How can you repair a damaged blender?

Dear steemians a greeting.

Today I want to show you a new post about the field of repairs, to which I have been dedicated for more than 6 years. In this publication I will show you how I repair a blender, applying my knowledge in the field.

In today's case, we have an Oster blender from a customer who is unable to blend the food. When I looked at the product, I could see that there was wear between the parts that fit together. These parts are the motor quadrant and the gear knurl of the blade (the gear knurl is not replaced, the assembled blade is replaced).

Coupling wear is a very common fault in Oster blenders. Normally the motor quadrant is changed twice a year when the product is overused and for less overuse once a year. In the case of the blade it needs to be changed at least twice a year when the use is excessive.

It is very difficult for many people to fit the coupler, but it turns out that it is just the opposite, so I will proceed to explain the steps for its replacement easily. But first let's start by reporting on the docking system.

Information about the blender docking system.



The coupling system is important for the functioning of the product, because it is the mechanical part that makes the necessary movements to blend and in the case of the Oster blenders its system is patented. Let's know the functionality of the parts I'm going to replace:

- The quadrant kit.

It is the piece that is in the base of the blender, it is composed of 3 parts:

Square coupling:

All-metal, its function is to directly couple with the grooves of the blade. Its square shape is the one that allows a coupling with greater effectiveness and efficiency for the a blend process.

Coupling Collar:

All-metal, its function is to cover the hole where the kit is located to prevent spills of liquids into the engine.

Rubber coupling:

Part that allows the internal motor to be screwed in with the square coupling. It is made of an elastic band that joins the two metal ends. Its main function is to prevent the engine from being damaged, in the event that the rotation system is blocked by an accident, the rubber will give way and the part will break in two.

To verify that our Oster quadrant kit is original, this one has a manufacturing code.20171228_112634.jpg

- The blade.

The blade is the piece that is in the glass container, below it has an opening that engages directly with the square coupling. This blade has a very well crafted rivet and its design allows to increase its tolerance to ice crushing.

To verify that our blade is original we must check the appearance of the box and the blade, although it is often very difficult for a person without knowledge of blenders to determine its originality. (The images show an original blade distributed in Venezuela, made in Mexico).

Now replace the coupling of the Oster blender by wear.

The first step is to turn the blender over and remove the special screws with the help of a hexagonal screwdriver from ¼. After removing the screws and cover, we were able to see the components.

The propeller in the engine must be removed. To make this step we hold the propeller firmly with our hands and with a pressure wrench we turn the nut to unscrew it.

Now we see the motor shaft protruding from the base. This shaft is held in place with a pressure wrench and the blender die is held in place with another pressure wrench.

To unscrew the square coupling, proceed as shown in the picture: in our right hand we will hold the key that holds the square coupling and with the left hand we will hold the motor shaft, turning the right hand counterclockwise and the other hand in a clockwise direction.

We already took the square coupling out of the blender, now we place our new pieces, for this we leave fixed the pressure wrench we have in our left hand and we proceed to screw the piece.

Once the piece is screwed on, we proceed to close the blender. We already have our blender repaired, we put in a new blade and everything is ready to use.

Finally, I recommend that for a longer durability of the parts:


  • In the case of blending with ice, it must be crushed before placing it in order not to wear down the blades as soon as possible.

  • When the liquefaction process is finished when the product is switched off, the axle continues rolling for approximately 5 seconds due to the impulse. It is necessary to wait for this impulse to finish in order to dismantle the glass cup and thus avoid its rapid wear on both parts.

Friends steemians we have finished another post about how to repair an appliance, in the case of today's Oster blender. It is still my pleasure to present my expertise to provide you with detailed information on repair procedures.
