This program focuses on processes and conditions that result in a contamination-free component for the end customer. The program covers certain areas such as minimizing sources of contamination, contamination control awareness and training programs, equipment and processes to clean parts and cleanliness of fluids used during assembly and testing. OEM’s “5-star” rating, the highest rating given to a facility or dealer, signifies OEM’s commitment to continual improvement in quality as well as reinforcing OEM as a world class remanufacturing facility.

Disassembly

All components that flow through the OEM facilities lean design have a standard bill of materials for a given part as well as any technical documents required including service letter information to ensure all components remanufactured at OEM contain the latest updates for parts and/or salvage operations.

OEM's comprehensive 70,000 square foot machine shop can accommodate all machining work that may be required for the remanufacture of a component.

Equipment includes:

  • Vertical and horizontal lathes
  • A crankshaft grinder that can accommodate shafts of up to 22 feet
  • Computer-controlled Rottler machines for repairing connecting rods
  • Milling equipment that can handle wheel groups to 8 feet in diameter, up to 6 feet in height and 33,000 lbs.

In addition to the our machine shop, OEM also has state-of-the-art

  • Shot peening for parts up to 20 feet long and 32" diameter
  • Chrome plating in eight horizontal and vertical tanks
  • Spray and general welding

Inspection

During this phase of the process, all parts are subjected to inspection to determine if the part can be reused, salvaged or replaced. The necessary measuring devices to ensure tolerances are within the manufacturer's reusability guidelines is essential in determining whether a part can be reused, salvaged or replaced with new. As well, OEM extensive quality assurance program draws on non-destructive testing using techniques such as liquid dye penetrant (LPI), wet and dry magnetic particle testing (MPI), ultrasonic testing (UT), as well as air and water pressure testing.

Assembly &
Testing

All components are assembled by product specific technicians who are organized into specialized employee teams. The allows the technicians to focus on specific processes. OEM has developed a pool of talented experts who consistently product top quality components.

OEM utilizes world class engine and powertrain testing facilities including:

  • Two computer controlled engine dynomometers (2,750 hp and 7,000 hp) with the larger bench designed to fully test the 797 Caterpillar 3524 engine module.
  • Two computer controlled powertrain test benches (500 hp and 700 hp) with the larger specifically designed to test the Caterpillar 797 transmission and torque converter.

In the engine and powertrain testing process, technicians run all engines at full horsepower to reflect actual, rather than simulated, operating conditions. All benches are computer-controlled so technicians are unable to intervene and provide manual passes.
