Keyed shaft installed
Disassembly Steps
- Position the shaft so the key faces downward, then secure the key in the vise jaws.
- Firmly pull the motor/shaft assembly straight upward to separate it from the key. If the key is tightly fitted, apply a small amount of penetrating oil and allow it to soak before attempting removal. Do not use excessive force.
Precautions for Disassembly
- Follow all steps in order. Do not skip any steps.
- Be careful to avoid damaging the shaft surface when clamping.
- Ensure safety: During disassembly, always wear appropriate personal protective equipment (PPE), such as gloves and safety glasses, and keep hands clear of pinch points to avoid injury.
