Inside a D7R rebuild

The best way to understand the value and benefits of the Cat^® Certified Rebuild process is to go inside an actual machine rebuild. Read on for details of how one Cat dealer recently transformed an 11,300-hour D7R into a zero-hour dozer featuring a new machine warranty.

Major Components

The Cat Certified Rebuild process touches every major system and component on a machine. That's how we're able to restore its original performance and productivity levels. Here's a look at the reconditioning work, engineering updates and performance testing applied to the D7R rebuild.

Engine

The rebuilt D7R's engine was upgraded to like-new performance and emissions standards and reconditioned with approximately 1,000 new and Cat Reman parts — then tested to ensure its quality, power and performance met owner expectations.

Transmission

The dozer's transmission was rebuilt and upgraded to like-new condition, with components replaced with genuine Cat parts — renewing the performance of the entire power train.

Final Drive

Engineering upgrades, along with renewed protection against contaminants and debris, enhance the rebuilt D7R's final drive performance. Fast-wearing parts like bearings, gaskets and seals were replaced with new parts.

Differential Steering

The Cat Certified Rebuild process restored the dozer's load capacity, power and speed control. The differential steering system was also equipped with the latest maneuverability enhancements.

Precision edge cutting blade

A key part of the D7R's rebuild was restoring life for worn cutting blades. The option to flip the edge helps ensure durability through multiple wear cycles.

Undercarriage

The dozer's track group life was extended, and rotating and replacing worn parts helped balance undercarriage wear. Both contribute to improved performance and increased operator comfort.

There's no better time to rebuild

Bringing your Cat machine back to like-new condition for a fraction of the cost of buying new is a great deal. What makes it even better? Special offers available for a limited time only!

Upgrades and enhancements

Every Cat Certified Rebuild includes the option to upgrade optional features and technologies to current standards. It's an affordable way to enhance your machine even further while it's already in the shop for a rebuild — no additional downtime required. Take a closer look at the upgrades and enhancements added during the D7R rebuild.

Folding access ladder kit

Ease of maintenance was a priority for this dozer rebuild, so the owner chose to add a folding access ladder kit, providing service personnel with quicker, simpler access to the fuel tank.

Track Spade and Holder Kit

Another serviceability upgrade on the rebuilt D7R was the addition of a track spade and holder kit, which allows for faster, easier undercarriage cleaning.

LED Work Lights Package

Upgrading the rebuilt dozer with LED work lights helps illuminate the surrounding area. That improves operating visibility, increases jobsite safety and adds productive work hours to the day.

Work area vision system (WAVS)

The addition of WAVS on the rebuilt D7R also helps to enhance safety. Robust, closed-circuit cameras and an in-cab display combine to increase operator awareness of the work area.

Upgraded bluetooth radio

Upgrading the D7R's standard radio to a heavy-duty receiver equipped with Bluetooth technology isn't just a perk for operators — it also helps ensure they can stay connected even in rugged conditions and extreme environments.

PL542 Product Link™ with VisionLink® subscription

The rebuilt D7R now features Product Link™ hardware to collect and transmit machine data and includes a VisionLink^® subscription that enables the owner to access custom data insights and reports on everything from dozer location and utilization to health and performance.

Your dealer is standing by

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 Rebuild performed by your local Cat dealer.
