*Man, I love the projects I get myself into. Diving into fixing the messed up Kubota D902 (separate thread) - I noticed that the tracks had worn the shoulders on the hydraulic drives - both sides of the machine. See photo of right side drive below. *I am assuming that the tracks had either worn to the point they were stretched and tension was not kept up with or ???? *Plan is to get a local welder to TIG up the worn down area and grind back down to correct profile. My worry is distorting the housing with that much welding, but............. I don't have much choice. *The machine has relatively low hours ~ 1,600...........but, it was a rental. And.............as they say - "Nothing parties like a Rental". So I was going to get the drives rebuilt since I will be this far into removing, welding, and ........possibly....... overheating some internal seals. *Does anyone have a favorite drive rebuild place? I have yet to check locally hear in Sacramento, CA. *Any other thoughts are always appreciated. Thanks, Jim
