If you have deducted that the motor is continuing to operate but the blade no longer turns you can diagnose that the fault is lying with the belt. Regardless of it being snapped or perished this is a crucial component to your lawnmower and imperative to fix the fault as soon as possible.
In this article we show you how to replace the belt on a Flymo Turbo Compact 330 however it is worth noting that the process should be very similar for other variations of Flymo which share the similar appearance.
The process shouldn't take too long and will save you money as repairing the fault yourself will save you from shipping the machine to an expensive repair centre for a simple repair.
This video shows an example on how to remove or replace the part on a typical 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 appliance from the mains before starting any repair and due to the sharp edges exposed we suggest suitable Safety Gloves are worn to help prevent injury.
Step 2 - Stripping the Mower
Before we can get to the belt we first need to remove the collection box along with the handle - it is worth noting that the handle doesn't need to be removed, however it will make the process a little more easier.
To remove the handle you simply need to remove the little metal clip and pin which hold it in place, with them removed on both sides you can pull the handle away.
After removing the collection box you can unscrew the motor cover, it will be held in place by two screws.
Step 3 - The Blade the Spacer and the Impeller
With access to the motor you need to unclip the two spade connectors - there is no need to worry about remembering their original location as it does not matter. Also remove the two foam filters which are on either side of the motor.
You can now flip the lawnmower upside down giving you access to the blade, impeller and spacers, these can all be removed. Using the flymo spanner which will have come with your lawnmower - you can release the nut hold it all in place.
With the impeller, blade and spacers removed you will now see the underside of the motor and drive assembly which needs removing.
Step 4 - Releasing the Motor
You will notice that the motor and drive assembly is being held in place by eight torx head screws - therefore using a torx head screwdriver bit you can remove the screws.
However before removing the final screw take a hold of the motor as otherwise it’ll drop and could possibly become damaged. With the last screw removed you can gently rest the motor and drive assembly down.
Step 5 - Giving Some Slack
With the mower turned over again you’ll now be able to see the motor, drive assembly and belt. Of course if your existing belt has been damaged it won’t be in place, however if it has only frayed and perished then we will have to remove it - and here is the best practice.
You will see four screws holding the motor in place on the drive assembly, well these can be loosened (do not remove them completely) upon relieving the pressure the belt will be slacked meaning we can simply slip it off.
Step 6 - Applying the Pressure
With the belt removed we can now fit the new one, first of all fit the belt in place. We need to tighten the belt like it was before we loosened the motor. With the belt on, push away the motor away from the drive assembly and this will tighten the belt. With the belt tight begin to re-screw and tighten the screws on the motor - once they are done give the belt a turn to check that it rotates smoothly.
Well done so far - we are almost done, we simply need to re-assemble the mower.
Step 7 - Reassembly
You want to start by flipping the machine over and rescrewing those eight torx screws which will hold the motor and drive assembly in place. You can then refit the impeller, the spacers and blade...ensure you face the blade the correct way; the blade should state which side should face the grass.
With the motor and drive secure, the impeller, blade and spacers in position you can once again flip the machine over from here you need to reconnect the spade wires, fit the foam filters and re attach the motor cover in place.
Simply fit the grass box and install the handles onto the lawnmower and you’re all done.
