Newbie Question - Puncture / Shimano IG-3 removal+reassemby

SaddleBack

First timer on the forum, been back in the saddle for a fortnight after having not ridden in anger since I was a teenager, loving every minute of it.

Got a Globe San Francisco 2 with a Shimano IG-3 Internal 3 speed hub, and managed last night to tear the inner tube on the rear tyre round the valve with a combination of over-aggressive pumping and a possibly perished tube. If I can't repair the tube, and given the location of the rip I'm guessing not, then how easy is it to remove and reattach the rear wheel given all the gubbins attached to it? Guy at Evans tried to put me off, and I can't find any info anywhere on either the Specialized or Shimano sites, so I'm turning to you lot for help. Cheers in advance...

Saddleback, Its not too hard to sort this out at all. Firstly with an allen key remove the grey gear adjuster on the side of the wheel. As you do this you will see there is a small rod inside the axle of the wheel revealed. Retain this remembering which way it came out. Now all you do is remove the wheel via the nuts and repair your tube / tyre. Re fit the wheel tightening up appropriatley and re insert the rod. Next replace the grey gear adjuster keeping the cable straight and pushing it firmly back on to its original position tight against the frame. Now tighten it back up the allen key and spin the back wheel changing gear a couple of times to ensure its running smoothly. To ensure the gears change properly select 2nd and then via the barrel adjustment next to the gear adjuster rotate until the yellow stripe is between the lines in the window on top of the gear adjuster. Hope I have helped and not confused !
