When these seals fail does it have anything to do with the pile of dirt that builds up on top of the axel and that the seal then has to run in all the time? I had to change one once on a CM225. It looked like the rubber on the seal was damaged some, maybe because of the dirt pile. I made 4 dirt shields out of 1/8 x 2" flat bar and pop riveted a strip of rubber belting onto each steel strip. I clamped one onto each axel end with a big hose clamp where the wheel hub turns and it seems to work very well since then. The rubber just rubs on the flat part of the wheel hub and any dust that gets in under the shield just falls out the bottom half that is still open. The pile of dirt does not feed directly into the seal area.ive got a 9370 steiger with 6000hr on it, I have two wheel seals leaking one at the front and one at the back. I was thinking of maybe doing all four and reversing planetrys aswell, do I move planetrys diagonally or from one side to the other?
