Quality Control, Testing and Remanufacturing

Stringent criteria is imposed at PPR to insure a quality product. Every unit is 100% factory tested before it enjoys the PPR diamond label.

Pulleys, voltage regulators, gears and many other component parts are manufactured at PPR's state of the art facility. Additionally, many units are re-engineered to improve the original equipment design and performance. This unique capability of designing and manufacturing new parts enables PPR to provide consistent product availability.

Customers can be assured that when a starter or alternator is remanufactured by PPR, the performance will be as good or better than when it was new.

Alternators

All units performance tested for proper operation, high/low speed output and voltage cutoff. All patterns oscilloscope tested.

• All housings have mount surfaces and threads guaged & repaired as necessary
• Fans straightened or replaced as needed
• All pulleys painted, plated or dipped to inhibit corrosion
• Shafts and threads gauged and replaced as necessary
• Double sealed new or remanufactured bearings used throughout
• All bearing seats gauged and repaired as necessary
• Rotors are tested for amperage and insulation quality
• Stator is inspected for insulation quality, phase balance and rated output
• Voltage regulator tested for voltage cutoff and output functions, replaced as necessary
• New terminal hardware
• High temperature insulators installed where required
• New brushes throughout, springs gauged and replaced as necessary
• Rectifier load tested, repaired or replaced as necessary
• High capacity diodes and high temp solder used where required
• Slip ring guaged and repaired as necessary, all are machined, polished and checked for "run out"

Starters

All units performance tested for torque, current drain and engagement voltage. Current is oscilloscope tested.
