Product Model:

33318-OW010 HINO M012

Product Details:

1. Applicable Vehicles and Systems: Designed specifically for the M012 manual transmission of HINO 500 series medium and heavy-duty commercial vehicles (including dump trucks, refrigerated trucks, and construction trucks); serves as the main drive gear for the 4th/5th gear of the transmission, engaging with the synchronizer and output shaft gear to transmit power.

2. Material and Process: Made of SCM415 low-carbon alloy steel, processed through forging + carburizing and quenching + precision grinding: the tooth surface hardness reaches 60-62 HRC, while the base material maintains a toughness of 28-38 HRC, balancing wear resistance and impact resistance; the internal structure is dense and pore-free, and the fatigue strength is increased by more than 40% compared to ordinary cast gears.

3. Structural Design: The inner bore features a rectangular spline structure, with a fit clearance of 0.01-0.02mm with the drive shaft, ensuring slip-free transmission and stable torque transfer.

4. Functional Positioning: Achieves linear conversion of speed and torque, optimizes power output smoothness, reduces shifting shock, and extends the service life of transmission components such as synchronizers and bearings.

5. Applicable Scenarios: Suitable for high-frequency start-stop and high-load conditions such as urban logistics distribution, intercity heavy-duty transportation, and construction site material transfer.
