Default Modifying G4 transmission

Can't find out what info I need without actually buying a G4. What kind of bearing does it use for the larger cog pulley? Is it just a brass sleeve, roller bearing or ball bearing?

And would it be possible to remove the pulley from the stock shaft and use a longer 5/8 rod?

Planning on having a custom made 5/8 rod that passes through the stock G4 bearing.
