I wasn't questioning the gear ratio John. I was just pointing out it has the more complicated gearbox design.
It doesn't have to be taken "that far apart".
Remove the pickup rollers and the 3 screws on the bottom that don't say "grease" and the whole bottom cover of the chassis comes off with the brake shoe detail.
So easy. Even a caveman like myself could do it.
It's actually a really nice design from a maintenance stand point ,if it weren't for the extra non serviceable gears.
