6-Step Rebuild Process

Every engine that comes to our HHP Rebuild Center goes through a six-step process that ensures it performs ‘as good as new’ before being shipped to our customers.

Step 1

Tear down

Every core is disassembled down to the last nut and bolt using automatic equipment like pneumatic impact wrenches, turnover devices etc. The parts are sorted and unsalvageable parts are removed while salvageable parts are routed to cleaning.

Step 2


Components are individually cleaned using the latest automated non-abrasive cleaning methods which ensure zero damage to the metal while all debris in the engine is removed. This guarantees that every component meets quality standards for reuse in the process.

Step 3


Stringent quality assurance processes are followed to verify that the engine meets its original factory specifications. Each part is inspected using sophisticated systems. For example, magnetic particle inspection is used to detect cracks that are invisible to the naked eye. Any part that fails inspection will be scrapped.

Step 4


The out of specification parts are re-machined on precision equipment to eliminate human error, assuring consistent quality and dimensional accuracy with every part. Production tolerances are measured using electronic gauging to achieve unprecedented accuracy. All gauging on the shop floor is monitored in our sophisticated gauge and electronic lab ensuring precise calibration.

Step 5


The engine is re-assembled using new and ReCon parts on a computer controlled conveyor which uses sophisticated systems like nut runners, manipulators, etc. Critical wear parts such as pistons, rings, bearings, brushings, seals, filters and gaskets are replaced with new Genuine Cummins Parts. The engine is built on a first-of-it’s-kind rebuild assembly line overseen by factory-trained technicians with 150 thorough quality checks.

Step 6


Every engine goes through a series of rigorous quality tests which include testing of horsepower, torque and 25 other vital functions. The testing equipment at our rebuild center uses same technology and equipment that tests new Cummins engines. The engines are then coated with environment proofing and painted as per application or customer requirements.
