How do I determine pin/bushing wear on my 955H 60A4149, is it obvious?
From what I was told I have asphalt 3 grousers pads? I did the drive spocket when I first got it but was wondering how do I determine the condition of the rest of the undercarrige?

My Cat dealer up here isnt too interested unless I'm spending millions (literally) but a company called Union Tractor bends over backwards to help me, but I live a ways out of town.

You can check for pin and bushing wear by the attached chart.
Place a pin between the sprocket and rail to take out all the slack and measure.

Much appreciated, Thankyou
