Working on my 400 row crop which started out great put the belt pulley assemble on, ordered parts wrong part. then I noticed the right rear brake did not hold. So I started on the left side looked like oil leak, pulled the cover and it was full of grease, I mean packed. So I ordered parts for both sides. Took the inter plate off and well the bearing was rusted. So now I am waiting on bearings for both sides. I will pull the trans apart after I work it awhile and see if the noises go away. The tractor runs great but it did not have the care it should have, but I will get it back in shape. Jerry from Ohio
