Short Description: Ensure maximum engine compression and airtightness with these precision-engineered cylinder head fastening caps. Essential for maintaining a secure seal on the cylinder head, these caps are vital for restoring and preserving the power and reliability of your Dnepr MT-11 engine.

Technical Specifications:

• Compatibility: Dnepr MT-11 (and compatible MT series models)
• Manufacturer Code / SKU: MT801309-01
• Part Type: Engine / Cylinder Fasteners

Purpose and Role in the Motorcycle (based on the original manual):
These fastening caps are critical components of the engine's structural assembly. They are used to secure the aluminium alloy cylinder heads and the bimetallic cylinders to the engine crankcase via the anchor studs. In a high-stress environment involving combustion and significant thermal expansion, these caps maintain the necessary clamping force to keep the cylinder head gasket sealed. According to the technical manual, proper installation is mandatory: they must be tightened in a diametrically opposite sequence in two stages (preliminary at 1.2–1.6 kgf·m and final at 2.8–3.6 kgf·m). Signs that these fasteners or the associated head assembly require attention include oil seepage around the head gasket, a drop in engine compression, or audible "popping" sounds indicating a loss of airtightness in the combustion chamber.

Benefits of Buying:

• Exact Technical Fit: Manufactured to the precise specifications of the MT-11 technical manual to ensure consistent clamping pressure across the cylinder head.
• Enhanced Engine Seal: Prevents head gasket blow-outs and oil leaks by providing a reliable, high-torque lock on the anchor studs.
• Durable Construction: Built to withstand the extreme heat cycles and vibrations characteristic of the Dnepr's heavy-duty double-cylinder engine.
