I can't remember the sizes but you also need some large sized metric sockets and an adjustable wrench since you'll have to get the bed off of it to change the clutch out. Don't forget a lug wrench as well and jackstands as you need get the rear wheel off.
I have a large Stanley toolkit (http://a.co/1w4yUxi
) , a larger adjustable wrench, and a Torx bit set that I keep near my Gator... seems to cover almost everything. A Drill/Driver and Impact wrench are also helpful. The Drill/Driver is better for the trim screws so you run a lower risk of stripping out the threads when putting them back in.
Also, you need a clutch puller tool... JDG 1641 should be the right one for the Primary Clutch; JDG11200 only fit my driven clutch but was what the dealer sent me; as a side note, my local dealer said they "can't" sell me either tool. I made the puller for use on the primary clutch using the instructions in another thread (https://www.gatorforums.net/forum/gat...850d-855d.html
). I used a 7/16 diameter bolt in place of the 1/2" bolt. It took about 5-10 minutes with the angle grinder and a dremel to cut the bolt, bevel the edges, and smooth then ends. I used #8 bolts for both... don't forget the anti-seize on the threads and to lubricate the ends.
Also, be prepared for some busted knuckles, I swear that they make this as hard as possible to do at home. I definitely needed to pull all the body panels and the bed plus loosening the air cleaner housing to get enough space to work on the clutch. It was just time consuming to get everything off and the clutch out... although there was that break when I discovered that JDG11200 didn't work and then needed to source/make the right tool.
