Ok thanks for the speedy replies. The model is MTGHS, the serial is 41377, I think it was made in 2000, it is powered by a 20hp Kohler engine and it has almost 2500 hrs on the clock. (thanks Ruben and Marc)
I removed the PTO today, up and out (thanks Eric) sounds easy when you say it real fast :-P ... I cleaned it all up and will be replacing all the seals tomorrow, the bearings were all pretty good just a little movement in and out, it was only leaking on 1 seal but all seals have worn grooves into their shafts, I was thinking of putting HTB grease inside all the seals maybe it would hold the oil in better or maybe it will just melt and mix with the oil anyway, what do you think?
The hydro seems to be leaking at the lower control shaft, I took the nut off and tried to leaver the arm off with a screw driver but it didnt move and I ran out of time. What is the best way to remove the arm and seal? The whole bolt there moves considerably when pushed in and pulled out, probably 3mm of play is that normal?
