Hand mixers are one of the most important and most useful kitchen appliances. They are used to whip and beat ingredients in making of various cakes and desserts. They mix ingredients in a very short time without clumping. Mixing thick ingredients may eventually cause your hand mixer to break down.
For instance, trying to mix thick dough with a hand mixer may cause the gear wheel to get worn out and they cannot turn the beaters anymore. Heavy loads may cause cog wear and the gear wheel cannot turn the beaters anymore.
In such a case, the gear wheels must be replaced with new ones. To do this, first remove the screws holding the housing cover. Then remove the screws that fix electrical parts to the housing. Here they are. Worn down gear wheels.
For remove gear wheels, motor should be removed first. Then unthread the screws holding the gear wheels and remove them. After removing the gear wheels, clean the motor for better performance. The reason of the excessive dust in this part is the dust particles from the ingredients getting sucked in through the air intake vents.
