Product Description
These component parts are engineered to Shaanxi Fast Gear’s original specifications, exclusively for the Fast 12JSD180TA 12-speed manual transmission. Built for heavy-duty scenarios like long-haul transportation, mining, and construction, they deliver reliable performance and seamless compatibility with the transmission’s core assemblies.
Constructed from high-quality materials—clutch/transmission case parts of ductile iron, second shaft and countershaft of alloy structural steel, sealing components of wear-resistant rubber—all parts undergo professional processing. Case parts adopt precision casting, CNC machining, and leakage testing; shaft and gear parts go through forging, heat treatment, gear hobbing-grinding, and shot peening reinforcement. These processes meet the transmission’s 1800N·m max input torque and 2600rpm rated speed requirements. Strict quality inspections ensure full compliance with OEM standards.
Clutch & Transmission Case Assembly Accessories
Clutch housing, transmission case, skeleton oil seal, hex bolts, gaskets, positioning pins, and bowl-shaped plugs. These parts form the transmission’s outer protection and sealing system, ensuring structural stability and leak-proof performance.
Second Shaft Assembly Accessories
Second shaft, synchronizer assemblies, elastic cylinder pins, stop rings, gear spacers, and hexagonal keys. Core power transmission parts that work with gears to achieve smooth shifting and stable torque output.
Countershaft Assembly Accessories
Countershaft, countershaft drive gear, square keys, needle bearings, and thrust washers. Adopting dual countershaft power split design, they evenly distribute torque to reduce gear stress.
As direct-fit parts, they require no modification for installation, perfectly matching the original assembly structure and reducing maintenance downtime. Fully interchangeable with original equipment, they’re ideal for routine servicing, emergency repairs, or fleet maintenance. We provide professional after-sales support and technical consultation for reliable heavy-duty operation.
