I have what is supposedly an early Town and Country trike rear end. It is a 2 piece deal, single wheel drive (left). I wasn't sure when I bought it but I do see Campus Green paint under the black spray paint. Has anyone taken one apart? I want to grease the bearings and slide the sprocket over to get the chain aligned. It looks like a set screw and roll pin need to be removed. Any help would be great. I'm adapting this to my wife's Spaceliner.
