dryer not heating

i am sorry i dont know all the technical term but here it goes, first I turned of the electrical breaker to the dryer, I unpluged the dryer and disconnected the dryer hose to the outside of home, I removed front dryer panel, remove front of drum panel, removed belt and found it to be worn, removed drum, removed the wiring connected to the back panel that had heating element inside, removed the back panel, removed the heating element inside the back panel and then reassembled unit. I had question whether or not it would ever run again, but it is working fine. Thank you for your prompt attention with sending the parts. i dont know if there was a different way to solve this problem, but i felt if there was an expection plate on the side of the unit, it would be helpful.
