[QUOTE="neller840, post: 134835, member: 23098"] I have a 335 excavator. The left track has started getting weaker, but only going forwards. Reverse it tracks ok(equal power), but forwards the left track is weak. I've tried easy things: checked track tension, control linkage, checked travel motor case drain. A friend thought it was the travel motor's control valve o-rings. I am no hydraulic expert, and want to diagnose this properly, before I pull a valve manifold off. Any advice as to next things to check? I was going to buy a pressure test kit, but I can't find great troubleshooting steps. I want to get a kit that will have everything needed to test this and other circuits. I know testing flow is really important as well. Any advice on tools to add to my arsenal for troubleshooting this? Thanks for reading and any help you might offer! [/QUOTE]
