Idler Pulley replacement - Amana Washer

[SIZE=3]Hello, I am planning to replace the idler pulley assembly on my washer (per a service tech checking it out and solving the washer having a really high pitch noise when on). [/SIZE]

[SIZE=3]Anyway, does anyone have instructions on taking out the old and putting in the new?[/SIZE]

[SIZE=3]Thanks in advance,[/SIZE]
