Ive just done this to my old 7045.
I took off the seat and the cover for the inner and outer hydraulics.
Then I removed the lower back window.
Off with the floor where the gear levers are.
Disconnect handbrake/pto clutch cabels from body.
Then i removed the floor under the seat.
Now you should have acces to the cover plate.
You will have to disconnect the lift arms from the cover, put a mark on them so you know where they went.
Undo all bolts from the cover.
Now you are ready to lift the cover plate up and out.
I tilted the roof and put a 2x4 over the cabin, connected a hoist to the 2x4 and lifted it up and the pulled it backwards behind the tractor.
Nothing falls off when you lift the cover. There is at connector tube with o-rings that distibutes
oil from the body to the cover. Its mostly stuck to either cover or body, change the o-ring before assembly.
I might have forgotten some small stuff but you will see it when you get to there.
Some say you only need to tilt the seat and floor forward against the steering wheel to get access to the cover. I took my time and did it this way.
Also when you start to dissasemble the cover you need to take notes/pistures of where everything goes. I removed the lift cylinder and then pushed the lift arm mechanisme to one side. Take note of where the bushings and gasket goes,
Let me know how it goes and ask if you need more
help.
