Hi, my name is ***** ***** I will assist you with your query.
The belt is located at the bottom of the bread maker, I cant find your model's manual but page 23 of the manual here shows you the order items should fit.
There is also a video tutorial for an LG breadmaker you may find useful, it should be more than a 30 minute job to remove the underside, slip of the belt and put the new one on.
Please let me know how you got on, and if you need any further guidance.
The video is here.
