Description
Centrifuge locking nut for Chayka washing machines (left-hand thread M8)
Original shaped nut for securing the centrifuge (spin) tub is designed for reliable fixation of the centrifuge rotor/basket on the motor shaft in twin-tub semi-automatic washing machines "Chayka", "Volna" and their analogues. Made of special impact-resistant and moisture-resistant pressed material (bakelite/textolite) with an internal brass or steel threaded insert, resistant to laundry detergent, hot water, and vibrations.
Key advantages and features:
- Left-hand thread (LH, M8): The special thread direction prevents spontaneous loosening of the nut during high-speed rotation of the centrifuge during the spin cycle (clockwise).
- Ergonomic shape with side "ears" (wing nut): Allows for easy tightening and loosening of the nut by hand without the use of special tools, without damaging fingers or the internal walls of the tub.
- Resistance to aggressive environments: The thermoset plastic body is not subject to corrosion and does not swell from constant contact with water and detergents.
- Protection of laundry from snags: The smooth rounded dome shape prevents damage and tearing of items during loading and centrifuge rotation.
Signs that the centrifuge nut needs replacement:
- Stripped or damaged internal left-hand thread, resulting in the nut spinning on the shaft and failing to secure the tub.
- Mechanical damage to the "ears" or cracking of the nut body from long-term use.
- Loss of the part during preventive disassembly or cleaning of the spin unit.
Compatibility and scope of application:
Used in Soviet and classic semi-automatic washing machines with a centrifuge:
- Washing machines: Chayka (Chayka-2, Chayka-3, Chayka-85), Volna, Aurika, Sibir, Oka, as well as some models of compact washing machines like "Malyutka" and "Feya" with a similar M8 shaft with left-hand thread.

Pro tip: Remember that the nut has a LEFT-HAND thread: it is tightened counter-clockwise and loosened clockwise. When screwing the nut onto the shaft, do not use metal wrenches or excessive leverage to avoid stripping the internal threaded sleeve. It is sufficient to tighten the nut firmly by hand with slight effort.
