I had an employee blow a hydro line, ran it pretty low on oil before shutting it down. After replacing line and refilling, the main pump was a little noisy. So I replaced with a new remanufactured Komatsu pump. Now I have no reaction on the lift or bucket. No reaction on steering either. Now before the line blew, it had a slight leak from a seal dumping into the transmission (like most of the machines develop). When bleeding the air out, the main bleeds fine. the steering/lift side is aerated quite bad. Pump shaft seal was replaced but still dumping into the trans.
I've had a mobile truck service guy working in this and he is at a stand still for finding the problem. Hydro tank was drained and nothing abnormal came out. No excessive metal or anything. This was a cab off pump change.
Anyone with any ideas that is familiar with these machines?
any pointers would be greatly appreciated.
