This video shows an example on how to remove or replace the part on this type of machine, some models may be different but the procedure should be similar.

  What You Will Need:

  Step 1 - Safety Advice

Safety First! Please ensure that you have disconnected the battery from the Gtech before starting any repair.

  Step 2 - Removing Roller and Soleplate

With the battery safely removed you now need to remove the filters and dustbin assembly. Put that to one side because you now need to turn the Gtech over onto its front so that you can then remove the roller end caps and the rollers to access the soleplate.

This is pretty simple to do just remove the two screws that hold the end caps in place. It's worth pointing out that the rear screw for the end caps is longer than the front screw so remember that when reassembling your Gtech.

The roller end caps are easy enough to remove too, slide them up a little before popping them out - make sure you retain the brass bearing inside. The rollers are easy to remove as well, simply pull those off the central shaft.

  Step 3 - Detaching Front Assembly

Now that you have the rollers out of the way, the next thing you need to remove is this front assembly of the cleaner head. To do that you will need to undo two screws on both ends and one in the centre using a Torx's head screwdriver.

With the screws out, the front assembly will just fall out of place.

  Step 4 - Removing the Motor Assembly

With the two front pieces removed next thing you need to do is to remove the four screws which help to hold the motor assembly in place again using a Torx head screwdriver.

With the four screws removed from underneath the Gtech, you will now need to turn it over as there is still two screws on the inner side and two screws at the front holding the motor assembly in place, so unscrew those next.

With all the screws removed ease off the motor assembly front first just flexing the front to get it away. And then you should be able to lift the motor assembly up and out to access the gear assembly.

  Step 5 - Opening Up the Motor Assembly

Great work so far...now you need to undo the screws at the top of the motor assembly to take the casing off.

Next you can just pop off the ducting, put your fingers either side of the inlets, and that will simply pop off.

Now to remove the motor cowl which should hinge back. If you separate the two halves of plastic at the back and lift off at the same time it should just hinge out of place.

  Step 6 - Replacing the Brush Drive Gear

To access the gear assembly which is below the motor, you need to undo the five screws which hold it into place, again using the Torx head screwdriver.

With halve of the gear assembly cover taken off you’ll see the gear assembly inside.

Now to replace the gear…lift up the metal shaft to take out the nylon and metal gear assembly. Grab your new one and pop it into place. Simple!

  Step 7 - The Reassembly

Now let’s put it back together…with the gear assembly all in position you can now reassemble the cover; making sure it's all in place properly before screwing back together.

Next to replace the motor cowl hinging it into position, so make sure it’s in position at the bottom before easing the rest of the cowl over.

Now to get the ducting back into place… Just ease the motor cowl back a little bit to make sure it fits into position and then push the motor cowl back in place and then replace the centre screw - followed by rescrewing the unit to the machine.

To replace the brush head and soleplate assembly just drop the soleplate into position first and then put the top cover over and rescrew it into place.

With the cover in place now you can replace the brush rolls but making sure that the two flat sides of the fitting match up to two flat sides on your drive shaft. Finally screw back on the end caps and drop in the filters, dustbin and battery.

There you have it! It was a slightly lengthy process but we got there together, so you should be proud of yourself. We hope that this has helped provide you with an easy to follow guide on how to replace a faulty or damaged brush drive gear for your vacuum.
