I am new to the forum and have tried the search button but couldn't find the info I need. I have a 1973 580B that has a leak between the torque tube and the transmission. It leaks all the fluid out of the torque tube over night. I have the gasket but I am not sure the best way to install it. I have been told to take the backhoe off and split it that way but I have also been told not to over complicate it and just unbolt the torque tube from the tranny and slip the new gasket in. I also was told to cut the top of the gasket and slip it in. Any advice would be much appreciated. Thanks in advanced!
Have you checked to determine if the bolts are all tight ? If they are tight, I think I would try cutting the new gasket at the top and replace it that way. Use black RTV on the gasket and let it cure a while before tightening the bolts. Otherwise it is easy to squeeze most of the RTV out of the sealing surface.
