Ford CL 340 Skid Steer Loader Axle Drive Gear ERK 26060 Erickson CL40. This is the splined gear that drives the axle shaft. It will fit either side, front or back. This is in excellent used condition with good splines and gear teeth as seen in the pics. I am parting the machine, so if there are other parts you need, message me. Thanks for looking and feel free to ask any questions.
