I have a customer with a D7H ser. # 79Z01640 and the blade lifts extremely slow. I haven't been out to it yet but I will check the obvious things; linkage, pressures and flow, cylinder leakage ect. Is there anything else that could cause this? I believe it has a ripper on it, does this use the same pump? I haven't worked on a lot of Cats so not real familiar with the system. Thank you.
