Double gear with Z76/Z18 tooth count, size 22, a spare part for Italiana Macchi meat mincers. It is part of the gearbox transmission unit: the larger gear (Z76) receives motion from the motor pinion and, via the smaller pinion (Z18) mounted on the same body, transfers it to the auger that pushes the meat toward the plate.

• Tooth count: 76 teeth / 18 teeth (double gear)
• Machine size: 22
• Compatibility: Italiana Macchi size 22 meat mincers

Replacement becomes necessary when the teeth are worn or chipped, or when the gear has excessive play on the shaft, causing noise, loss of power, or the auger jamming during grinding.
