So now that you have everything ready first thing is first. grab something like a small flat-head screwdriver.
Next looking at your seat-belt spindle there is a little plastic piece that feeds it into the spindle detach it from the spindle.
Next pull the seat-belt all the way out so that there is none left on the spindle.
Once you have done this the spindle should look like this:
Next insert the flat head into the pulley at the top of the rollbar. (What this will do is keep the fabric from reeling back up when you take your hands of the seat-belt.)
Next remove the bolt from the spindle and pull away from the rollbar then towards you. (be carefull you do not want to dislodge the screwdriver.)
After that grip the spindle so it cannot spin
push the seatbelt through the spindle.
(example 1)
(example 2)
Once you have done this there is a pin that keeps the belt in the spindle remove it.
IT IS EXTREMELY IMPORTANT YOU DO NOT LET GO OF THE SPINDLE. IF YOU DO IT WILL RETRACT AND WITHOUT THE BELT IT WILL SPIN ALL THE WAY AND YOU WILL HAVE TO FIGURE OUT HOW MANY TURNS IT TAKES TO GET IT BACK TO ITS ORIGINAL POSITION.
Once the pin is out you can now pull the seat-belt through the spindle
