Drive Train

Cat® Backhoe Loader illustration with six components pinpointed for remanufacturingRemanufactured Drive Train | Remanufactured Transmissions

1. Final Drives - Cat® Reman Final Drive Groups come fully assembled and ready to install. Planet gears are 100% magnaflux tested for cracks. All bearings, seals, gaskets and O-rings are replaced with new Cat® partsDamaged splines, keyways, threads and other wear surfaces are restored to new-part specifications. Planetary shafts, bearing cups and bushings are frozen and pressed into place. And finally, all final drives are 100% tested.

2. Final Drive, Spindles, Hubs-Housings - Final drive hubs and housing cores are dye-checked for cracks. Splines are removed and worn surfaces are built back up using submerged arc welding or laser cladding for same-as-new durability. All surfaces are machined to new dimensions and tested with a mating gauge.

3. Torque Converters - Cat Reman Torque Converters include the latest engineering updates and design improvements and are 100% tested to factory specifications. All seals, cups and bearings are replaced. All parts that cannot be restored to like-new condition are replaced with new Cat parts.

4. Drive Shafts - Remanufactured drive lines are balanced with new spider bearings and tubes installed. State-of-the-art Cat Reman salvage technologies, strict reuse guidelines and unequalled quality control systems guarantee the precision and quality originally specified are fully preserved to help deliver a lifetime of performance and value.

5. Transmissions - Cat Reman Transmissions include the latest engineering updates and design improvements and are 100% tested to factory specifications. All seals, cups and bearings are replaced. All parts that cannot be restored to like-new condition are replaced with new parts. We check transmission clutch plates for flatness, then precisely grind both sides to original surface finish specs for like-new performance. After reassembly, transmissions undergo a multi-step test that includes a runthrough of all forward and reverse gears at low and high idle, setting of valve pressure, check for leaks and proper shift timing.

6. Brake Bands and Shoes - Brake band shoe cores are disassembled and then thoroughly cleaned and inspected for damage. Asbestos-free lining is bonded and riveted to add dependability. In addition, all rollers, bushings and band springs are replaced with new parts; and damaged hardware is replaced wherever required.

Additional Reman Highlights:

  • Air Dryer Cartridges - Same-as-new quality and warranty at a fraction of the cost and available off-the-shelf.
  • Axle Groups - Same-as-new quality and warranty at a fraction of the cost and available off-the-shelf.
  • Clutch Plates - Same-as-new quality and warranty at a fraction of the cost and available off-the-shelf.
  • Compactor Wheels - When the wrapper thickness is worn too far to allow another retip, a Reman compactor wheel can provide a cost effective replacement option. Cat Reman wheels are 100% rewrapped providing a service option that should provide at least two lives. The wheels are available in various tip configurations to support various conditions.
  • Powertrain Piece Parts - Reaction hubs for off-highway trucks, tractors and large wheel loaders; gear hubs for oval track-type vehicles, planetary carriers for off-highway trucks and wheel loaders, carriers for differential, differential housings, duo-cone seals, brake anchors and front brake groups.
  • Steering Clutch Brake Groups - All cores are completely disassembled, cleaned and inspected for damage. All seals, friction disks, races and bearings are replaced with new parts (as are other parts that cannot be restored to like-new condition) including hubs, shafts and carriers.
  • Wheel Groups - Same-as-new quality and warranty at a fraction of the cost and available off-the-shelf.
