Reman and overhaul

Engines

Remanufactured to factory specifications

Choose multiple engine options to match the condition of your machine and your current situation. Critical engine upgrades are installed along with the new bearings, seals, gaskets, pistons, piston rings and O-rings. 

Transmissions 

Engineered for durability 

Get responsiveness, speed and durability with Komatsu’s unique transmission/torqueflow designs. Your Komatsu remanufactured transmission will perform “like-new” to meet your machine’s performance requirements. Seals, O-rings, bearings, and other critical components are replaced with new Komatsu parts. 

Power modules

Excellent powertrain performance

Built-to-deliver factory specification powertrain performance, this specialized remanufactured component will achieve the speed, braking and responsiveness requirements on your machine. Critical components like seals, O-rings and bearings are replaced with new Komatsu parts.

Final drives and differentials

Performance in your challenging conditions

Travel under the most challenging job site ground conditions with specialized remanufactured final drives and differentials that efficiently convert torque to traction. Seals, gaskets, bearings and O-rings are replaced with new Komatsu parts.

Hydraulic cylinders and components cylinders

Specialized cylinder remanufacturing

Exchange the complete cylinder assembly for a fast turn-around or choose to exchange the cylinder rod or cylinder barrel as an even lower cost alternative. Hydraulic cylinders are disassembled and fully inspected. Rods, barrels and cylinder assemblies are then remanufactured to current Komatsu specifications. All wear and sealing items are replaced with new parts.

Pumps and motors

Performance and reliability

Remanufactured and tested in a positive air-pressure and temperature-controlled, clean-room environment to meet strict cleanliness requirements. These specialized remanufactured pumps and motors perform at extremely tight engineering tolerances and high operating pressures that deliver performance and reliability equal to the original components.

Electronics

Like-new cards, panels, controllers, and electronic components

Produced under full laboratory conditions with sealed entry/exit doors, controlled air temperature and pressure, anti-static floors and workbenches. Robotic technology is utilized for circuit and component diagnosis and precision welding. The remanufactured electronic components are then tested on simulators which reproduce the functions of real Komatsu machines.
