Mman helped me with my last problem so now I'm on to the next one. I assume the hydraulic pump is leaking into the crankcase cause it keeps getting overfull of oil. When I got it home the oil was way over full. I wasn't sure if it was really that full or if it had the wrong dipstick. I drained the old oil and Got nearly 4 gallons out of it. After putting in the correct amount in I can tell that it is the correct dipstick. After running it a good bit trying to get the RPMs right and adjusting the governor I checked the oil and it is over full and the hydraulic system is now low. After looking at the hydraulic pump breakdown it doesn't list a seal assembly which I assumed was the problem. So how am I getting Hy-fluid in my crankcase? Is there a seal that I don't see on the parts drawing?
