Manco Carbide 7010 planetary gearbox removal
 

I'm new here. Been reading some threads on making my buggy faster. I am working on gearing but I can't figure out how to get the planetary gearbox off the rear jackshaft. I have taken the two jamb nuts off the shaft but the shaft will not pull through the planetary. So I'm wondering if I have to remove the jackshaft and remove the planetary. Any help would be appreciated.
