Congrats on your purchase! Based on the hours and the loader usage...you probably are looking at a clutch job..you've had good advise on the the "how" as far as "splitting"..As a starter, get a GOOD Agco MF Service Manual for the 150...there's a bunch of MF dealers you can get parts, but go to that "-bay" auction site and plug in "Massey Fergusen 150"...you will need about an hour to go thru all the stuff you will find...including clutch packs.. (I've got a MF 135 ('67))...I believe they use the same clutch as the the engines are pretty much the same as are the trans...also look under the 135s as the parts are interchangeable to a great extent...Good Luck! send pics...BobG in VA
