I'm new to the forum but I grew up running an AC7045 for my dad's farming operation in South Texas. I run two 7045's with my hay business now. One has developed a hydraulic leak in front of the fire wall so to speak that appears to be leaking between the top of the clutch housing and the mechanism for the high low shift button on the floor. My question is if I disconnect the three hydraulic lines that run to it and take off the brackets and springs for the clutch pedal will I be able to lift this mechanism and find a gasket that needs to be replaced or what will I find??

There's o rings under there, yes it can be lifted off with the lines removed and clutch cable bracket removed.

That should be the part number for the orings at agco dealer. Need 4 of them, if it's same problem as mine was on a 7040

Thanks for the info. Im used to tearing into things and repairing them myself but I didn't want to lift it up and have springs or other parts come flying out and then not know how to put them back in the right place. I bought this tractor 7 years ago, ran it for 1 year and it spun 2 main bearings and cracked the crankshaft. I split it in the middle of the field, put in a pullout engine from Abilene Machine and it has been running great ever since.
