Actually, pretty easy to ascertain which screws need to be removed. Just unscrew one and if it's long, those are the ones to remove, if it's short, put it back in because those are the ones that secure the headliner to the ROPS frame. It will be every other long screw.You need to take the roof off to access the ac on your tractor. It’s not hard. Look on the parts breakdown to identify which screws to remove it.
One thing to keep in mind and that is, you'll probably have to replace the perimeter gasket because when the roof is in place, it compresses it and it won't expand again. I replaced mine the first time, I believe the gasket then (with the corner pieces) was around 100 bucks and it's a dealer (Kubota part) item.
The other issue you may have is the OEM Riv-Nuts in the roof may be loose. I replaced them as well with new ones plus I 'glassed' them in for added strength.
Finally, you won't be able to remove the blower or blower housing without breaking out the AC evaporator and the heater heat exchanger is easy, the evaporator isn't. You would have to remove it which means you would have to recharge the ac system and add PAG oil.
What I did was I loosened the top blower housing and propped it up with a wood block which allowed me access to the evaporator and heater coil and I used a handheld pump sprayer with diluted Purple Power and soaked them down and then used clear water to rinse them out and flush the debris down the pan (underneath) which also flushes out the drain tubes. I rinsed it until the discharge water (from the drain tubes was clear.
Like I said, I did a thread on here or on OTT detailing the procedure. I clean mine every spring now. My seed house buddy down the road with his big JD's does the same thing every year.
When you take the top off, remove the outside filter and take a hard look at the gasket. I replace mine every year as well. If the gasket don't seal the filter completely, dirt will get in pretty quick. I used closed cell expandable foam with adhesive on one side to replace mine. Any box store will have it as well as the Reflectix.
