yanmar ym177
Finally after 8 years my 177 is having problems. Seems almost overnight my hydraulics began getting slow, low powered, and choppy. I bypassed all the bucket controls and aftermerket hydraulics. The rear box is still choppy and slow but useable. All fluids were full and no air appeared in fluid. I removed the pump and feed lines for inspection. No cracks in line or broken parts in pump. I havent taken the pump apart but i can seen the gears are ok. Both knobs under and by seat are in the correct position. I cant find any screen or filter in the system. Any help would be apreciated and pics are available. thx.
