By loader shaft I assume you mean hydraulic pump drive shaft. That can be replaced without removing the front axle. If you have one of the older style drives you may find it worth your while to replace the crankshaft pulley and hub which does require removing the axle.
Reservoir capacity depends on the make and model of the loader.
