Q: What JCB models use the 25-220804/990 and 459-M2874 solenoid?
A: The COGENG universal solenoid is a direct replacement for JCB part numbers 25-220804/990 and 459-M2874, designed for use across various JCB backhoe loaders, excavators, and other equipment models where these solenoid part numbers are specified. Applications may include hydraulic system controls, transmission functions, or auxiliary circuits. Always verify the part number against your machine's parts manual or the original solenoid's identification label to confirm exact compatibility before ordering.
Q: What does "universal" mean for this solenoid?
A: The "universal" designation indicates that this solenoid is engineered to function as a direct replacement for multiple JCB part numbers (25-220804/990 and 459-M2874), which may have been superseded or cross-referenced across different machine models and production years. This consolidation allows one solenoid to cover several applications, simplifying parts inventory and ordering.
