Main Drive Shaft Key (6mm)
Function group: Hardware
Small but critical. This key ensures that 100% of the motor torque is transmitted to the separator bowl. If this part shears due to a sudden jam, your motor will spin but the milk won't separate. Always keep a spare on hand.

About the Hardware group
Hardware covers the fasteners, mounts, feet and alignment items that hold the machine together and damp vibration. Missing or incorrect fasteners should be replaced rather than substituted with a similar-looking item.
Selection notes for this entry
- A material is stated for this entry: check the marking on the delivered part against it before fitting.
Checks before you order
- Confirm the fastener type, thread and length against the one removed — similar-looking items are not interchangeable.
- Check mounts and feet for hardening, splitting or compression set.
- Replace missing fasteners rather than leaving a position empty.
