Repair or Remanufacture

Kirby-Smith offers repairs or remanufactured components, including engines, transmissions, torque converters, hydraulic pumps, hydraulic cylinders, and drive motors. All remanufactured components meet OEM standards and carry a warranty that leads the industry.

Track Press Services

Heavy construction equipment is ruggedly made to withstand the demands of the job, but we know that there are wear items that are designed to be replaced to maintain the longevity of the machine as a whole.  Kirby-Smith Machinery can assist you in the tough job of replacing those worn track pads and shoes, as well as performing pin and bushing turns. We take pride in the durability and longevity of our track repair machines and our machines are engineered to perform and built to last.

Undercarriage Repair

Kirby-Smith can service any undercarriage brand. Our custom track services range from complete undercarriage replacement to link replacements, component removal and installations, track adjuster rebuild and replacement, and roller frame repairs and alignment.

Diagnostics

Our facilities are equipped with state-of-the-art diagnostic tools for total machine evaluations, including engines, drive trains, and hydraulic systems. Kirby-Smith’s shop staff is factory trained and able to pinpoint and correct problems quickly and cost effectively, to minimize your downtime.
“Kirby Smith's been outstanding and continue to do outstanding work. You have to have people that you can depend on to get you back into the game.”
