I could not even pull the tub completely off due to rust. I sprayed some break free solvent waited , no go. ( I actually pulled the whole machine off the floor trying
to release the inner basket.) I told the owner the shaft and inner bearing which comes pressed into the tub would have to be replaced. They are opting for a new machine.
BTW, the allen head bolt was tight when I checked it. I could have laid the machine on it's side and used a 2x4 and hammer on the shaft, but in this case i decided not to.
I recently worked on a similar Cabrio washer. The pump in the rear is easily accessible. Be ready for residual water flowing out. I found a dime in the pump and a sock ready to go in to it. The problem with this one was no spin. I ran the auto diagnostic and the tests, and eventually pulled the inner tub out and found gym trunks, a speedo swimsuit and coins in the bottom of the outer tub. They were stopping the spin when the water level was low. It isn't difficult to remove the inner tub.
