Short Description: Restore the heart of your engine with this pair of high-precision piston pins. Essential for any engine overhaul, these pins ensure a secure and smooth connection between your pistons and connecting rods, returning your MT-11 to its peak mechanical efficiency.

Technical Specifications:

• Compatibility: Dnepr MT-11 (and compatible 649cc models)
• Manufacturer Code / SKU: MT801238
• Part Type: Engine / Internal Combustion Components

Purpose and Role in the Motorcycle (based on the original manual):
The piston pins serve as the critical linkage between the engine's pistons and the connecting rods. In the Dnepr MT-11's double-cylinder engine, these are designed as "floating pins," allowing for a controlled movement that reduces friction and wear. The pins are housed within a bronze bushing press-fitted into the small end of the forged, I-section steel connecting rods, ensuring a precision-made fit. To prevent any unintended lateral movement during the combustion cycle, the pins are secured in place by spring lock rings inserted into the annular recesses of the piston bosses. Signs that these pins may require replacement include abnormal "knocking" sounds from the cylinder or excessive piston slap, typically identified during a full engine rebuild or when replacing piston rings due to high oil consumption.

Benefits of Buying:

• Exact Technical Fit: Manufactured to match the strict tolerances required for the MT-11's bronze bushings and piston bosses, ensuring a seamless installation.
• Enhanced Engine Stability: By eliminating excessive play between the piston and the rod, these pins reduce vibration and prevent premature wear on the cylinder walls.
• Complete Cylinder Set: Provided as a pair, allowing you to service both cylinders simultaneously for balanced engine performance and synchronized compression.
