PROBLEM

Show/hide table

The existing 1790736/">179-0736 Rear Spindle can crack in the bell area of the casting inboard of the brake flange on certain 773D and 773E Off-Highway Trucks. If the existing rear spindle cracks through the casting wall, it can result in an oil leak. This service letter covers cracks in the bell area only, see photo below.
