I have a 99 powder special 700. I noticed last weekend when I tried to stop the slead killed. Then when I started it again it started moving right away. I inspected the drive clutch and noticed that a part inside the clutch (spider gear? or just spider) had a crack in it. I am guessing that this is what is causing my sled to do this. I am a buget minded person (cheep) and like to do things on my own to keep expences down. How can I fix this keeping in mind that I only paid $1000 for the sled. Do i need a whole new clutch, can i buy the broken piece and replace it my self? Can I have the broken piece welded? Is there too much involved for a shade tree mechanic to do without special tools? any help would be great!
