AGCO - 3619762M1 - Gearbox Solenoid Pin Massey Ferguson

This gearbox solenoid valve plunger is the moving core that translates an electrical signal into a mechanical action inside the transmission. It sits inside the solenoid coil mounted to the wet clutch and gearbox assembly; when energized, it shifts to open or close a hydraulic passage that directs oil pressure to a clutch pack. A worn or stuck plunger causes delayed or harsh gear engagement, or a complete loss of drive in a specific range. The manufacturer machines this component to the same diameter and surface finish as the original assembly, so the solenoid's magnetic force and stroke remain within the design tolerance. No shimming or adjustment is required during installation; simply transfer the O-ring from the old plunger if it is reusable, or fit a new seal.
