Maintenance Tips
"Daily inspection (every 10 hours): Before starting work, conduct a mandatory inspection around the drive wheel, focusing on checking the floating oil seal of the base and the motor pipe mouth to prevent trace leakage caused by mud and sand wear.

First break in oil change (150 hours of operation): After the new assembly has been running for 150 hours, it must be forcibly drained and the gearbox gear oil must be replaced to thoroughly remove any hard metal particles remaining during the break in period.

Regular hard replacement (every 1000 hours): Heavy duty high-grade gear oil (such as SAE 80W-140 or 85W-140) must be thoroughly replaced every 1000 hours of operation (or up to 1 year). In harsh mining or high-frequency crushing conditions, the cycle needs to be forcibly shortened by 50%."
20260612162127h0_7ccf30751920253dde36c9345b662c0d (1)
Installation Tips
"Extreme cleaning and heavy-duty fastening: Before lifting and docking, the installation surface of the frame must be absolutely flat, free of rust or foreign objects. All high-strength fastening bolts must be coated with anti seize compound and tightened symmetrically and in stages using a high torque wrench in strict 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 the hydraulic pipeline. Before starting the engine, clean hydraulic oil must be filled from the oil injection port on the top of the walking 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 no-load test: With the track support in an unloaded state, control the single-sided walking mechanism to run alternately at low speed for 10-15 minutes, thoroughly exhaust the circuit air, and monitor the gear meshing sound. Only after confirming that the thermodynamic state is stable can the working load be gradually applied."
