[QUOTE="Mitch500, post: 133854, member: 24521"] Hello, Recently got my newly acquired 1995 bobcat 853 going after a bunch of maintenance/unknown condition. I've changed hydraulic filters, case drain filters and fluid, repaired most leaks that I could find. My question is when I push both levers forward it wants to slightly turn to the right when going straight. There is also a minor hydraulic whine coming from the right side drive motor. The sound isn't noticeable/can't be heard if you slightly or slowly drive forward straight, but if you push the levers all the way forward or turn one direction the right side motor whining can be heard. This is forward and reverse. I did notice some minor blue plastic material in the right side case drain filter which I was unsure of, but now thinking about it maybe it's a piece of a seal? How should I proceed with this? Should I pull the drive motor and dissemble it and inspect the seals/metal components for wear? Can a damaged seal cause the whining from high-pressure leaking into a area In the drive motor it's not supposed to be leaking too? Photo of case filter with blue material on it. No metal in filters. Thanks! [/QUOTE]
