This guide explains how to remove and refit the bottom cover of Logitech G25, G27, G29, G920 and G923 pedals, giving you access to the pedal units, potentiometers and wiring loom.

There are other ways shown on the internet on how to do this. Trust us, this is the best way!

Tools required

Use Phillips (PH), rather than Pozidriv (PZ), screwdrivers. A hand screwdriver gives you better control and helps prevent overtightening.

• PH1 Phillips screwdriver — for the small screws.
• PH2 Phillips screwdriver — for the large screws.

If you also need to remove a complete pedal unit, you will need:

• Long-nose pliers.
• 2.5 mm hex key

Before you start

Disconnect the pedal cable from the steering wheel.

Take photos as you work, particularly of the wiring and its route through the housing. These will help you put everything back correctly.

The stock wires are thin and easily damaged. Never pull on the wires to disconnect them.

Removing the bottom cover

1. Support the pedals upside down

Turn the pedal assembly upside down and support the housing on a cardboard box or similar support. Make sure it is stable and the foot pads are not taking the weight.

2. Remove the two hidden screws

Move the retractable carpet gripper to expose the two small PH1 screws underneath it, then remove them.

These screws are easy to miss.

Keep all the screws somewhere safe!

3. Remove the remaining small screws

Remove the 12 small PH1 screws as shown in the photos. These fasten the plastic bottom cover to the plastic upper pedal housing.

Keep all the screws somewhere safe!

4. Remove the remaining screws

Remove the 12 large PH2 screws, as shown in the photos. These fasten the three pedal units to the bottom cover.

Keep all the screws somewhere safe!

5. Lift off the bottom cover

Carefully lift the plastic bottom cover away. If it does not come away easily, check for missed screws before trying again. Do not force it.

Identifying the pedal units

Each pedal unit usually has a handwritten factory marking underneath:

• A — Accelerator
• B — Brake
• C — Clutch

Use these markings to confirm which pedal you are working on. With the housing upside down, it is easy to confuse the accelerator and clutch.

5. Photograph the wiring

Before moving anything inside, take a clear photo showing how the wires are routed and secured around the plastic moulding. They must go back in the same positions to avoid being trapped during reassembly.

If you also need to remove a pedal unit

You do not need to remove the foot pads simply to take off the bottom cover. However, the foot pad must be removed before its pedal unit can be taken out of the housing.

Remove the two screws securing the foot pad using a 2.5 mm hex key, then remove the pad. Do this before turning the assembly upside down.

Remove the bottom cover as described above.

Photograph the wire connections so you can reconnect them correctly.

Remove the PH2 screw securing the black ground wire to the metal pedal chassis.

Use long-nose pliers to grip and carefully disconnect each spade connector from the potentiometer. Grip the connector itself, never pull or grip the wire.

Carefully lift the pedal unit out of the housing.

The black wire attached to the metal chassis is separate from the black connection on the potentiometer. Refit both connections when reassembling.

Refitting the bottom cover

Return any removed pedal units and reconnect their wiring. Check your photos to confirm that the wires follow their original routes.

Make sure no wires are trapped between the cover and housing, or positioned where moving parts could catch them. Place the bottom cover back into position without forcing it, then return each screw to its original location.

Protect the threads in the plastic

Many of the screws fasten directly into plastic. When refitting them, use the existing thread:

1. Place the screw in its hole and apply very light downward pressure.
2. Slowly turn it anticlockwise, as though loosening it.
3. Feel for a small click or drop as it finds the start of the existing thread.
4. Turn it clockwise to tighten.

If the screw feels difficult to turn, stop and try again rather than forcing it.

Tighten only until snug. Overtightening can strip the plastic thread.

Refit any removed foot pads, then check that all three pedals move freely before reconnecting the pedal cable to the wheel.
