Short Description: Restore your motorcycle's drivetrain to factory standards with this professionally refurbished four-speed gearbox. Engineered for reliability and precision, this unit ensures smooth gear transitions and optimal power delivery for heavy-duty sidecar operation.

Technical Specifications:

• Compatibility: Dnepr MT-11, KM3-8.155, 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 a fundamental component of the Dnepr MT-11's transmission system, responsible for transferring torque from the engine crankshaft to the main drive. This double-shaft, four-speed unit is specifically designed to handle the high loads associated with a heavy-duty road vehicle and sidecar. It features a complex internal architecture including a primary shaft, a secondary shaft with splined sleeves, and an integrated reverse gear (ratio 3.67) for stationary maneuvering. A critical integrated feature is the automatic clutch release mechanism, which reduces mechanical shock during shifts. Signs that your current gearbox requires replacement or restoration include "self-disengagement" of gears (popping out), excessive noise or jerks during shifting, or oil leakage from the primary shaft glands or the gearbox breather.

Benefits of Buying:

• Exact Factory Fit: Fully compliant with the original technical specifications, ensuring seamless integration with the engine and main drive without the need for modifications.
• Enhanced Shifting Reliability: Being a restored unit, it addresses common wear issues in the gear teeth and shift forks, eliminating the frustration of gear slippage.
• Complete Transmission Solution: Includes the integrated starting mechanism and reverse gear assembly, providing a comprehensive upgrade to your motorcycle's drivetrain performance.
