CAT E70 307 308 Final Drive Travel Motor 096 6836 102 6947 | Utility Excavator Gearbox

The Final Drive and Travel Motor Assembly for the Caterpillar E70 and 300-Series (307, 308) is the high-performance propulsion core for CAT’s legendary utility excavator line. Engineered for the 7 to 8-ton machine class, this assembly integrates a compact, high-torque hydraulic motor with a precision planetary reduction gearbox. Whether you are running a classic E70B or a modern 308C, this unit is designed to restore the nimble tracking and "grade-climbing" power required for urban utility, landscaping, and residential construction.

Restoring Precision Tracking for Tight Job Sites The CAT 307 and 308 series are the go-to machines for contractors who need big power in small spaces. Their ability to counter-rotate in soft soil and climb trailer ramps with ease depends entirely on the volumetric efficiency of the final drive. If your machine is "veering" to one side or feels sluggish during travel, your 096 6836 or 102 6947 motor is likely losing pressure internally.

Our premium replacement units are manufactured to match the strict hydraulic tolerances of Caterpillar’s utility line. Built with induction-hardened gears and high-load bearings, these drives ensure your tracks stay synchronized. Replacing a worn-out unit doesn't just stop a leak; it restores the "factory-fresh" tractive effort needed for aggressive site positioning and backfilling.

• North America & Europe: Built for the Rental and Utility sectors. These drives are fully compatible with modern high-pressure systems and meet the durability standards required for high-frequency urban road work.

• Southeast Asia & Oceania: Features reinforced mechanical floating seals to prevent the ingress of abrasive sandy soils and tropical mud, which are notorious for destroying small-class gearbox seals.

• South America & Africa: Engineered with metallurgical properties that resist structural fatigue in high-ambient heat, ensuring consistent torque delivery during long transport distances across job sites.

• Seamless 2-Speed Integration: Fully compatible with CAT’s automatic high/low speed shifting, allowing for fast site transit and high-torque performance when pushing.

• Forged Steel Gearbox Housing: Unlike standard cast versions, our housings are forged from high-strength alloy steel to prevent structural cracks under the heavy radial loads of an 8-ton machine.

• Integrated Parking Brake: Features a heavy-duty, spring-applied, hydraulic-release braking system for maximum safety on inclines.

• Direct "Plug-and-Play" Fitment: All hydraulic port locations (Main A/B, Case Drain, and Pilot) match the original CAT piping layout for a fast, hassle-free installation.

• The "Silent Killer" (Case Drain Pressure): Utility-class machines like the 307 generate significant return flow. Before installing a new motor, verify the case drain line is clear. A blockage here will blow the shaft seal of your new 102 6947 motor instantly.

• Gear Oil Management: Change the planetary gear oil every 500 operating hours. If the oil appears "milky," water has breached the seals; if it looks "metallic," your gears are spalling. Catch it early to save the gearbox.

• Sprocket Bolt Security: Due to the vibrations inherent in 7-ton machines, sprocket bolts can work loose. Always use new Grade 10.9 bolts and a high-strength thread locker to prevent flange damage.

• System Priming: Never run a new travel motor "dry." Fill the motor case with clean hydraulic oil through the highest port before starting the engine to ensure instant lubrication.
