Short Description: Restore the structural stability of your drivetrain with this high-strength gearbox mounting bolt. Essential for ensuring a secure, vibration-resistant connection between the engine and transmission for maximum reliability on the road.

Technical Specifications:

• Compatibility: Dnepr MT-11 (and compatible KM3-8.155 models)
• Manufacturer Code / SKU: 200274
• Part Type: Engine / Transmission Fastener

Purpose and Role in the Motorcycle (based on the original manual):
The Gearbox Mounting Bolt is a critical fastener responsible for securing the four-speed gearbox housing to the engine crankcase. In a heavy-duty vehicle like the Dnepr MT-11, the interface between the engine and the transmission is subject to significant stress and vibration from the 649cc double-cylinder engine. Maintaining a rigid connection is vital to ensure the precise alignment of the primary shaft and the clutch assembly; any movement or looseness in the mounting can lead to oil leaks at the gaskets, increased noise, and accelerated wear of the internal transmission gears. According to the technical manual, these fasteners must be tightened to a specific torque of $0.6 – 0.8 \text{ kgf} \cdot \text{m}$ to prevent damage to the aluminium alloy threads of the crankcase. It is time to replace these bolts if they show signs of stretching, corrosion, or if the gearbox exhibits unusual movement during gear shifts.

Benefits of Buying:

• Precision Engineering: Manufactured to exact specifications to ensure a perfect fit and maintain the necessary alignment between the engine and gearbox.
• Durable Material: Crafted from high-grade steel to withstand the thermal cycles and mechanical vibrations characteristic of the Dnepr MT series.
• Easy Installation: A standard replacement part that allows you to quickly return your motorcycle to the factory-recommended safety and performance standards.
