Fast 7DS200K Transmission Spare Parts - Rear Cover & Reverse Idler Shaft, Control Device, Rear Bearing Cover Assembly 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 rear cover & reverse idler shaft assembly, control device assembly, and rear bearing cover assembly.

Constructed from high-quality materials—reverse idler shaft and control lever made of alloy steel, rear cover housing parts of ductile iron, sealing components (oil seals, O-rings) of wear-resistant rubber—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, sealing performance, wear resistance) ensure compliance with OEM standards.

Rear Cover & Reverse Idler Shaft Assembly Components

Reverse idler shaft, reverse idler gear, needle bearing, reverse thrust washer, elastic cylinder pin, O-ring, and mesh filter. These parts work together to ensure stable reverse gear power transmission and effective internal component protection.

Control Device Assembly Components

Lateral shift lever, shift head, compression spring, shift lever bushing, limit sleeve, and low/reverse gear switch control block. Designed to match the transmission’s shifting mechanism, ensuring precise and smooth gear selection.

Rear Bearing Cover Assembly Components

Rear bearing cover gasket, oil seal, hexagon head bolt, spring washer, and main shaft rear bearing cover. Core sealing and fixing parts that prevent oil leakage and dust intrusion into the transmission.

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.
