Description:
Several examples of this device have turned up and are a frequent "whatsit" because their function is far from obvious. The bar is part of a kit that includes one or more cylindrical "pushers" with handles, each pusher matched to a particular cylinder diameter. The extracting bar is used to remove the old sleeve and a pusher is used to insert the new sleeve. The pushers have a step near the handle. The smaller diameter fits inside the new cylinder sleeve and then the lip of the step bears against the edge of the sleeve. The sleeve is pressed into the cylinder by hand. In cars of the 1930s and '40s with sleeved cylinders, replacing the sleeves was a maintenance item that had to be done every few years.
