The Chief gun applies self-piercing rivets for maximum efficiency. This makes the Chief rivet gun easier to maneuver in tight spaces and move from one rivet to the next. Since there is no battery in its base, the rivet gun is significantly lighter than battery-operated models, which can weigh more than 10 lbs. To begin riveting, the technician simply connects the gun to the pressure intensifier via a hydraulic hose. This modular design allows the PNP90 gun to evolve with the industry. As new applications are developed, users will be able to upgrade the PNP90 gun with additional actuators. Quick-connect couplings provide a fast and easy connection to the rivet gun actuator or optional blind rivet actuator. The intensifier converts air pressure of 87 psi (6 bar) from a standard air compressor to 8,702 psi (600 bar) hydraulic pressure at the rivet gun tip. The PNP90 gun’s riveting power comes from a pneumatically-driven hydraulic pressure intensifier. This consistent performance helps technicians properly complete repairs in record time. By utilizing air and hydraulics, the Chief PNP90 gun is able to drive the last rivet of the day as hard and as fast as the first. While today’s battery-operated rivet guns may get the job done, their power drains throughout the course of the repair. The new PNP90 rivet gun features a pneumatic-hydraulic design that offers improved consistency over battery-operated riveting systems. Labor/Material Savings: Works in conjunction with the Steck Al Skin Zipper, P/N 21892 and Al Skin Zipper2, P/N 21896 allows the technician complete the door skin process and build his/her resume for aluminum repair.“Rivets offer an ideal solution for bonding two different metals together, and their place in the collision repair process will continue to grow as automakers increasingly mix aluminum with steel in new vehicle construction,” says Rob Elliott, lead engineer, collision and controls, for Chief parent company Vehicle Service Group (VSG). Replace the required SPRs and re-install trim panel according to manufacturer procedures.Install your 3/4” or 19 mm socket to your 1/2” impact wrench and engage, within 3-5 seconds you will see the bottom of the screw flush with the door flange.Insert the new SPR on the magnetic end of the hex bolt, hand-tighten to the flange area keeping the body of the SPR Insert tool against the door flange.Technician locates a spot on the flange area next the SPR you just removed to insert the replacement SPR after you have replaced the door skin or quarter panel.The Steck SPR Insertion Tool, P/N 21960, is a high-grade hardened steel frame with a 1/2” 20 Grade 8 hex bolt with magnetic end and center recess to hold the replacement SPR while inserting the SPR with a 3/4” or 19 mm socket on your 1/2” impact wrench.
