Motor pinion with keyway, a spare part for the SAP TC22 meat mincer (code SAPTRI0014). It is the gear keyed onto the motor shaft: it forms the first stage of the transmission in the TC22's oil-bath gearbox, transferring rotation from the motor (self-ventilated, intermittent duty) to the train of hardened steel gears that drives the auger.

• Type: motor pinion with keyway
• Compatibility: SAP TC22 meat mincer
• Code: SAPTRI0014

Replacement is needed when the teeth are worn or chipped, when the pinion has play on the motor shaft (a sign of a worn keyway or seat), or when abnormal noise and vibration are noticed in the gearbox during operation.
