The tie rod with code 11.01295-0276-1.C is a critical structural fastener in the MAN L21/31 engine, designed to clamp the cylinder block, crankcase, and cylinder head into a rigid and precisely aligned assembly. Manufactured from high-tensile alloy steel, this component maintains uniform clamping force across the engine structure, even under extreme combustion pressures and thermal expansion. Its strength and dimensional accuracy are essential for preserving engine geometry, minimizing vibration, and preventing leakage, making it a cornerstone of long-term engine reliability in marine propulsion and power generation applications.
