4288036 4208638 4334448 Final Drive for Caterpillar 6015 6015B | Mining Excavator Travel Gearbox

The Final Drive Assembly (P/N 4288036, 4208638, 4334448, 4406947, 4304192) is the high-torque mechanical powerhouse designed for the Caterpillar 6015 and 6015B hydraulic mining shovels. Engineered for the 140-ton class, this multi-stage planetary gearbox translates massive hydraulic pressure into the unrelenting tractive effort required for heavy-duty overburden stripping and bulk excavation.

Unmatched Tractive Effort for the 140-Ton Class The Caterpillar 6015B is designed to move more material at a lower cost per ton. The 4288036 / 4208638 Final Drive is the critical component that makes this possible, providing the massive drawbar pull needed to navigate steep pit ramps and unstable floor conditions.

In a mining environment, a gearbox isn't just a part—it's a liability if it fails. Our premium units are engineered to withstand the extreme shock loads and thermal stresses of 24/7 operations. By utilizing induction-hardened gears and precision-ground sun shafts, this assembly minimizes internal friction and prevents the spalling that leads to catastrophic "metal glitter" in your gear oil.

The Cat 6015 series is a global workhorse, and our drive assemblies are optimized for these diverse environments:

• North America & Australia: Built to meet the rigorous "Uptime" demands of the Canadian Oil Sands and the Pilbara, where high-production cycles require maximum gearbox reliability.

• CIS Regions (Russia, Kazakhstan): Features "Arctic-Grade" housing metallurgy to maintain structural toughness and prevent cracking during high-torque cold starts in Siberian temperatures.

• South America (Chile, Peru): Engineered with high-altitude resilient seals to resist oil thinning and maintain lubrication integrity in deep-pit copper mines.

• Africa: Optimized with enhanced thermal dissipation properties to keep gear temperatures stable in high-ambient desert heat.

For an excavator of this scale, maintenance is your only insurance against downtime:

S.O.S. (Scheduled Oil Sampling): Regularly sample the gear oil for iron and copper content. Catching a bearing wear issue early can save the entire 4304192 planetary set from destruction.

• Magnetic Plug Inspection: Clean and inspect magnetic plugs at every service interval. While fine "fuzz" is normal, any distinct metal flakes indicate an internal gear or bearing is spalling.

• Case Drain Line Check: Before installing a new travel motor, ensure the case drain line is clear. A blockage here will blow the shaft seal of a new motor instantly.

• Floating Seal Vigilance: Any sign of oil weeping near the sprocket is an emergency. Once oil gets out, abrasive dirt gets in, and the countdown to failure begins.

Guangzhou Tieqi Construction Machinery Co., Ltd. (IRON CAVALRY) is strategically located in Guangzhou's Huangpu District, approximately an hour from Baiyun International Airport. We have been a dedicated specialist in engineering machinery hydraulics for nearly 15 years.
