Certified Powertrain Rebuilds

Cat® Certified Power Train Rebuilds

System Rebuild - Save up to 70% compared to buying a new machine

You can restore your machine’s power train so it’s like-new again with the Cat Certified Power Train Rebuild program. All powertrain components are completely disassembled and all critical engineering updates are included – so it feels like you have a brand new machine that’s ready to get the job done. After all, a Cat machine is built to be rebuilt.

Cat® Certified Power Train Rebuilds include:


So you’ve decided to save thousands and complete a Cat® Certified Power Train Rebuild. Great choice – but what does that actually mean? Let’s take a look at our 9-step process to get you a ‘like-new’ machine that’s ready to work.

Step 1: 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/fluid analysis service. Cat Certified Power Train Rebuilds include more than 200 tests and inspections.

Step 2: 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 and reman 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.

Step 3: Reconditioning

This phase of the process addresses equipment needs not typically included in an overhaul. Frames are examined and, if necessary, straightened, welded and reinforced. Worn linkage pins and shaft bearings are replaced. Hydraulic systems are returned to their original levels of performance, reliability and cleanliness. Electronic control modules and software are also replaced.

Step 4: Engineering Updates

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

Step 5: 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.

Step 6: Reassembly

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

Step 7: 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.

Step 8: 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.

Step 9: 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.
