Cat® Certified Powertrain Plus Rebuild (CPT+)

The cpt+ program includes the benefits of the certified powertrain rebuild (cpt) plus the ability to add specific parts, systems, or components to further boost performance and reliability.


This rebuild option includes radiator, engine, transmission, torque converter, final drives, and differentials, as well as any additional systems or components not included in basic CPT (rebuild hydraulic pump, operator cab refresh, machine painting, etc.). Approximately 200 tests and inspections are performed by Toromont Cat certified technicians.

Replacement or reconditioning of approximately 3,000 parts. Critical engineering improvements and updates are incorporated and extended coverage options are available.

The Process

A process this extensive requires trained professionals, specialized equipment, stringent quality control and access to the latest technical information and is available only through a Cat Certified Powertrain Plus Rebuild performed by Toromont Cat certified technicians.

  • Inspection/Evaluation

    The specific needs of your power train are determined through a comprehensive evaluation, which includes fluid analysis, careful visual inspections and a review of maintenance/S·O·SSM analysis service. Cat Certified Power Train Rebuilds include more than 200 tests and inspections.

  • Disassembly

    Once we’ve figured out the best approach, your power train will be completely disassembled. All hoses, belts, seals, gaskets, bearings and wiring will be replaced with new parts. Remaining parts will be inspected and measured against our strict re-usability guidelines. Those that do not meet our high standards will either be replaced with new or Cat Reman parts, or reconditioned to meet guideline specifications. Cat Certified Power Train Rebuilds include automatic replacement of approximately 3,000 parts.

  • Reconditioning

    This phase of the process addresses equipment needs not typically included in an overhaul.

  • Engineering Updates

    During reassembly, critical improvements that have been made to this machine model since original manufacturing will be incorporated into your power train.

  • Power Train Tests

    The engine, fuel system, transmission, torque converter, differential, final drives and radiators are also disassembled, inspected, reconditioned and updated with new or qualified parts. Then, before re-installation, each component is thoroughly bench tested.

  • Reassembly

    All critical torques, clearances and pressure settings will be maintained and recorded during careful reassembly of your power train by our professional technicians. Engine wire harnesses are always replaced.

  • Performance Testing

    Quality control is integral to the Cat Power Train rebuild program. Therefore, rigorous testing is conducted at several stages. Tests routinely preformed are: turbocharger boost, throttle response, stall speed rpm, transmission and steering clutch response. Instrument and operational testing are also conducted to ensure field performance levels match those in the shop.

  • Repainting

    Your machine will perform like new - and look like new - after a complete paint job and application of new Cat Certified Power Train Rebuild decal.

  • Customer Evaluation

    The rebuild process is not considered complete until your operators are satisfied with the performance of the machine or power train in its working environment.


Rebuild process

The rebuild process extends beyond a piece of rebuilt equipment. The value of your equipment increases with warranties and coverage from Caterpillar—and the support of the largest dealer and part distribution network in the world.

Choice of coverage

Every Cat Certified Powertrain Rebuild includes a new parts warranty on all replaced parts, and you can add more options for additional protection and peace of mind.
