Yanmar YANMAR -8N21 - CRANKSHAFT
Crankshaft is the primary rotating component of the engine that converts the reciprocating motion of the pistons into rotary power. Manufactured from high-strength forged alloy steel and precision-machined to exact tolerances, it ensures smooth power transmission, durability, and long service life under demanding marine operating conditions.
Suitable for YANMAR N21, 6N21, and 8N21 marine diesel engines used in marine propulsion, auxiliary generator, and industrial power applications. Crankshafts are commonly supplied in standard size and may be available as new, reconditioned, or serviceable units subject to inspection and testing.
