Crankshaft for D49 (8/12/16ChN26/26) Locomotive Diesel Engine
This is a high-performance, heavy-duty crankshaft designed exclusively for the Russian Kolomna D49 series of four-stroke, V-type, medium-speed diesel engines (ChN26/26), widely used in mainline and shunting locomotives (e.g., 2TE116, TGM6, TEM7, TEP70).
Key Specifications & Features:
Material: Forged from high-strength alloy steel or ductile cast iron (nodular graphite iron).
Configuration: Suspended design with fully integrated counterweights for dynamic balance.
Journals:
Main bearing journals: 6 supports
Connecting rod (crankpin) journals: Precision-machined, Ø190 mm (steel) / Ø200 mm (cast iron)
Engine Match: Fits 8-, 12-, 16-cylinder V-configuration D49 engines.
Bore/Stroke: 260 mm / 260 mm (ChN26/26).
Rated RPM: 1000 rpm (operating range: 410–1100 rpm).
Lubrication: Full-pressure internal oil passages for main and connecting rod bearings.
Strength: Engineered to withstand extreme cyclic bending and torsion loads under continuous heavy-duty locomotive operation.
Part Number: 1-6D49.8spch (standard assembly).
