Gear 151.37.303-2A (Z37×30) is used in the transport row of the transfer case of HTZ tractors and is designed to transmit torque in the mechanism for switching transmission ranges.
Installed on the input shaft of the transfer case 151.37.305-4. Inside the gear there are two bearings 213 and two spacer rings 151.37.324-2, and they are secured with a retaining ring 2S120. This design ensures reliable rotation of the gear and the correct position of parts in the assembly.
The small 30-tooth ring gear works in conjunction with gear coupling 151.37.221, and the large 37-tooth ring gear is in constant mesh with gear 151.37.308-2 (Z33). The correct operation of the transport row and power transmission in the transfer case depend on the condition of the gear.
Used on tractors HTZ T-150K, T-151K, T-156, HTZ-17221, HTZ-159K, HTZ-242K and other models with a similar transfer case design.
