Step by Step Guide: How to Replace Preethi Mixer Grinder Motor Coupler

Replacing the motor coupler on your mixer grinder is a relatively easy task that can be done in a few minutes. Here are the steps:

Step 1: Unplug the Mixer Grinder.

Before you do anything, make sure that the mixer grinder is unplugged from the power outlet. This is to prevent any accidents from happening while you’re working on the appliance. If you mixer grinder is cordless, make sure that the batteries are removed. Make sure the mixer grinder is completely turned off before proceeding.

Step 2: Remove the Body of the Mixer Grinder.

Using a Phillips head screwdriver, remove the screws that hold the body of the mixer grinder together. There should be four screws in total. Once the screws are removed, lift off the top half of the mixer grinder body to reveal the internals of the appliance. Make sure that, the mixer grinder is unplugged, before removing the body so that you don’t accidentally cut yourself on the blades.

Step 3: Remove the Mixer Grinder Blades.

Locate the blades of the mixer grinder. There should be three of them- a large one in the middle and two smaller ones on either side. Using a flathead screwdriver, loosen the screws that hold the blades in place. Once the screws are loosened, carefully remove the blades from the mixer grinder. Be careful not to cut yourself on the blades as they are sharp.

Step 4: Locate the Motor Coupler.

The motor coupler is a small, circular piece of plastic with metal teeth on the inside. It is located on the shaft of the mixer grinder motor. If you can’t see it, it might be hidden by the mixer grinder housing. In that case, you will need to remove the housing to access the motor coupler. Make sure that, the mixer grinder is unplugged, before removing the housing so that you don’t accidentally cut yourself on the blades.

Step 5: Disconnect the Motor Wires.

There are two wires that connect the motor to the power source. Using a flathead screwdriver, carefully disconnect these wires from the terminals on the motor. Be sure to remember which wire goes where, as you will need to reconnect them in the same order when you replace the motor coupler.

Step 6: Remove the Old Motor Coupler.

Using a flathead screwdriver, carefully remove the old motor coupler from the shaft of the mixer grinder motor. Be careful not to damage the shaft as you remove the old coupler. If there is any residue left on the shaft from the old coupler, you can remove it with a rag.

Step 7: Install the New Motor Coupler.

Carefully install the new motor coupler onto the shaft of the mixer grinder motor. Make sure that it is securely in place so that it doesn’t come loose while the mixer grinder is in use. If you see any residue on the shaft, you can remove it with a rag.

Step 8: Reconnect the Motor Wires.

Reconnect the two wires to the terminals on the motor, making sure that they are in the correct order. Again, be careful not to damage the wires as you connect them. Also, check if the new coupler is firmly in place before reconnecting the power and turning on the mixer grinder.

Step 9: Install the Mixer Grinder Blades.

Carefully install the mixer grinder blades, making sure that they are in the correct order. Be careful not to cut yourself on the blades as you handle them. Once the blades are in place, tighten the screws that hold them in place.

Step 10: Test You Mixer Grinder.

Once you have finished all the steps, plug in your mixer grinder and turn it on to test if it is working properly. If everything is working correctly, you can now reassemble the body of the mixer grinder. Make sure that all the screws are tightened properly so that the body doesn’t come apart while you’re using the mixer grinder.

That’s it – you have successfully replaced the motor coupler on your Preethi mixer grinder. Do not use force while grinding or juicing, as this might cause damage to the newly installed part. Also make sure to keep the mixer grinder unplugged when not in use, to prevent any accidents. With proper care and maintenance, your mixer grinder should last you for many years to come.
