A sealed ball bearing needs to be pressed in because the tolerance of the external diameter of the outer bearing case and the inner diameter of the housing will be exactly the same so it's a size to size fit. It has to be this way so that the bearing remains secured with the heat transfer that takes place during the expansion of the bearing. However, it can be done manually but you need a piece of steel that fits on the outer casing and tap the bearing in lightly with a heavy mallet at various points to make sure that it goes in vertically. You have to keep pausing and inspecting the bearing to see if it starts to tip which is hard to rectify if it goes wrong so it's important to keep it straight. When the bearing is fully pressed in you will hear a difference in the sound. With a press operation, the bearing is guaranteed to be pressed in vertically all the way so there would be no issues with the bearing tipping at any point during the process.

Have you managed to source replacement bearings the right size? When I went to do this I found Caddy had used their own unique axle size, so I contacted Towsure and they supply an entire new axle with bearings for about £65, easy job to replace.
