Abstract: A positioning tool for repositioning adjacent objects in mutually spaced, coplanar relation, such as the ends of a so-called endless belt or chain, is used to facilitate their coupling/uncoupling. The tool has a fixed head portion for attachment to one end of the belt or chain, and a travelling portion for attachment to the other end that is to be repositioned, with parallel links to maintain the fixed and the travelling heads parallel. The gripping heads may be replaceable. A threaded jacking bolt connects the fixed and moving tool portions and applies the required jacking force. For rubber belts the attaching claws are inclined at about 22 degrees from the normal, to ensure grip and to avoid belt delamination. A range of tool widths and types may include provision for use as a wheel or pulley puller.
