Logitech G27 Internal Motors Replacement

Difficulty

Steps

Time Required

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.

Tools

Step 1

Remove the six gray 25mm hex screws with a 4mm allen wrench.
Watch out when you lift the wheel up, as there are fragile wires connected to the bottom side.
Carefully lift up the wheel, but do not disconnect it from the rest of the device.

Step 2

Carefully lift the wheel off of the hub, exposing the 2 shifter paddle wires and PCB board.

Step 3

Remove the two 7.5 mm silver screws holding the green PCB board in the wheel with a Phillips #1 screwdriver.

Step 4

Carefully remove the PCB board from the wheel hub.

Step 5

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.

@alexdinpoik I’ve had the same problem when the 7 pin connectors blue and green cables broke off. First, only the blue one was broken which only took the led indicators gradual increase but all buttons were working then when i tried to plug in back, the green one broke off leading to none of the buttons working but the led indicators just working. Now i’ll try to fix it with iron soldering.

okan can u pls share a video of you doing it? so i can do the “copy paste” hahah where can i buy cables and stuff i need for that? whats the name of these white connectors ? im new to this but share me a link to buy. i rather just try to fix it then buy a new wheel since its a great wheel compare to g29 that has bad software and the other wheels are to expensive. g27 cant be found in stores anymore neither and if im gonna buy one it has to be new haha hopefully u can share some knowlage thanks!

Step 6

You can now fully remove the wheel from the hub. Set it aside until you put the wheel back together.
Remove the innermost three 37.5mm silver screws with a Phillips #2 screwdriver.
Remove the wheel hub and push the connector through the center of the hub.

Step 7

The wheel hub can now be set aside and flip over the steering wheel housing to reveal the under side.
Remove the eight 15.9mm silver surrounding screws underneath the wheel housing with a Phillips #1 screwdriver.

Step 8

Rotate the housing back over and remove the top half of the housing revealing the majority of the components of the wheel.
The housing cover can be set aside until you put the wheel back together.

need two new black screes abouve the pcb board.. lost them need to know the size since the screws i replace it with was not exact..

Loosen the desk clamps before removing the housing, otherwise you risk breaking something. The housing should come off without having to use any force whatsoever.

Step 9

Remove the four 7.3mm silver screws attaching the green PCB board to the motor housing with a Phillips #2 screwdriver.

I’d do steps 9 and 10 in reverse order, the connectors are much easier to unplug while the board is secured in place.

Step 10

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.

I didn't take them off :)

I messed up and broke the cables of the 5 Pin Connector on the right. Can anyone tell me what it’s called so I can buy replacement? The Rest of the cable is stuck in there so I can’t re-use it sadly.

Step 11

Remove the PCB board after all of the plastic connectors are disconnected.
You can now set it aside.

Step 12

Remove the two 12.3mm upper black screws with a Phillips #2 screwdriver.
Remove the two 15.5mm bottom silver screws with a Phillips #1 screwdriver.

Step 13

Remove the PCB board mount and remove the clear plastic piece underneath.
Set them aside until you reassemble the wheel.

Step 14

Remove the four 12.2mm screws using the Phillips screw driver.
The motors and gear box should now slide out. As you take it out, the metal spring band as well as the track for the wheel gear will also slide off.
During reinstallation, make sure when doing this step to align the stop on the wheel gear with the track as shown in the second and third pictures.
When you have separated these parts, you can set them aside until reassembly.

Step 15

Next remove the eight 15.8mm screws that connect the plate holding the motors to the gear box.
When separating the gear box from the motor plate and motors be sure the gears do not fall out as they are difficult to put back in.

Step 16

Remove the six 7.4mm screws that attach the motors to the motor plate and slide the motors off the motor plate.
The motor plate can be set aside and the motors can now be replaced.
