XA10604-1
Rack Plunger
SAF-Holland

This pair of plunger assemblies functions as a critical actuation element within the latching mechanism of heavy‑duty trailer couplings. The included two units are engineered to deliver consistent travel and feedback to the rack and gear set that governs release, ensuring symmetrical motion and balanced engagement forces across the jaw system. The embedded product attributes specify a component family classification, reflecting their role as secure, removable actuators within the overall assembly. The published VMRS code 059-001-027 identifies their placement in the release subsystem, underlining their importance in reliable cycle initiation and return to safe positions after uncoupling. Installation typically requires precise alignment with mating components and adherence to torque and clearance specs, enabling predictable performance under load, vibration, and temperature fluctuation. The details field notes safety warnings associated with handling and installation; technicians should consult Prop 65 guidance and follow recommended PPE to mitigate exposure during service. No cross references are listed, which simplifies replacement by offering a direct fit within the supported components family, when used in conjunction with compatible rack and latch assemblies within the same category context.
