You will need SKF 6203-2RSH or similar:
Spec: 17mm 40mm 12mm 11000rpm single row radial ball bearing, with 2 seals.
Anything with those dimensions and specifications or better will work, i nearly used a fully water proof one.
Time needed: 10 minutes.
First remove the pulley (turn the bolt clockwise to undo).
Cut a notch into the pulley to allow you to get in at the snap ring and remove it.
Use small screwdriver and tap if need be to get it under the ring and pry it out, take care they will snap quite easily.
Place the pulley on an open vice or similar surface and using a drift drive the old bearing out, I used a large socket, gently tap it out, the pulley is cast and will fracture. If it does not want to budge then some penetrating oil may be needed.
Clean up pulley and press in new bearing, make sure that you push the bearing from the outer ring, if you push it on the seal or centre you will damage it, I found a large socket that was the perfect size. Gently push the bearing in.
Put a little grease onto the snap ring and push it back into place
