The impeller is held onto the auger drive shaft with roll pins. They cannot be knocked out whle in place. Even if you could the impeller will be rust mated to the shaft and impossible to slide off. There are also parts in back of the housing that have be taken off. The impeller, auger shaft with rakes and gearbox are usually taken out as an assembly.
The machine has to be split into two parts. There are 6 bolts on the bucket side of the tractor base that have to come out to seperate the bucket and tractor. That will give you access to the auger pulley on the tractor side of the intake housing.
With the pulley and it's key out the assembly will slide out of the auger support bearing mounted on the back of the bucket.
Most often the auger drive shaft will be rust frozen to the support pulley and take some effort to get it free. You can soak the bearing/shaft area with solvent.
Tip the bucket up on it's front supported by 2x4's on each bucket edge. Then bang the auger drive shaft to break the rust on the shaft/bearing area.
It helps to first file any rough spots by the key area and very back of the shaft as it may be oversize to the bearing hole. You can emery cloth off the rust there so it has a better chance of going through the bearing.
Tap the shaft with a board over the end of the shaft so you don't deform the back of the auger drive shaft.
