I have 1965 140IH that I bought about 10 years ago. It has been pretty low maintance. The pto seal has started leaking pretty bad. I stopped by the local dealer and picked up a seal today. I went ahead and picked up seal, gasket and bushing to replace the seal on the belt pulley pto also.Are there any tricks to repalcing these seals? It looks like the rear pto seal will pull out without any disassembly and just hammer the new one back in. The belt pulley seal looks like it will take disassebly to get the seal and bushing in place. Are there any tricks? Also, is there a way to drain and flush the gear box without taking it a part. Would I want to do this or would I just be asking for problems? What is the proper way to fill the gear box to get the correct level of oil in it. I've been filling it until I see the gears throwing a good bit of oil around. I thought there might be a side plug some where that you would remove and fill until oil started coming out of the side plug. Thank you for your advice and help.
