so the story goes that the supposed original owner said the lift needed to be rebuilt when he sold it, guy i bought it from said the lift "worked fine" after he replaced the fluid (he put universal tractor hydraulic fluid in it), though he only used it to pull a trailer a couple times...when i hooked up a blade to the 3 point and put the lever all the way up, i could watch the lift arms pull up on the blade, but not lift it at all. pulled the side cover and looked in when the lift was engaged, saw the fluid whirling, so i replaced the relief valve, and changed the fluid to 15w-40. when the tractor was cold, it lifted fine, but as it warmed up the lift got weaker and weaker, and would only lift with the engine at high revs. i had gotten an naa piston to replace the old one already, so i pulled the lift off and looked at the piston, rings were shot. swapped the piston out, and it worked great for a while until i caught the blade on a stump when it was in the up position, since then its been doing the cold good, warmed up weak and will only lift with high revs. thinking the lift cylinder needs to be replaced since the old ring piston was so bad, might have bored out the cylinder a bit...is there anything else i should be looking at? am i on the right track? dont want to just throw parts and money at it until it works, would like to know if i am replacing the right part. thanks guys!
