Retrofit power door assembly

A sliding door assembly comprises a frame assembly, a sliding panel carrier, and a sliding panel mounted to the sliding panel carrier. The sliding panel carrier is mounted to the frame assembly for generally rectilinear movement to enable movement of the sliding panel between a closed position and an open position. The sliding panel carrier has a pivot pin receiving opening. A door controlling unit moves the sliding panel carrier in a generally rectilinear manner between the open and closed positions. The sliding panel has a mounting bracket mounted to the top rail thereof. The bracket includes a pivot pin that moves between extended and retracted positions. The sliding panel is mounted to the sliding panel carrier by inserting the pivot pin into the pivot pin receiving opening. As a result, the sliding panel can swing relative to the frame assembly through a breakout movement from a normal, non-breakout position to a breakout position. The bracket, the pivot pin, and the pivot pin receiving opening are constructed and arranged such that, when the sliding panel is moved in a swinging manner to the breakout position thereof, a load applied to the sliding panel that tends to pivot the sliding panel about a point spaced from the pivot pin creates a reaction force that is applied to the pivot pin and is transmitted to the sliding panel top rail through the bracket.
