I had to move the 318 to get a model 49 ST out from behind it. There was a sizeable oil spot under the right tire from leaky seal. That will be the next project on this tractor. Maybe this weekend. Already have a seal. Hope that is all I need. Just looking at the right side brakes and differential I see same issues with previous service. Appears that a PO replaced brake shoes on both sides and reassembly was not correct. Soon to find out for sure.
