Short Description: Ensure the structural integrity of your engine's bottom end with this high-strength connecting rod bolt and nut set. Essential for a professional engine rebuild, these fasteners provide the precision clamping force required to restore peak performance and reliability to your Dnepr MT-11.

Technical Specifications:

• Compatibility: Dnepr MT-11 (and compatible KM3-8.155 series models)
• Manufacturer Code / SKU: MT801257-a_MT801259
• Part Type: Engine / Crank Gear

Purpose and Role in the Motorcycle (based on the original manual):
The connecting rod bolt and nut are critical components of the engine's crank gear, specifically used to secure the detachable, asymmetrical big end of the connecting rod to the crankshaft crankpin. In the Dnepr MT-11's four-stroke, double-cylinder engine, these fasteners hold the connecting rod cap and interchangeable bronze bushings firmly in place, allowing the piston to transfer combustion energy to the crankshaft. Because the connecting rod caps are not interchangeable and operate under extreme reciprocating stress, using high-quality fasteners is paramount. Failure or improper tightening of these components can lead to premature wear of the crankpins or catastrophic engine failure. These should be replaced during any major engine overhaul, particularly when replacing connecting-rod bearing bushings to ensure the long-term service life of the crankshaft.

Benefits of Buying:

• Exact Technical Fit: Manufactured to match the strict specifications of the Dnepr MT-11, ensuring a perfect fit for the asymmetrical big end.
• Precision Torque Compatibility: Designed to withstand the specific tightening torque of 3.2 – 3.6 kgf·m required by the technical manual for maximum security.
• Restored Engine Stability: Using new, high-grade hardware eliminates the risk of fastener fatigue, providing peace of mind during high-load operation.
