John, you ask� Quote: �First, is the problem of loosing power-trol fluid into the engine a problem with the gasket(s) on the power-trol housing or is it likely to be a problem with the pump? >>> _That is most likely a seal leaking inside the P/T pump up on the engine governor.. When the leak is a gasket at the rear housing the trans usually ends up overfull not the engine� [SEE #5 below before doing this] Quote: �Second, the manual suggests that I will have to take the PTO off the tractor before I remove the Power-Trol (rockshaft) housing. Is this true or does the whole thing come off in one piece?" >>> _No, the rockshaft housing will come off PTO & all.. Just be careful of bending the front PTO shaft when pulling the rear housing... Before pulling that heavy rear housing you should try just re-sealing the piston.. That can be done by only pulling the P/T rear small valve housing then working the piston out the rear.. [SEE #5 below before doing this] Quote: �Third, I'm assuming the slow leak-down of the lift arms is due to a worn seal on the lift cylinder piston?" >>> _That sounds like the most likely place.. It probably isn�t related to the P/T oil in the engine though.. [SEE #5 below before doing this] Quote: �Fourth, there is no fourth but I'm open to any other suggestions (seals to replace, hints etc) that you might think of�>>> _I would re-seal the pump first then use it a while & if all that�s left is the leak down problem then re-seal the P/T piston.. If re-sealing the pump doesn�t stop the oil into the engine problem then you can address that at the same time as the piston re-sealing job.. You biggest headache will be getting those darn hydraulic lines loose from the rear housing & pump.. Be REAL CAREFUL as most of those lines are hard to came by.. [SEE #5 below before doing this] Quote: �Fifth, this should really be the fourth but I just now remembered it. It seems that running the PTO makes the Power-Trol system loose fluid much faster. I know it eventually causes the engine oil to overfill because it will leak out behind the clutch overnight�>>> _OK after reading this all bets on the above are off� That oil leaking from behind the clutch pulley means the TRANSMISSION is probably over-full & that means the Power-Trol is probably leaking into the trans.. . For that repair the entire rear housing will have to come off.. In that case most likely the leak down & leaking of fluid into the trans could have a common tie & that would be the P/T piston housing cylinder base gasket�� While the rear housing is off I would also suggest you replace the PTO pump seals & also reseal the rockshaft piston� Pull the trans fill/check plug & if it is over full suspect a blown rockshaft cylinder gasket..
