JoeM 7,874 #1 Posted April 29, 2020 Anyone familiar with repairing these valves? I have an hydro machine where the forward is not strong, all the ordinary stuff checks out. Oil, filters, adjustment, charge pressure, etc. Tree testing proved the reverse is strong and working as it should, forward just ramps up and whines. I suspect the acceleration valve maybe the issue. Repair or replace? Suggestions. Share this post Link to post Share on other sites
