Everything can be done by hand. The tires are very heavy and to pull the drums includes removing the hubs as well as they are an integral part. They are heavy as well but not impossible to handle. I think the popcorn icons were because most people who ask simple questions are somewhat over their head. I pull all 6 of my drums annually as it is a basic but needed task. I clean and repack the bearings, check the brake lining thickness, look for any trouble in the wedge brake or "spider" assembly, re-assemble and keep trucking. I sometimes long for the M35A2 days but then I drive my M923 to the posted speed limit and it sounds somewhat calm and happy. My old Deuce sounds very stressed to do 55 mph on 11R20 tires. Message me if you have any questions but I talk faster than I type.
