Basic Parameters & Introduction
"This high-precision micro walking drive assembly (integrating high-voltage walking motor and reducer) has core universal models KTM03A/TM03A/GM03A, and is fully compatible with and replaces MAG-18VP-230 and MAG-18VP-350. This assembly is designed specifically for classic micro excavator systems, perfectly matching core models such as Hitachi EX35, ZX30CLR, EX30-2, and Fiat Hitachi FH35-2, FH22.2, etc. The product is strictly based on fluid mechanics and high-speed transmission design, ensuring absolute certainty of output torque under small tonnage. The physical dimensions of the packaging are approximately 380mm × 290mm × 310mm, with an overall net weight of approximately 32kg. The original factory standard position is connected.

Maintenance Tips
"Daily inspection (every 10 hours): Before starting work, it is mandatory to check the sealing of the walking motor pipe mouth and the floating oil seal to prevent slight leakage caused by mud and sand wear.

First oil change (100 hours of operation): After the new assembly has run in for 100 hours, the old oil in the gearbox must be forcibly drained and replaced with new gear oil, and metal debris must be removed.

Regular mandatory replacement (every 1000 hours): Thoroughly replace the high-quality gear oil (such as SAE 80W-90) in the gearbox every 1000 hours of operation (or up to 1 year), and synchronously replace the hydraulic return oil filter element. The cycle of water or mud conditions is forcibly halved."

Installation Tips
"Extreme cleaning and alignment: Before installation, the hydraulic pipeline joints must be thoroughly cleaned with specialized cleaning agents. When tightening bolts, the contact surface of the frame must be cleaned, and a torque wrench should be used to tighten them symmetrically and cross according to the specified torque.

Hard motor oil filling (core avoidance pit): When connecting the pipeline, do not reverse the high-pressure forward/backward oil pipe and the motor drain pipe (Case Drain). Before starting, clean hydraulic oil must be filled from the motor drain port to prevent irreversible physical erosion of the plunger due to dry wear at the moment of starting.

Aerial test transition: Under the unloaded state of the entire machine's track, control the walking mechanism to rotate alternately at low speed for 10-15 minutes, exhaust the circuit air, and confirm that the gearbox has no abnormal noise before landing to bear the operating load."
