Short Description: Restore your engine's breathing and efficiency with this precision-engineered Rocker Bolt and Nut set. Essential for maintaining perfect valve clearances, these components ensure your Dnepr MT-11 operates with maximum power and minimal wear.

Technical Specifications:

• Compatibility: Dnepr MT-11 (and compatible MT series models)
• Manufacturer Code / SKU: MT801515-A (Bolt) / MT801516-A (Nut)
• Part Type: Engine / Valve Timing Gear

Purpose and Role in the Motorcycle (based on the original manual):
The Rocker Bolt and Lock Nut are fundamental components of the Dnepr MT-11's overhead valve (OHV) timing system. Their primary function is to allow the technician to set and secure the exact expansion clearance (tappet clearance) between the rocker arm and the valve stem. According to the technical manual, this clearance must be precisely 0.07 mm on a cold engine. This gap is critical: if it is too small or non-existent, the valve will not seal properly against its seat, leading to loss of compression; if the gap is too wide, the valve opening will be delayed, impairing the cylinder's ability to fill with the air-fuel mixture. Signs that these components require inspection or replacement include excessive "clattering" noise from the cylinder head, a noticeable drop in engine power, or difficulty maintaining a steady idle.

Benefits of Buying:

• Exact Technical Fit: Manufactured to meet the strict specifications of the Dnepr MT-11, ensuring a seamless fit within the valve timing assembly.
• Optimized Engine Performance: Proper installation allows for the precise 0.07 mm adjustment required to maximize combustion efficiency and fuel economy.
• Enhanced Component Longevity: By ensuring correct valve seating and timing, you reduce the risk of premature valve wear and prevent overheating caused by improper combustion.
