How to replace the drive belt in your food processor

Gemeinsam reparieren - Jetzt registrieren

Einleitung

If the motor runs but the blade stays still, the drive belt is probably broken, stretched, or has slipped off its pulleys. Replacing or retensioning the belt and adding fresh lubrication to the motor bushing and gearbox restores full power and protects the gears from wear. Perform this repair whenever you notice slipping, squealing, or dry running noises.

Was du brauchst

Schritt 1 Disconnect power and clear the work area

Unplug the food processor from the wall outlet.
Remove the bowl, blades, and any other accessories.
Set the loose parts aside to prevent damage or loss.

Schritt 2 Expose the cover screws

Insert a flat screwdriver under a rubber foot on the base.
Lever the foot out to reveal the hidden screw below.
Repeat for every foot that hides a screw hole.
Select screwdrivers that match the actual screw heads used on your model.

Schritt 3 Remove the bottom cover

Unscrew all exposed screws and set them aside safely.
Lift the bottom cover off the housing to access the drive area.
Keep the screws and feet together so nothing is misplaced during reassembly.

Schritt 4 Inspect the original belt

Check whether the belt is torn, overstretched, or merely slipped off a pulley.
Heavy dough loads can push a healthy belt off its pulleys without tearing it.

Schritt 5 Select a matching replacement belt

Take the old belt to a shop that specializes in belts to obtain an identical replacement.
Match the new belt by overall length, tooth pitch, and tooth thickness.
Use the printed markings on the old belt to help the vendor supply the correct type.

Schritt 6 Loosen the motor mount for tension adjustment

Locate the four screws that secure the motor to its mounting plate.
Loosen each screw just enough for the motor to slide on its slots.
Support the motor so its weight does not strain the loose screws.

Schritt 7 Lubricate the motor bushing

Add a few drops of machine oil to the lower motor shaft bushing.
Keep oil away from the pulley teeth to avoid belt slippage.

Schritt 8 Install the belt and set correct tension

Loop the belt over the large drive pulley first.
Slip the belt onto the motor pulley.
Pull the motor away until the belt deflects about 3 to 5 mm under firm thumb pressure.
Hold the motor in position and tighten two opposite mount screws.
Re-check belt flex, then tighten the remaining mount screws fully.

Schritt 9 Reassemble the base

Place the bottom cover back onto the housing.
Insert and tighten all cover screws securely.
Press the cleaned rubber feet back into their recesses until flush.

Schritt 10 Test basic operation

Reconnect power and run the motor briefly with no load to verify smooth, quiet operation.
Confirm that the belt stays centred on the pulleys without walking off.
Unplug the appliance before continuing to further work.

Schritt 11 Open the gearbox cover on gear-drive models

Remove the single screw securing the upper gearbox cover.
Lift the cover carefully, protecting any scale or sensor wiring inside.
Undo the three small screws that hold the gearbox plate in place.

Schritt 12 Grease the gearbox bushing and gears

Lift the gearbox plate along with its bushing and washers.
Spread industrial grease on the metal bushing and plastic gear teeth while rotating the gear by hand.
Apply grease to the shaft and the bushing inside the cover.
Use grease formulated for plastic gears to prevent chemical damage.

Schritt 13 Reassemble the gearbox

Return the washers to their original order on the shaft.
Seat the gearbox plate and insert all three screws finger-tight.
Tighten the screws in an alternating pattern so the plate sits evenly.
Re-fit the outer cover and secure its screw.

Schritt 14 Use photos for reference

Photograph each disassembly stage to help identify screw positions during reassembly.

Abschluss

A correctly tensioned belt and fresh lubrication can bring even decades-old food processors back to full performance. Repeat lubrication and belt checks whenever the machine starts to slip or sound dry to keep it working like the first day.
