I've just stripped down my Hotpoint WF00P, needed a sledge hammer to remove the inner drum as one of the old bearings was such a tight fit! The one flush to the inner drum is a 30 mm but the other has a 25mm diameter and as a result won't slide on/off without significant effort. The spindle has a slight taper and this 25mm bearing just sits at the end (30 mm would leave a gap), I'm guessing providing it's own water tight seal. Any advice on the right replacement kit? Thanks.
