Hello all:
While using the backhoe attachment on my 450c track loader the boom function became very sluggish and jerky. It also wanted to float up while digging unless a little down pressure was applied before dipper in. Other functions (stabilizers, swing, dipper and curl) appear to operate normally. Without the back hoe attachment the track loader hydraulics function normally.
I suspect that the boom valve has partially failed. Where can rebuild kits for these valves be purchased? I would buy all of them and change them out as a set since if one has gone away the others can't be far behind.
Thanks in advance for your suggestions.
Rick
