I actually bought one of those from Buggymaster! it's been a few years though and it got stole shortly there after. I didn't have to remove or replace the jackshaft- they usually have a snap ring on the bearing case to keep in the right position in the tube or the bearing has a flange that rests against an inner tubing. I'd check that first as they don't usually press them in. What's on the other end?
