Short Description: Ensure maximum engine structural integrity and optimal compression with this precision-engineered set of cylinder studs and nuts. Essential for those restoring their Dnepr MT-11 to factory specifications and seeking long-term reliability under heavy loads.

Technical Specifications:

• Compatibility: Dnepr MT-11 (Model KM3-8.155.6 and compatible series)
• Manufacturer Code / SKU: MT801102
• Part Type: Engine / Crank Gear (Fasteners)

Purpose and Role in the Motorcycle (based on the original manual):
The cylinder studs serve as the primary anchor fasteners for the engine's upper assembly. Their critical role is to securely bind the bimetallic cylinders (consisting of an aluminium jacket and cast iron sleeve) and the aluminium alloy cylinder heads to the engine crankcase. In a high-torque, air-cooled double-cylinder engine like the MT-11, these studs must withstand immense thermal expansion and contraction cycles without losing tension. Proper installation is vital; the manual specifies a strict two-stage tightening process (Preliminary: 1.2–1.6 kgf·m; Final: 2.8–3.6 kgf·m) to ensure the sealing gaskets are compressed evenly. Signs that these fasteners need attention include oil seepage around the cylinder head base, a loss of engine compression, or visible loosening of the nuts during routine maintenance.

Benefits of Buying:

• Exact Technical Match: Manufactured to meet the original technical manual specifications for the MT-11, ensuring a perfect fit and correct load distribution.
• Thermal Resilience: Designed to handle the extreme temperature fluctuations of the MT-11’s air-cooled system, preventing the "stretching" that often leads to head gasket failure.
• Restored Compression: Replacing worn or fatigued studs allows for precise torquing, which eliminates gas leaks and restores the engine's original power and efficiency.
