Introduction

This guide will pick up from the pre requisite guide Disassembling Logitech G27 Steering Wheel. In this guide we will be showing how to replace the motors that create force feedback in-game. After following this guide your Logitech G27 Steering Wheel should be fully functional.

Image 1/1: Be careful when unplugging this adapter, try not to pull on the wires to avoid damaging them. Instead, wiggle around the plastic connector while pulling on it to loosen it.
  • Carefully pinch and unplug the large 7-pin connector under the PCB board.

  • Be careful when unplugging this adapter, try not to pull on the wires to avoid damaging them. Instead, wiggle around the plastic connector while pulling on it to loosen it.

These screws refused to go all the way back in for me, and one of them stripped completely. If this happens to you, you can get replacement screws that are shorter here - https://www.amazon.com/gp/product/B01MFA...

This works for the G27, not sure about the G25 or any other wheels.

Obviously the screws being shorter means the wheel isn't as strongly attached to the base in this direction, so if you have to do this remember not to put unnecessary stress on these screws by pulling the wheel straight off the base.

Image 1/1: Unplug the two plastic connectors on the top of the PCB board.
  • Unplug the three plastic connectors on the left side of the PCB board.

  • Unplug the two plastic connectors on the top of the PCB board.

  • Unplug the three plastic connectors on the right side of the PCB board.

  • Pulling the plastic connectors requires a lot of force, but be careful and don't pull directly on the wires. Try to wedge or push the male side of the connector out.

  • If you need some extra leverage when removing these connectors, try using a plastic opening tool to pry off the connectors.

  • Removing these connectors allows easier access to the four screws attaching the PCB board mount to the motor housing.

Some of the connectors have locks on them, I would recommend this as a two person job.
