PROBLEM

Show/hide table

The existing final drive and/or wheel sprockets on certain 12K, 140K, 140K2, and 160K Motor Graders can prematurely wear due to not meeting hardness and microstructure specifications. If the existing wheel and/or final drive sprockets wear, they can cause resultant damage to other components in brakes and final drives.
