I removed the transmission cover on my 340 tonight since it was hytrans leaking through the gasket. The man I purchased the crawler from had recently replaced the steering clutch shoes. However I discovered that the rotors that form the planetary sun gears are badly grooved, causing accelerated wear on the shoe linings. Can these rotors be taken out and touched up in a lathe? I would remove just enough material to make them smooth again. Also, can these rotors be removed without taking apart the final dive housings. I just replaced the brakes on this machine and it was quit a chore, I would rather not have go through all that disassembly again. Your advice is greatly appreciated.
