on the other side(left side if you are sitting on it) there should be three or 4 bolts holding the sprocket drive bar in, take those out and push the sprocket towards the right side and it will allow you to tilt and pull it out. you didnt really mention which sled.....(unless you mean the 80 citation?!)
actually you don even mention what you are doing, changing the track is what i assumed...
under where the gear was do you see 3 nuts ? remove them and pull plate off . you should now see the bearing . if you have loosend the retainer on the left everything should shift to the chaincase side and then drop down the shaft on the left and slide it out . sorry to leave you hanging ... I just got back from a bike ride
I did a track swap on my yamaha this spring and this is how it went. Remove speedometer drive cover, look on the inside of the tunnel on left side and loosen the two set screws on the bearing collar. Remove the chaincase cover bottom sprocket and then the inside cover. The drive axle just slid right out for me then. I took it to the right and then tilted it down and out to the left. I don't know how similar this is to your citation but I wouldn't think that they'd be that different. Should be similar anyways.
