Dana Spicer 237256 Disconnect Shaft
The Dana Spicer 237256 Disconnect Shaft is a genuine heavy-duty drivetrain component used within the output-shaft/disconnect assembly of select Spicer Off-Highway transmissions. Designed for demanding industrial and off-highway service, the shaft forms part of the mechanism that transfers—or disengages—power through the transmission output section. Dana/Spicer parts documentation identifies 237256 specifically as the “Shaft – Disconnect.”
The 237256 is found in Spicer Off-Highway T20000-series output-shaft groups, including documented model configurations such as 266126 T20000. Within that assembly, the disconnect shaft works in conjunction with the drive coupling, bearing, retaining rings and output-shaft components to provide the correctly supported rotating connection required by the transmission.
Because this component operates within a high-load power-transfer assembly, proper shaft fit, bearing support and alignment are critical to reliable transmission operation. Genuine Dana Spicer components are manufactured for the dimensional accuracy and durability required in heavy equipment operating under high torque, shock loading and continuous-duty conditions.
