Heavy Industry 119266-21700 Forged Engine Crankshaft for Yanmar 3TNV84, 3TNV88

   Thank you for choosing SPARKLING MACHINERY. 
   The 119266-21700 crankshaft is manufactured from high-tensile forged alloy steel, with precision micro-ground main journals, connecting rod journals, and counterweights. Micro-finished and dynamically balanced to eliminate rotational vibration, it is induction-hardened to extend bearing life and resist surface scoring under heavy diesel loads. Replacing a cracked, scored, or bent crankshaft during an engine overhaul restores full compression balance, stops oil pressure drops caused by journal wear, and returns the engine to smooth operational performance.
