GENUINE JCB CRANKSHAFT 444 ENGINE (Part No. 320/09256 320/03336 320/03375)
This Genuine JCB Engine Crankshaft Assembly (Part Nos. 320/09256 & 320/03336) is precision-engineered to original factory specifications to serve as the core rotating foundation for your 4-cylinder JCB engine.
The crankshaft is the central mechanical spine of your engine's internal combustion system. Converting the linear, reciprocating force generated by the pistons into high-torque rotational movement, it drives the machine's transmission, hydraulic pumps, and accessory networks. In heavy earthmoving applications, crankshafts endure extreme combustion shock loads, torsional vibration, high heat cycles, and continuous mechanical stress. Over time, contaminated oil, bearing journal starvation, or excessive overloads can cause severe crankshaft journal scoring, heat cracking, fatigue fractures, or severe out-of-round wear on main and rod journals. A damaged or worn crankshaft leads to catastrophic bottom-end engine knock, rapid oil pressure drop, and complete engine failure if unaddressed. Replacing a damaged crankshaft during an overhaul with this Genuine JCB assembly restores precise stroke timing, reinstates correct hydrodynamic oil clearances, and ensures long-term structural integrity under severe job site conditions.
Manufactured from high-tensile drop-forged micro-alloy steel, this Genuine JCB crankshaft features induction-hardened journals, precision-drilled internal oil galleries for continuous bearing lubrication, and dynamically balanced counterweights to minimize engine vibration across all working RPM ranges.
