KOMATSU PC500 PC500-10 PC500LC EXCAVATORS FINAL DRIVE ASSEMBLY 2A8-27-00110 FINAL DRIVE MOTOR HIGH QUALITY TRAVEL MOTOR CONSTRUCTION MACHINERY

This mining heavy-duty high-precision travel device assembly (integrating high-voltage travel motor and planetary reduction gearbox), with original core part number 2A8-27-00110 from Komatsu. This top-level Final Drive Assembly is specially customized for Komatsu's large hydraulic excavators, perfectly matching core mining star models such as PC500, PC500-10, and PC500LC in the 50 ton industry. The product is based on first principles for integrated optimization of fluid dynamics high-pressure plunger and heavy-duty multi-stage planetary gear system, seamlessly carrying the complex alternating loads caused by high-frequency steering under harsh mining conditions, ensuring absolute certainty of propulsion torque. The physical dimensions of the product packaging are approximately 810mm × 680mm × 710mm, with an overall net weight of approximately 465kg. The original factory standard hole positions are precisely aligned.

"Extreme cleaning and torque tightening: Before using heavy-duty lifting equipment for docking, the installation surface of the trolley frame base and the drive wheel flange must be absolutely flat and free of any foreign objects. All high-strength fastening bolts must be tightened using torque wrenches, strictly following the factory's specified torque for symmetrical and phased cross tightening, to prevent slight deformation of the shell due to local stress concentration.

Motor forced oil filling (core avoidance pit): When connecting hydraulic pipelines, they must be absolutely aligned and do not connect the wrong drain pipe (Case Drain). Before starting the engine, it is necessary to fill the top of the walking motor housing with clean hydraulic oil through the air release/oil injection port. Dry grinding is strictly prohibited for starting, otherwise the internal rotating components will undergo irreversible physical erosion within 3 seconds of ignition.

Idle micro exhaust transition: Use a working device to suspend the entire machine's single-sided track support, control the walking mechanism to run slowly and alternately in front and back micro motion for 10-15 minutes, thoroughly exhaust the air inside the circuit, and closely monitor the gear meshing sound. Only after confirming the thermodynamic state is stable can the working load be applied on the ground."
