Using the great information from this site, I re-built my 520 power steering pump. I used a brand new fan shaft, installed new bushings, new seals, two on each end "back to back". The pump works great, but still leaks on the front end, fan side. I am using the John Deere power steering fluid for tractors built before 1960. I was clean and careful with the seals. What would you try next? I cannot stand a leak.
