Product Model:

NISSAN 15T FS5W71

Product Details:

1. Vehicle Compatibility: As a core component of the transmission system for Nissan 15-ton commercial vehicles (including heavy-duty pickup trucks and light-duty engineering trucks), it is compatible with the reverse gear system of the FS5W71 manual transmission.

2. Functional Positioning: By engaging with the reverse idler gear, it changes the direction of power transmission, enabling the vehicle to reverse; in conjunction with the transmission synchronizer (for some models), it ensures stable power output during reversing and avoids shifting shock.

3. Application Scenarios: Suitable for reversing operations in heavy-duty logistics transportation, construction site material transfer, urban distribution, and other scenarios. It can withstand frequent starts and stops and heavy-load reversing conditions, and is designed for long-term operation in environments with an annual mileage of ≥200,000 kilometers.

4. Material and Process: Made of SCM415 low-carbon alloy steel, treated with carburizing and quenching + precision grinding process: the tooth surface hardness reaches 60-62 HRC, and the tooth root toughness remains at 28-38 HRC, providing both wear resistance and impact resistance.

5. Tooth Profile Design: Adopts a straight-tooth (spur gear) structure, with a tooth thickness 25% greater than that of the forward gear; the maximum load torque reaches 1800 N·m, meeting the heavy-load reversing requirements of 15-ton vehicles; the inner bore has a rectangular spline structure, with a clearance of <0.02mm with the drive shaft, eliminating the risk of transmission slippage.
