I too found lots of water/moisture inside the clutch housings and removed the drain plugs. I only use the machine for a couple of hours at a time and the clutch is used just to turn the machine around and for corrections when under way. I intend to re-re the clutch once the warmer weather arrives in the spring. Since I am only using my 450 on my property and during the winter, just clearing snow away on the gravel roads, I decided I could get by for the winter using just the one clutch. This should relax the clutch plates and just maybe, seperate the rusting ones that I am sure I have. I am also using the suggestion of JD, I am keeping the two levers pulled back (with a thick bungee cord) while the machine is not in use. I am hoping that this clutch might free up with use. I re-assembled everything to try the machine and one clutch still does not work properly. I also found that one pad had pulled off the brake band (they are bonded on). I could tap it out with a aluminum drift and hammer, but it only moves maybe 1/8", I guess enough to loosen the clutch plates. I also found one clutch that would stick when the lever was pulled - ie the clutch drump would not move. This took a little while and now the shaft and foot brake are both free. Squirted oil in and used compressed air to force the oil through the bearing bushes until I could see it exit around the shaft - then used the vice grips. First I drilled two small holes in the bosses that hold this shaft. I was able to free the foot brake shaft up by using a pair of vice grips and working them them back and forth. I recently went through this on my machine.In my case I lifted off the seat and tank so that I could remover the large cover plate over the clutch compartment.
