The problematic compactor was a Kitchenaid KUCS03CTSS0. After manually raising the compactor platform by using a ratchet wrench on one of the three chain gear assemblies I found that a large nylon HELICAL gear broke in half. The original gear mast have been discontinued as I was unable to find any reference to it. All illustrations referencing the compactor showed a STRAIGHT SPUR gear. Searching APP I found a GE assembly (GCG1580LSS) that looked identical to my compactor (including the helical gear pn: AP4435807). The gear in the kit was a perfect fit and was exceptionally easy to install (20 min at most).
