Juicers are small appliances designed to process citrus fruits into juice. Juice extractors are small appliances that shred various fruits and vegetables and separate the juice from the pulp. Typically, juice extractors are more powerful—and more expensive—than juicers.
Juicers use a motor and gear assembly to drive a spring-loaded shaft and reamer. The reamer activates an internal switch that starts the motor. The rotating reamer rubs against the fruit, releasing juice into a container.
Juice extractors typically use centrifugal force to extract juice through a filter, though some models compress the fruit to force out the juice.
Disassemble a juicer or a juice extractor (standard models):
- Unplug the power cord.
- Remove any parts that come off without tools.
- Remove the base using screwdrivers or wrenches.
- Remove the electrical cord.
- Remove screws holding the motor and switch to the housing and carefully remove the motor from the housing.
- Remove the gears.
- Inspect, test with a multimeter, and replace worn or damaged parts as needed. Refer to the owner's manual for part numbers and resources.
Service a drive system:
- Disassemble, as above, to access the gear assembly.
- Remove the gears and spindle.
- Clean and inspect the gears, checking for worn teeth or other components.
- Replace parts as needed, referring to the owner's manual.
- Reassemble the unit, applying silicon lubricant to the gear teeth.
