Looks like you are figuring out the machines problem and getting the work done have a wonderful day Max Roy!

Yeah. Thank you William. Have a wonderful day to you too. Bringing this machine on the workspace to service and change the bearing including the seal group. I noticed the problem is coming from the seal group. There is a gear oil leak between the final drive and travel motor.
