The Lower Key(15) needs to be adjusted first. This key must align with the Steering
Post. When the Steering Post is "Straight" you should be able to shift into steer mode smoothly. To adjust
this key, loosen the 4 screws underneath the dolly that hold the Lower Key assembly in place. The key assembly
can rotate slightly to the left and right. Move it to make a smooth shift into Steer Mode, then tighten the 4 screws
The Upper Key(12) keeps the Upper Sprocket Assembly(2) locked in place when in
crab mode. In order to have smooth shifting between crab and steer modes, the Upper Key(12) must be aligned properly
with the Lower Key (15).
To adjust the Upper Key, loosen the two Upper Key Plate Screws(17) in Figure S7. Align the Upper Key Plate (18)
so that shifting between crab and steer modes is smooth and straight, then tighten the two screws.
The Shifting Rod is located inside the Steering Post. See Figure S8. It must
be set to the proper length to fully engage the Center Key(14) when shifting between crab and steer modes. If this
is not correct, you may feel a 'bump' when turning the Steering Post past the straight position.
In Steer mode, the Upper Engagement Bracket(13) must be touching the Center Key Body(16) as shown in Figure S6.
If there is a gap, the Shifting Rod must be lengthened. In crab mode, the Lower Engagement Bracket(19) must be
touching the Center Key Body(16) as shown in Figure S7. If there is a gap, the Shifting Rod must be shortened.
To adjust the Shifting Rod, see Figures S8 and S9
To make the adjustment, remove the Push
Bar/Steering Post from the dolly.
Locate the set screw on the Lock Nut through the Access Hole(20) near the end
of the steering shaft. Loosen the set screw with a 5/64" hex wrench (some
models use a 1/16" wrench). Next, place a flat screwdriver into
the end of the Steering Post(22) and wedge it in beside the Lock Nut on the Shifting Rod to prevent the nut from
turning, as shown. Then turn the Shifting Rod Knob(24) clockwise to shorten the Shifting Rod, or counter-clockwise
to lengthen it. (One full turn is 1/18th of an inch.) The amount you need to adjust depends on the gap as described above for figures S6 and
