What’s in the kit

Coreless digital servo
Brackets and hardware
130 lb braid (preferred over steel)
Servo horn that converts to a spool
Replacement accelerator lever (no side thumb)

Tools

10 mm (an extension is handy)
Phillips
Scissors
Optional: 4 mm socket to punch out the white/plastic clip

Why the accelerator lever is replaced

The OEM lever has a thumb that prevents actuating the throttle independent of the T-handle or remote. The kit lever removes that thumb so the servo can move throttle on its own.

Step 1: Replace the accelerator lever

Flip the white clip and drop the push rod.
Use a 4 mm socket on the backside of the white part to pop it out.
Save the OEM lever.
Install the kit lever.
Reinstall the push rod and clip.
Verify the throttle can move independently of the T-handle or remote.

Step 2: Mount the base bracket

The kit includes a bolt for the base bracket. Nudge the bracket angle so the servo can sit next to the flywheel plastic.

Step 3: Loop the braid on the throttle body

Loop the braid on the throttle body (any loop knot).
Run it under the tube and through the eyelet.

Step 4: Assemble the spool horn

Feed the braid inside-out through a hole in the round horn.
Tie a bulky knot.
Clip on the backing plate / spool adapter.
Wind the braid close, not super snug.
Press the horn onto the servo.
Install the black retaining screw.

Step 5: Leave tension for calibration

Do not finish tension now. Calibration is later, and you will pull the horn off again during TCM calibration. Continue with the TCM Installation Guide.
