Lock ring D70 for Terex TX760B

The lock ring, part number 6194411M1, functions as a mechanical fastener within the transmission system of the Terex TX760B backhoe loader. It is specifically located in the transmission second shaft four-wheel drive assembly. The ring is designed to fit a 70-millimeter diameter shaft or housing, where it sits within a machined groove to provide a positive stop for internal components.

This component ensures that gears, bearings, and bushings remain in their correct axial positions during operation. By preventing unwanted axial movement, the ring maintains the alignment of the transmission shafts and internal drive elements, which is necessary for the proper distribution of power to the wheels. It is installed using standard retaining ring tools and provides a secure fit once seated in the groove.

Lock rings are used throughout heavy machinery to secure rotating or stationary parts on shafts and within bores. By creating a shoulder, they effectively lock components in place, preventing them from sliding off the shaft or out of the housing under operational loads. Proper installation of this ring is necessary to maintain the structural integrity of the transmission assembly.
