LXi and WideBody PTO/Pump Splines

[davidbrady]

Morey,

Thanks for the photo and the report. If it were me I'd replace your pump and pto splines sooner than later. Your photo shows significant wear on the face of each spline. Once the wear progresses thru the hardened outer layer it'll accelerate. It won't take long to chew thru the remainder of the spline width. The wear on the face of the spline looks like it's blued from heat. The heat also does a number to the temper of the steel. IOWs, the material remaining might be significantly softer than what was initially spec-ed.
