Could a failing Main Data Dial Rotary Encoder cause the AKAI MPC ONE to have symptom: Main knob broke at the metal pole?

The 'metal pole' described is the shaft of the rotary encoder. This component converts physical rotation into digital pulses; when the shaft shears, the mechanical linkage is severed, making parameter adjustment impossible. Replacing the encoder restores the structural integrity and electrical signal path.

Could a failing Main Jog Dial Knob Cap cause the AKAI MPC ONE to have symptom: Main knob broke at the metal pole?

The knob cap is the user interface that sits atop the encoder shaft. When a shaft breaks, the internal plastic sleeve of the knob often retains the broken metal fragment or sustains stress fractures that prevent a secure fit on a new shaft. A new knob ensures proper friction-fit alignment.

Could a failing Encoder Mounting Nut and Washer Kit cause the AKAI MPC ONE to have symptom: Main knob broke at the metal pole?

The encoder is secured to the chassis by a specific thin-profile hex nut and washer. These are often lost or damaged during a shaft-shear event and are required to prevent the new encoder from wobbling, which would lead to premature fatigue of the solder joints.
