    ITR Gears:

    ITR Gears are Designed and Manufactured to cover a wide range of Drive Train applications for use on Caterpillar Dozers, Loaders, Graders, Trucks, and other applications. Tested and verified for material durability, dimensional accuracy, and precision during ITR Gearsmanufacturing, these high quality Gears are engineered to provide a Perfect fit, Excellent Field Performance, Endurance, Durability, and Reduced Noise in severe working conditions.

    ITR Gears are available for use on Final Drive, Drive Train, Ring / Pinions, Transmissions, Planetary Drives, Torque Converters, Engines, Pumps and Drives, Steering, Grader Blade Rings,Tandem Doves, and more.

    ITR GearsITR Manufactured Gears are designed, and precision manufactured to deliver reliable performance, increased wear resistance, and long life. ITR's Tooth profile Grinding, Shaving, and Heat treating procedures exceed industry standards and result in the highest component quality.

    Final Drive Gears and Pinions:

    ITR Crowned Gear Tooth ITR GearsProfiles prevent excessive point loading of teeth resulting from mating gear misalignment and also reduce pitting of gear surfaces. Special Heat Treating along with Induction Hardening ensures proper surface and core hardness to resist abrasion, impact loading, case crushing, tooth breakage, and pitting.

    ITR Track Chains


    Call (828) 649-7190 for a quote.


    ITR undercarriage components work together with our chains to provide excellent durability and long service life in the most demanding applications. ITR engineered chain designs contribute to maximize sealability and provide excellent field performance.

    Track Chain

    Sealed & Lubricated Chains for Crawler Tractors & Loaders

    Sealed and lubricated joints keep abrasives out of the pin and bushing area minimizing internal wear and reducing chain stretch. The result is extended undercarriage life and lower operating costs.

    Sealed & Greased Excavator Chains

    Sealed & Greased Excavator chains decrease internal friction and reduce chain noise. ITR Tracks are engineered to perform well in very tough working conditions. Track Chains incorporate Boron Steel Forgings, Polyurethane "dish" seals, Extreme Pressure Synthetic Grease and "T" style master pins for ease of installation, all of which contribute to strength and long service life.

    Undercarriage Components

    Track Chain Components

    Individual components work together to provide assemblies with Excellent Durability and Long Service Life in tough working environments.

    Pins & Bushings

    ITR Pins & Bushings are designed, manufactured, and dimensionally matched to link bores providing excellent pin retention and Track Joint Stability. Better joint reliability helps eliminate seal / joint problems and results in extended wear and performance.

    ITR Pins resist bending and breakage by using selected materials and special heat treating processes with differential spray quenching. ITR Bushings have high surface and core hardness that provides excellent strength and wear characteristics by utilizing Through Hardening or Through Hardening plus Induction Hardening processes depending on application.


    Forged Boron Steel links provide greater strength, stability and wear resistance. Sophisticated heat-treating processes give ITR chain links excellent surface hardness, deep hardening depth and strong core hardness for durability and strength.

    High strength materials in conjunction with heavy cross sections are designed to maximize pin to link contact area…Large pin to rail contact helps eliminate “Pin Walking” and premature failure in tough working environments. ITR link designs result in a link profiles that resist link twisting and deformation.

    ITR track chains use the preferred Split Master Link designs, produced using state of the art machining technology for proper mating of the split link halves.


    To keep lubricants in and abrasives out, ITR chain designs utilize specially engineered Rigid Polyurethane Seal designs. These durable long lasting seals combine high wear resistance and lubricant protection to extend pin and bushing life.

    Sealed & Lubricated joints on lubricated tracks are designed for the life of the chain. Advanced computer controlled assembly insures proper seal installation and guarantee each joint is filled with the correct amount of lubricant. Each lubricated joint is pressure tested during the manufacturing process. Wet joint Integrity is covered by ITR’s Wet Turn Assurance Warranty.
