Basic Parameters & Introduction
This mining grade heavy-duty travel assembly (integrating high-voltage travel motor and main reducer) has core original part numbers including: 21N-60-34100 (travel motor/motor assembly), 21N-27-00130, 21N-27-00140, and 21N-27-00190. This assembly is specially designed for Komatsu's large mining excavators, perfectly matching the main 120 ton models such as PC1250-7 and PC1250-8. The product is based on first principles for ultra heavy load transmission and high-pressure fluid dynamics optimization, ensuring absolute certainty of walking drive under extreme impact conditions. The physical dimensions of the product packaging are approximately 1180mm × 1120mm × 1150mm, with an overall net weight of approximately 1450kg. The original factory standard position is precisely aligned.

Maintenance Tips
"Daily inspection (every 10 hours): Before starting each shift, it is mandatory to inspect the drive wheels, large-diameter floating oil seals, and motor pipe openings to identify any trace leakage hazards.

Oil change during running in period (250 hours of operation): After the new assembly has been running for 250 hours for the first time, it must be forcibly drained and the gearbox gear oil must be replaced to thoroughly remove the hard metal particles generated during the initial running in period.

Regular mandatory replacement (every 1000 hours): Heavy duty mining grade gear oil (such as SAE 85W-140) must be thoroughly replaced every 1000 hours of operation (or up to 1 year). In harsh mining or frequent crushing conditions, the cycle needs to be forcibly shortened by 50%."
20260612163804h0_69b003c52c91a259174eaec49cb8c133 (1)
Installation Tips
"Extreme cleaning and hydraulic fastening: Before lifting and docking, the installation surface of the track frame must be absolutely flat and free of any foreign objects. All high-strength fastening bolts must be coated with special anti seize compound and tightened in multiple stages and symmetrically with hydraulic or high torque wrenches strictly in accordance with the original factory's specified torque.

Motor forced oil filling (core avoidance pit): Do not connect the wrong drain pipe (Case Drain) when connecting high-pressure hydraulic pipelines. Before starting the engine, clean hydraulic oil must be filled from the oil injection port on the top of the travel motor housing. Dry grinding is strictly prohibited during start-up, otherwise the internal plunger will undergo irreversible physical erosion within 3 seconds of ignition.

Transition of aerial exhaust test: Use a working device to suspend the track on one side, control the walking mechanism to run slowly and alternately for 15-20 minutes, exhaust the air inside the circuit, closely monitor the gear meshing sound, and confirm the thermodynamic stability before gradually putting it into operation."
