go buy a 10-12" long threaded bolt with a couple of big washers to help hold the spring cap in place, the springs are not that hard to change but the bolt will make it a lot easier and you have to watch the cap bushing don't F it up there an exspensive little bugger
If you mean by breaking it down your going to need a grunt tool and a clutch holder then you can split the spider, then change the inner bushings and the clutch buttons as thyey have been in there since the sled was new, make sure everything is nice and tight if your going to be running radar runs your going to need everything your sled has to offer
I found if you wash your clutches in hot soapy water they come very clean no belt dust of any sort then spray it down with brake clean
