M5X180CHB-12A-95A/260-169-RG14D20A6 Rotary speed reducer assembly

This heavy-duty high-precision rotary powertrain integrates Kawasaki's M5X180CHB-12A-95A/260-169 high-pressure motor. The core matching planetary rotary reducer models include RG14D20A6 and RG14D20A5, corresponding to the core original part number 11C0169. This assembly is specially designed for core tracked excavators ranging from 30 to 36 tons, serving as the absolute axis for 360 ° rotation and precise braking of the upper body. The product is based on first principles for multi-stage planetary transmission and high-pressure fluid dynamics optimization, ensuring absolute certainty of torque output under heavy load compound action. The physical dimensions of the product packaging are approximately 580mm × 580mm × 760mm, with an overall net weight of approximately 235kg. The original factory standard position is precisely aligned.

"Extreme cleaning and heavy-duty fastening: Before lifting and docking, thoroughly clean the installation surface of the frame and the large gear ring of the slewing support to ensure precise and stress free meshing of the output gear. All high-strength fastening bolts must be tightened symmetrically and in stages using torque wrenches strictly in accordance with the original factory standard torque.

Motor forced oil filling (core avoidance pit): Do not connect the wrong drain pipe (Case Drain) when connecting hydraulic pipelines. At the same time as adding gear oil to the standard line of the reducer, clean hydraulic oil must be filled from the oil inlet at the top of the rotary motor housing before starting the engine. Dry grinding and starting are strictly prohibited, otherwise the rotating components will undergo physical erosion within 3 seconds of ignition.

No load micro transition: After the first ignition, control the upper body to rotate slowly at small angles left and right alternately for 10-15 minutes in a no-load state, thoroughly exhaust the circuit air, and closely monitor the gear meshing sound. Only after confirming that the thermodynamic state is stable can full working load be applied."
