Fast 7DS200K Transmission Spare Parts - Top Cover Assembly & Other Related Components

These spare parts are engineered to Shaanxi Fast Gear’s original specifications, exclusively for the Fast 7DS200K 7-speed manual transmission (7 forward + 1 reverse gear). Built for heavy-duty scenarios like mining, construction, and heavy haulage, they deliver reliable performance and seamless compatibility with the transmission’s top cover assembly and other auxiliary components.

Constructed from high-quality materials—top cover and shift fork parts made of ductile iron, fasteners of high-strength steel, bearings and seals of wear-resistant materials—all parts undergo precision casting, CNC machining, and surface treatment to meet the transmission’s 2000N·m max input torque and 2600rpm rated speed. Strict quality inspections (dimensional accuracy, wear resistance, assembly compatibility) ensure compliance with OEM standards.

Top Cover Assembly Components

Top cover, shift fork shafts (1st/reverse, 2nd/3rd, 4th/5th, 6th/7th gear), shift forks, guide blocks, steel balls, compression springs, interlock pins, and elastic cylinder pins. These core shifting parts work together to ensure accurate gear selection and stable locking, supporting smooth transmission operation.

Other Related Components

Control window gasket, lifting angle plate, reverse/neutral pressure switches, cylindrical roller bearings, dust cover, output flange, speedometer drive/driven gears, and stop rings. They cover auxiliary functions such as sealing, lifting, gear position detection, and component protection.

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.
