I have a few questions on drive sprockets for scorpions. I got my 440 running, but one of the drive sprockets is about gone. If I cannot find a good replacement drive sprocket, is there a way to make a common- easy to find drive sprocket work on my scorpion? How hard is it to replace the drive sprocket? I assume it will take a few hours to do, and is there any special tools needed to do the job. Thanks all for the help.

Shouldn't be a problem finding a replacement drive sprocket. A bigger job than you might think. Probably take you a couple of weekends if you have never done it before. Sorry! No special tools needed, only common sense and plenty of patience! Buy the new bearings before you start the job and try to understand how they lock onto the shaft. If you can't visualize how they lock onto the shaft you may have a problem doing the job. The lock-on bearings work on a "cam" principle. They are a standard type bearing that have a locking feature that has been used on industrial equipment for about 100 years. Not invented just for snowmobiles! Ask any farm implement mechanic how they work...he will know. They are used on all kinds of farm equipment! Good luck

Thanks a ton for the information. Glad to hear that it is doable, even if it does take a lot of time. Any idea what the part number is for the bearings and how to get them? I am hoping to source the drive sprockets from a used sled. Is there any way to judge how good the sprockets are, other than visual inspection? I would hate to go to all this trouble only to have them fall apart on me. Again, really appreciate the help and I hope you don't mind if I ask a few more questions as I tear into this project!
I found bearings from an electrical motor and industral supply company, they are the 1 7/8" shaft bearing I used in my 75 Whip, the brand is an AMI Bearings Inc. #KH206-18. Hope this will help you out. Carl
