characteristics. Carefully to count the number of rotations of
the screw, turn only until the desired preload setting is reached.
