help f&p ed56u dryer assembly problem?

I have an ED56 F&P dryer . I have it apart atm , and have replaced the heating element . but something is not right when I put it back together . the 2 pulleys arent sitting close to the shaft of the motor , which the belt runs through . I need to find a website that shoes me some internal , rear view diagrams/photos so I can see where I have gone wrong , Any assistance/info would be appreciated . Thanks Aleisha
