Well being Im not sure how to find old questions and answers on here I will once again state my issues and where im at with them. this hoe from the day I bought it never seemed to really have the digging power that I feel it should have. It has always had milky Hyd. fluid and just recently 3 leaky cylinders. I have them off and at shop getting new seals and fixed up. I know I spoke to people on here about flushing how too's but cant find. I have thoughts of while this is down for cylinders buying a new Hyd. pump but would that be a waste of money not really knowing if its bad. I would bet its weak but no clue how to check or where to check. I'm guessing its original pump but not sure. I know getting system sealed up is first step, and i guess flushing properly would be 2nd step. Oh and the leaking cyl's were one up front for bucket curl, one on side for bucket raise, and one outrigger. Any help,pic's, advice would be greatly appreciated. 1977 580C, mech. shuttle, 2wd machine. Thanks
