706-8J-01110 Travel Motor Assembly for Komatsu WA100-5

This high-precision travel motor assembly (hydraulic travel motor) has a core original part number of 706-8J-01110 (also written as 706-8j-01110). This assembly is specially designed for Komatsu's core construction machinery, perfectly matched with major models such as WA100-5, and serves as the core power source for the driving assembly of the main reducer motor. The product is optimized based on first principles for high-pressure fluid dynamics, ensuring absolute certainty of walking torque and driving force. The physical dimensions of the product packaging are approximately 420mm × 310mm × 330mm, with an overall net weight of approximately 48kg. The original factory standard position is connected, and the parameters are tightly fitted, allowing for seamless replacement.

"Extreme cleaning and alignment: Noise reduction and dust removal treatment are required for the unpacking and installation environment. All hydraulic pipeline joints must be thoroughly cleaned with specialized cleaning agents before connecting to a new motor, and foreign objects are strictly prohibited from entering the interior of the motor. The bolt connection needs to be tightened symmetrically with the specified torque.

Forced oil filling (core pit avoidance): After the motor and reducer assembly are docked and before starting the test, clean hydraulic oil must be filled from the case drain on the top of the travel motor. It is strictly prohibited to start dry grinding, otherwise the internal plunger and distribution plate will undergo physical erosion within 3 seconds of ignition.

Transition of no-load test: After starting, maintain the whole machine in a supported or unloaded state, control the walking mechanism to run alternately at low speed for 10-15 minutes, exhaust the circuit air and confirm the thermodynamic stability before gradually applying the working load."
