Unfortunately, if it is a Coleman Mach, the squirrel cage hangs a single spindle. You can easily tighten it and the compressor fan while you are up there.
You will need a Torx to remove the ac cover( at least on mine), a small socket with extension to remove the cover protecting the squirrel cage.
You will also need a Phillips or flat blade too.
Might need a small roll of foil tape if the old tape is compromised.
When Iím on the roof, I use a small bucket with tools and hoist it up with a line. THEN I have DW throw stuff up when I forget stuff
