Short Description: A precision-machined Woodruff key designed to ensure a rock-solid lock between your crankshaft and flywheel. Essential for maintaining perfect engine timing and restoring the peak operational reliability of your Dnepr MT-11.

Technical Specifications:

• Compatibility: Dnepr MT-11 (Model KM3-8.155.6 and compatible series)
• Manufacturer Code / SKU: 7201222
• Part Type: Engine / Crank Gear

Purpose and Role in the Motorcycle (based on the original manual):
The Flywheel Key is a critical shear-lock component located at the rear end of the engine's crankshaft. In the Dnepr MT-11's heavy-duty double-cylinder engine, the flywheel is mounted on a tapered crankshaft journal; the Woodruff key fits into the matching keyway to prevent the flywheel from rotating independently of the crankshaft. Because the flywheel is responsible for smoothing out engine pulses and providing the necessary inertia for the crankshaft, any wear or failure of this key can lead to "slipping," which immediately disrupts the ignition timing and can result in severe engine malfunction. While it is a durable part, it should be inspected during any engine overhaul or if the motorcycle experiences sudden timing shifts or unusual vibrations from the rear of the crankcase.

Benefits of Buying:

• Exact Fit to Specifications: Manufactured to match the exact dimensions of the MT-11 tapered crankshaft and flywheel hub for a seamless, secure installation.
• Restored Timing Precision: Eliminates the risk of flywheel slippage, ensuring your ignition timing remains constant for smoother idling and better acceleration.
• High-Duty Durability: Built to withstand the high torque and rotational stresses characteristic of the Dnepr 649cc power plant.
