So, right now I have put out the boggie, rebuilt it and fixed it all over. I will also change the track to a 144", so I have to lift out the drive axle.

How do I get out the drive axle?

My sled is a Venture 700 1998, with reverse gear.

My 97 Vmax 700 doesn't have reverse but the process should be the same. You need to remove the speedometer and bearing on the clutch side first, the bearing has two allen head set screws on the side then you can pull it off the shaft. Next you need to open the chain case, remove the chain and sprockets as well as the reverse gear. With enough fiddling you can remove the axle without removing the entire chain case but I found it easier to just remove the whole thing since it was held on with a couple of bolts and made removing the axle a breeze. Don't forget new gear oil to refill the chain case after re-installation and check the chain tensioner to make sure it's still good.
 
If you don't have the service manual, you can get an exploded view of the chaincase from any internet oem parts dealers website. Print a copy of the parts fische to have in the garage. When you take the parts out lay them out on a big piece of cardboard in the order that you remove them. Then it's easy to put it back together in the reverse order. Just take your time and take pics along the way. Mine wasn't nearly as bad as I thought it would be. Gil
 
Another thing. I replaced the seals and o rings well as the bearings in the backside of the chaincase while I was there. I knew my luck and I didn't want any leaks or to have to do it again because of a bearing I could have replaced when I was in there. Gil
 
Thanks a lot.

I heard from someone that the chain case doesn't need to be opened, just moved from the bolts so the drive shaft could get out from it.

Anyone who knows the right answer of that question?
 
I just went thru the same thing on mine. There is a bolt that holds the lower gears on the axle, you need to take out anyway. I personally went ahead and removed everything to clean and inspect it while I was in there. I also went ahead and removed the inner case and changed the bearings, seals and o rings. The last thing you want to do is put it all back together and have a leak or discover a bad bearing and have to do it all again. If you have luck like mine that's exactly what would happen, lol.

I learned last year, the hard way. When u have it apart, if u not replacing the bearings or seals, at least shoot some greasebetween the bearing & seal from the backside, before you put it on the shaft. I never paid much attention, but always thought the chaincase bearings were being lubed by the c-case lube. NOT true. The bearing is sealed on the chain side, open on the back, between the seal. I have had mine apart many times, (new tracks, 8 tooth drivers) but never realized the bearing was NOT being lubed. until the lower bearing went out last year out on the trail. Grease them from the backside before assembly.
