Excavator accessories E306e T7t2 final drive gearbox travel motor assembly

This high-precision compact driving device assembly (integrating high-pressure walking motor and planetary gearbox) adopts the industry classic T7T2 ton high-pressure high torque walking pump motor series as its core. This Final Drive Gearbox is specially designed for Caterpillar's core star models, perfectly matching 6-ton main star models such as CAT 306E and 306E2. The product is based on first principles to optimize high-power density fluid mechanics and planetary gear integrated transmission, deeply bearing the impact of small excavations under frequent directional operations in municipal and earthwork, ensuring absolute certainty of propulsion torque. The physical dimensions of the product packaging are approximately 420mm × 330mm × 350mm, with an overall net weight of approximately 52kg. The original factory standard position seamlessly connects.

"Extreme cleaning and torque alignment: Before installation, the frame and drive wheel mounting flange must be thoroughly cleaned to prevent micron sized gravel. All high-strength fastening bolts must be tightened using torque wrenches, strictly following the original factory standard torque for symmetrical and phased cross tightening to avoid local abnormal shear stress.

Motor forced oil filling (core avoidance pit): Do not connect the drain pipe (Case Drain) incorrectly when connecting the hydraulic pipeline. Before starting the engine, clean hydraulic oil must be filled from the air release/oil injection port on the top of the walking motor housing. Dry grinding is strictly prohibited for starting, otherwise the internal plunger will undergo irreversible physical erosion within 3 seconds of ignition.

No load micro exhaust transition: Use a working device to suspend the entire machine on one side of the track, control the motor to run at low speed with alternating micro movements for 10-15 minutes, thoroughly exhaust the circuit air, and closely monitor the gear meshing sound. Only after confirming the thermodynamic state is stable can the working load be applied on the ground."
