Alright, so my lift leaks down and doesn't seem to want to lift really strong. So I took the cover off the right side and when I lift the 3pt with a little weight on the back there is a drip from the lift cyl. I've got the new NAA piston o-ring and backup washer, but should I replace the safety valve too? I stuck my hand down to feel for fluid seeping by with the pto engaged, and I couldn't feel anything. I'm not sure however that I was really able to find the safety valve. I felt around in there for a few minutes but nothing. Also, is there anything else I should replace while I'm in there? And should I replace the oil? I know I really should replace the oil but it doesn't look bad, and if I can save $50 and not do any harm, well... I have manuals coming so hopefully I can start to figure a little bit of this stuff out on my own. Thanks for the help.
