I opted to take advantage of this miserable stretch of wet Ontario weather to change the track on one of my silver bullets. Generally, everything is coming apart well but I was hoping to get the drive axle out without removing the chain case. The chain is out, mag side bearing cup is released, seals are pulled etc. I was hoping the axle could slide out of the chain case but I can't achieve any lateral movement. Perhaps I was deluded? Before I go to the next step and pull the chain case I thought I'd ask and see if there's any tip or trick I'm not aware of. In theory it looks like it should all slide over enough to drop the axle while leaving the chain case in place. Am now concerned that even if the chain case is released from the tunnel, the bearing may be so snug inside it that it will not readily release from the chain case. Any insight will be much appreciated. Thanks

I think you might have to loosen the case a little to allow the axle enough angle to get out. I think that an earlier sled with a much more narrow case you might be able to get away with it. But not likely with yours. That being said, make sure you have the rear axle entirely out to relieve all the stress of the track fighting you on getting the front axle out.
At the same time its not that bad loosening the inner case. Start with the front guide thing that has the pin up front. Don't adjust it, because that will ensure you get the case position right again afterwards. Then just loosen the bolts holding the case on. The only possibly tricky one will be the one that goes into the gas tank area. It originally had a nut that was held in place with little square thing, and it should hopefully still be in place. That way you don't have to hold it while removing the bolt. If it doesn't hold the nut still then you have to take the tank out to deal with it.
Hope that all makes sense.

Thanks for the tips and encouragement. I was able to get the axle out but I had to completely remove the chain case to do so. In the end I lucked out, everything came apart as it should. The captured nut in the fuel tank cavity stayed in place and didn't spin out so I didn't have to remove the muffler and fuel tank. Now I'm on the hunt for a rear axle. Whoever changed the rear sprockets in the past actually welded the nuts to the tip of the little bolts. There's no way those flange plates are coming off to release the brittle sprockets!
