Update on my hydraulic tank leak. I ended up taking tank out and putting new shaf,seal,new gaskets on the blade tilt control rod and valve body, put back together and installed then other shaft was leaking bad.pulled it off again and replaced the shaft, gaskets and the seal for the blade raise control.No leaking now! I did have to take belly pans off because there was a leak on the underside hose so you guys were right about checking on hose leaking down there,long story short, its fixed and I am going again with this beautiful old gal! I love this lady! I am posting some pictures of the seals and the machine. There’s a difference in caterpillar seals and national seals,the double lipped seal is the caterpillar seal, much better seal, in my opinion. Thanks for all your help with this issue.Merry Christmas to you all!
