I fired up the 630 for the first time since complete restoration. She ran awesome but I have a few issues. First the power steering pump that i completely went through is leaking fluid from front seals. Yes I replaced all 4 in the pump. Shocked and depressed to see the drips from many long hours of work. As I started to take it all apart, I noticed engine oil in the fan shaft tube. Another disappointment with my findings. Ive replaced many seals before and not certain where I failed. This tractor was gone through from front to back with new seals and bearings. I was hoping for a leakproof job but failed miserably. Any of you guys have any opinions on my mishaps.
