Lawnmower Wheel Bearings Replacement

While cutting the lawn, one of the rear wheels on the mower simply fell off. The wheel bearings had collapsed. Once replacement bearings were sourced, the old bearing inner was tight on the axle, some WD40 and a vice grips persuaded it off. New bearings were pushed into the wheel, again the inner bearing needed some lubrication to get it on to the axle far enough to allow the wheel to be refitted. On with the locking nut and the mower is back in action.
