Nine times out of 10, travel problems are caused by faulty swivel or Rotary manifold seals by passing within the manifold causing a loss of pressure and flow going to your drive motors. Resealing the Rotary manifold is part of the troubleshooting process with excavator travel problems. If you have resealed the Rotary manifold in this problem still exists, check for excessive case drain pressure from your final drives, especially the problem final drive, as you should have a very low volume of flow of oil from case drain with the track pinned between the sprocket and track chain to prevent movement, and a hose from the case drain port into a 5 gallon bucket. When you engage travel with that drive deadheaded, you should see a low volume of oil. Compare both sides. If it comes out under high volume or pressure, that drive motor has excessive internal leakage in needs to be rebuilt or replaced. It is a pleasure to help anyway I can.
