Short Description: Restore the robust drivetrain of your classic Dnepr MT-11 with this precision-engineered four-speed gearbox. Designed for heavy-duty sidecar operation, this unit ensures reliable power delivery and effortless maneuvering in any terrain.

Technical Specifications:

• Compatibility: Dnepr MT-11 (Model KM3-8.155.6 and compatible models)
• Manufacturer Code / SKU: KM3-8.15604000
• Part Type: Transmission / Drivetrain

Purpose and Role in the Motorcycle (based on the original manual):
The gearbox is the central hub of the MT-11's transmission system, responsible for transmitting torque from the engine crankshaft to the main drive. This double-shaft unit features four forward speeds and a dedicated reverse gear, a critical necessity for the heavy-duty nature of a motorcycle-sidecar combination. It houses a complex system of primary and secondary shafts, shift forks, and a slot-cam gearshift disk that allows the rider to manage tractive force efficiently. One of its most vital roles is the integration of the automatic clutch release mechanism; this system reduces the physical load on the rider by automatically disengaging the clutch during gear transitions. Signs that the gearbox requires overhaul or replacement include excessive noise (cracking) during shifting, "self-disengagement" of gears (popping out of gear), or oil leakage from the primary shaft glands.

Benefits of Buying:

• Exact Technical Match: Manufactured to strict factory specifications for the MT-11, ensuring seamless integration with the existing engine and main drive.
• Enhanced Maneuverability: Includes the essential reverse gear assembly, allowing you to navigate tight spaces and reverse your sidecar combination without external help.
• Heavy-Duty Durability: Built with a combination of high-strength metal-ceramic and bronze bushings to withstand the high loads associated with heavy-duty road use and sidecar weight.
