Safe Shop Tools Inc is reintroducing the PakPress tool, a hand-held, hydraulic device that allows truck, trailer, and bus technicians to remove and install studs without removing outboard hubs. New adapters are available to remove and install ArvinMeritor (formerly Rockwell) air disc brake double-ended studs on severe-duty vehicles. For a typical 10-stud outboard hub, the job is reduced from two hours to less than 30 minutes.
With the PakPress, technicians not only avoid removing and cleaning the hub, but also avoid replacing seals - and possibly damaging bearings.
The design includes a pump that accepts a standard air hose and sends 10 tons of pressure to a hydraulic ram inside a cast steel frame. The PakPress tool pushes on the threaded end of the stud, smoothly squeezing it out. The tool pushes new studs in by their heads to install them. A set of five fitting tools helps remove or install studs, or extract broken studs. For full details, contact Safe Shop, PO Box 4206, Missoula MT 59806.
