Drum Brake Shoe Retraction Tool

A hand-held tool retracts the photoconductor drum brake shoe while the drum shell is placed in position during assembly.

During manufacture, a spring normally holds the brake shoe in a position which interferes with the final placement of the photoconductor (PC) spindles. The tool is also used whenever a new photoconductor is installed. Without a tool, assembly is difficult because the final clearance leaves too little room for a finger. Common tools, such as screwdrivers, slip off the shoe and may damage the take-up gear.

The retraction tool shaft has a diameter small enough to clear the minimum shell-to-plate opening required for proper shoe retraction. A notch at the end of the shaft engages the brake shoe without slippage, and the shaft is angled to place the handle in a convenient position for the operator.
