The puller supplied with the kit is used to pull all the gears/sprockets with the exception being the magnet which just slides up however my point is if you pry you may do damage to your casing (based on experience when my puller was striped i broke pieces off the casing.) Always use the included puller on your gears/sprockets other then this picture your whole tutorial is spot on and lots of good information for new hobbyists to MB
