When messing with mine a few months back I do remember one or a couple gears that stayed out and didn’t come off.. not sure if your suppose to take apart or not tho
It’s for a 22 but I’m pretty sure it’s that sameI have the maintenance manual if you need it I can send it to you at your email just message me
Ended up repairing it, 2nd gear does need to be pressed off. My 20 ton struggled with it too.It’s for a 22 but I’m pretty sure it’s that same
