Idler wheel problem (solved)

W801 Magnavox Micromatic record player inside of a Magnavox Astro Sonic. For whatever reason the idler wheel won't stay in contact with the pulley. This is also the case when the turntable is in position. According to the manual, its the "Idler Arm Assembly" that's not keeping the wheel against the pulley. Am I missing a spring? Looking at the manual it doesn't appear that I am... Do I need to replace the idler wheel because its too worn? Any ideas?
