Onewheel GT Motor & Bearings Replacement

Written By: Justin Velasquez

Difficulty: Hard

Steps: 11 – 13

Time Required: 1 – 2 hours

Introduction

For your safety, power off your Onewheel GT prior to disassembly. This reduces the risk of electrical malfunctions and/or damage during the replacement process.

Note: Altering or damaging any component of your Onewheel GT during disassembly/reassembly may render your existing warranty void or lead to refusal of non-warranty service at the discretion of Future Motion, Inc. (the creators of Onewheel).

Step 1   Remove the fender/delete screws and fender/delete

  • Remove all four (4) screws using a TP25 bit.
  • Note: Keep screws organized as they are easy to mix up and/or lose.
  • To remove the fender/delete, apply pressure to each side of it, near the axle carriers, and pull it up and away from the Onewheel™.

Step 2   Remove the maghandle screw and maghandle

  • Remove the one (1) screw using a 3 mm hex bit.

Step 3   Remove the bottom front bumper screws and front bumper

  • Remove all four (4) screws using a TP25 bit.
  • To remove the front bumper, pull it toward the nose of the Onewheel™.

Step 4   Remove the bottom front footpad screws

  • Remove the two (2) screws using a TP25 bit.

Step 5   Remove the top front footpad screws and front footpad

  • Remove the two (2) screws using a TP25 bit.
  • Caution: For the front footpad sensor connector, turn (counter-clockwise) only the smaller part of the connector closest to the controller. Turning the entire body of the connector can damage it or your controller.
  • Note: If you are unable to remove the footpad sensor connector using your fingers, you may use a Future Motion™ footpad connector wrench or a pair of long nose pliers (be gentle).

Step 6   Disconnect the motor connector

  • Caution: For the motor connector, turn (counter-clockwise) only the smaller part of the connector closest to the controller. Turning the entire body of the connector can damage it or your controller.
  • Note: If you are unable to remove the motor connector using your fingers, you may use a pair of long nose pliers (be gentle).

Step 7   Remove the cable retainer screws and cable retainers

  • Remove all four (4) screws using a TP25 bit.

Step 8   Remove the hub bolts

  • Remove all four (4) bolts using a TP45 bit.

Step 9   Remove the hub/tire assembly

  • The hub and tire assembly can be removed by lifting it through the bottom of the rails (in order to clear the axle carriers).
  • Caution: Be careful not to damage the motor cable as you separate the hub from the rails. The cable must be gently manipulated in order to allow adequate clearance during removal.
  • Note: The axle carriers may come loose and fall out of the rails. This is not an issue. Set them aside for now.

Step 10   Remove the motor cover screws

  • Remove all seven (7) screws using a 4 mm hex bit.
  • Caution: DO NOT use power tools to remove the screws as they are easily broken.

Step 11   Remove the stator

  • Attach the motor cover side axle carrier to the axle with two (2) hub bolts using a TP45 bit.
  • Using a rubber mallet or arbor press, knock/press the side of the axle without the axle carrier into the hub (until it is nearly flush with the enclosed side of the hub).
  • To remove the stator, position the hub so that the side of the axle with the axle carrier faces upward. Placing your feet or knees on the tire, pull straight up on the axle carrier until the stator slides fully out.
  • Caution: Be extremely careful not to let the stator drop/pull back toward the hub as the magnets are very strong and can be damaged by the impact.

** If you need to remove your bearings, proceed to Step 12. **

Step 12   Remove the axle carrier and motor cover

  • Remove the two (2) bolts using a TP45 bit.
  • To remove the motor cover, pull it straight up on the axle; away from the stator.
  • Caution: Be extremely careful not to damage the stator PCB, hall sensors, or the motor cable while removing the motor cover.
  • Note: If you find it difficult to remove the motor cover from the axle, place the palms of your hands on the end of the axle with your fingertips curled under the edges of the motor cover; then squeeze.
  • Note: In the event that the motor cover comes off, but the bearing remains stuck on the axle, use a bearing puller to remove the stuck bearing.

Step 13   Remove the bearings

  • Remove the two (2) bearings using an arbor press and a 44.5 mm aluminum collar/disc.
  • Caution: Be extremely careful not to leave the hub magnets unprotected as they are very strong and can be damaged by an impact from the bearing.
  • Note: Inspect the two (2) axle o-rings after the bearings have been removed. If they appear damaged/stretched out, replace them.
