RE522871 is a crankshaft replacement for JD agricultural farm machinery equipment.This crankshaft replacement is compatible with multiple JD agricultural and construction machinery models, including the 9300, 9330, 9410, 9430, 9510 series, and others and belongs to the 650 Series components.
Material: Typically manufactured from carbon structural steel or ductile iron. These materials offer high strength, toughness, and fatigue resistance, enabling the crankshaft to withstand the immense stresses and impacts encountered during engine operation.
Structure: The crankshaft structure comprises main journals, connecting rod journals, cranks, counterweights, front end, and rear end. The main journals are supported by main bearings within the main bearing housings of the crankcase. Connecting rod journals connect to the cranks, and to reduce mass and centrifugal forces, these journals are often hollow. Balance weights are cast or bolted onto the cranks to counteract unbalanced centrifugal forces and moments, and sometimes also balance a portion of reciprocating inertial forces.
Compatibility: As an OEM replacement part for JD, the RE522871 crankshaft offers excellent compatibility and matching with JD 9300, 9330, and other series models, ensuring optimal engine performance. In some cases, alternative parts from other brands or models may substitute for RE522871, but careful verification of specifications and performance requirements is necessary.
