M5X180CHB Hydraulic Swing Motor for SANY SY215

This high-precision rotary motor assembly (swing motor) has original part numbers and cross index numbers from Sany, including 60180836, 60180836R, and 60180837R. The core uses Kawasaki's M5X180CB and M5X180CHB-12A/M5X180CHB-10A pump types. This assembly is specially designed for SANY's main excavator, perfectly matching 21 ton core models such as SY215LC, SY215LC-8, and SY215LC-9. The product is optimized based on first principles for high-pressure fluid dynamics, ensuring absolute certainty in rotary starting and braking. The physical dimensions of the packaging are approximately 520mm × 390mm × 410mm, with an overall net weight of approximately 88kg. The original factory standard position is connected.

"Extreme cleaning and alignment: Noise reduction and dust removal treatment are required for the unpacking and installation environment. Before installation, the mating surface of the rotary reducer must be thoroughly cleaned to ensure precise and stress free meshing of the output gear. Tighten the bolts using a torque wrench strictly according to the specified torque for symmetrical cross tightening.

Forced oil injection (core avoidance pit): Do not connect the high-pressure oil pipe to the wrong drain pipe (Case Drain). Before starting the engine, it is necessary to fill the top of the swing motor housing with clean hydraulic oil through the bleed/fill port. It is strictly prohibited to start dry grinding, otherwise the internal rotating components will undergo physical erosion within 3 seconds of ignition.

No load micro motion transition: After the first ignition, control the upper body to perform a slow rotation micro motion at a small angle left and right for 10-15 minutes in an unloaded state, thoroughly exhaust the circuit air, and confirm the thermodynamic stability before gradually applying the working load."
