The UnitedBuilt S29218MS shaft thrust ring has a 1-3/16-inch inside diameter and 1-9/16-inch outside diameter. It serves the thrust-ring position in the M3ZRM and M3ZRMS shaft assemblies below.
S29218MS is the thrust ring at item 72, separate from the retaining rings used elsewhere in the shaft assembly. Both clockwise and counterclockwise shaft kits use this part in rope-seal and mechanical-seal configurations. Checking its position as well as both diameters helps distinguish it from other rings removed during service.
