1. Use the side lever to tilt the steering column fully down.2. Use the floor pedal to tilt the steering column ½ backwards.
3. Telescope the steering wheel fully out and lock the steering wheel in place:
a. Turn center knob counter clockwise.
b. Pull up on steering wheel.
c. Lock wheel position.
d. Turn center knob clockwise.
4. To remove the seven screws from the top plastic housing, use a #1 Phillips screwdriver.
5. Remove the upper housing.
6. Use the side lever to tilt the steering column fully up.
7. Remove the right side switch block.

Tip: Ensure the bottom of the housing hinges down and under the steering wheel tilt lever.
9. Push the turn signal indicator out of the lower plastic housing.
10. Remove the connector from the turn sign indicator.
11. Slip the connector back through the square hole in the housing. Remove the housing completely from the column.
Step 2: Modifying the steering column housing
Cut down both the upper and lower plastic cover by four inches.Note: Use the same steps to modify the upper cover (not shown).
1. Use a black permanent marker to mark the cut location at the inside bottom rib.
2. Use a Dremel rotary tool and #561 cutting bit to cut the plastic. Set the Dremel tool for 600 RPM and then cut slowly.
3. Use a Dremel rotary tool and 470 sanding band to smooth the cut edge.
Upper and lower cover (outside and inside view) with four inches removed.

Step 4: Installing the EZ-Steer platform kit
1. Use the right side tilt lever to tilt the steering wheel ½ up.
2. Use the floor pedal to tilt the steering column fully up.
3. Use the 5/16 inch carriage bolts and nylock nuts included with the platform kit to assemble the 53059-05 bracket on the exposed metal column.
Note: The top and bottom carriage bolts are installed opposite each other. The top bolt is installed left-to-right. The bottom bolt is installed right-to-left.
a. Squeeze the bracket clamps together by hand.
b. Use a 9/16 gear ratchet combination wrench to turn the nylock nuts down against the clamp.
c. Rotate the slotted arm to a 1:30-2:00 o’clock position.
d. Tighten each nut to a maximum torque of 6.8 Nm (5 ft-lbs).
Note: The slotted arm should not block the hazard lights toggle switch, which is located under the bracket on the right side.
4. Loosen the steering wheel and telescope it downward until there is 23 cm (9.5 inches) distance between the slotted arm and the center of the steering wheel ring.
Step 5: Installing the EZ-Steer motor

a. Loosen the wing nuts.
b. Slide the motor inward or outward until the distance is set.
c. Retighten the wing nuts.
5. Pull the motor knob outward. The motor will spring against the steering wheel.
6. Tilt the steering wheel fully down.
7. Check the drive wheel alignment with the steering wheel ring.
a. Put the vehicle in park.
