Short Description: Restore the shifting precision and power delivery of your transmission with this high-grade Secondary Shaft. Essential for those rebuilding their gearbox to ensure reliable gear engagement and smooth torque transfer.

Technical Specifications:

• Compatibility: Dnepr MT-11 (and compatible models)
• Manufacturer Code / SKU: MT804401
• Part Type: Transmission / Gearbox

Purpose and Role in the Motorcycle (based on the original manual):
The Secondary Shaft is a cornerstone of the Dnepr MT-11’s double-shaft four-speed gearbox. Its primary function is to act as the output axis of the transmission, carrying the 1st, 2nd, 3rd, and 4th speed gears, as well as the reverse sliding gear. To handle the heavy-duty loads of a sidecar motorcycle, the shaft is supported by two ball bearings and utilizes a specialized bushing system: metal ceramic bushings for the lower gears and a durable bronze bushing for the 4th gear. This shaft works in tandem with splined sleeves and shift forks to facilitate gear changes. Signs that this shaft may require inspection or replacement include excessive gearbox noise (whining or grinding), difficulty engaging specific gears, or oil leakage from the primary shaft splines due to bearing wear.

Benefits of Buying:

• Exact Technical Fit: Manufactured to the precise dimensions required for the MT-11 gearbox, ensuring seamless meshing with the primary shaft and shift forks.
• Heavy-Duty Materiality: Designed to withstand the high torque and stresses associated with heavy-duty sidecar operation.
• Enhanced Gearbox Longevity: Replacing a worn shaft eliminates erratic shifting and prevents premature wear on the associated gear wheels and splined sleeves.
