xf 2500 quad loop . My right side pump blew so I replaced it with a new one now when I try go forward and back it feels like it is binding and not turning the wheel. I took the wheel motor apart and found metal shavings. I cleaned the motor and put it back together and still the same thing. the pump is trying to move it and is staining forward and back and the wheel moved a tiny bit but still nothing. any idea's. thanks
