Description
High Reliability for Severe Heavy-Duty Tasks
Core Specifications & Key Parameter Highlights
Drive Mode & Power Output
Both models adopt 6×4 drive mode for strong traction. The CA6DM2-42E52 (Euro II) offers 309kW (420HP) at 1900rpm. The CA6DM3-46E51 (Euro V) reaches 341kW (460HP) at 1900rpm. Power options span 390HP to 500HP to meet diverse needs.
Gearbox & Transmission Performance
The CA6DM2-42E52 features a 12-speed manual gearbox (CA12TAX210M). The CA6DM3-46E51 uses a 16-speed manual ZF16S2231 TO. Both gearboxes boast high mechanical stability. Their transmission ratio ranges from 12.1 to 0.78.

Climbing Gear & Rear Axle Ratio
The CA6DM2-42E52’s maximum climbing gear is 12.1 (low-speed high torque). The CA6DM3-46E51’s climbing gear hits 12.80 (low-speed high torque). This enhances heavy-load startup and slope performance. The CA6DM2-42E52 has a 457 axle with 4.444 ratio. The CA6DM3-46E51 uses a 300 axle with 4.266 ratio. Large ratios optimize low-speed traction and torque.
Tire Configuration
Tire setups differ slightly between the two models. The CA6DM2-42E52 uses 315/80R22.5-20 tires. The CA6DM3-46E51 comes with 295/80R22.5-18 tires. Both adopt wide-section, high-level tires for heavy loads and rough roads.
Brake System
The CA6DM2-42E52 is equipped with dual-circuit air drum brakes. The CA6DM3-46E51 adds ABS and a retarder to the system. Drum brakes remain an option for lower maintenance costs.

Key Advantages of FAW JH6 Tractor Truck
1. Classic Manual Transmission
Moreover, classic manual gearboxes shine in harsh conditions. They perform well in extreme temperatures and complex terrains. Areas lacking advanced maintenance also benefit from them. They offer unbeatable mechanical stability and easy upkeep. This maximizes vehicle availability for non-stop operations.
2. Heavy-Duty Chassis & Large-Ratio Rear Axle
Additionally, large-ratio rear axles (4.444 or 4.266) pair with high climbing gears. They deliver powerful low-speed traction for tough tasks. This matters for off-road, mining or short-haul heavy-load transport. The tractor handles full-load stuck situations with ease on slopes. It ensures reliable startup even on unpaved surfaces.
3. Diverse Emission Standards & Custom Options
Besides, emission standards range from Euro II to Euro V. The CA6DM2-42E52, for example, meets Euro II requirements. This adapts to different countries’ environmental rules. It simplifies old route upgrades and new market entry. You can customize the tractor to fit specific regional needs.
