MSG‑27P and MSG‑44P hydraulic spare‑parts are high‑quality aftermarket replacement components for KYB swing piston motor, compatible with LSGMF27/10W and LSGMF44/10W‑R21 rotary motor assemblies, widely used on small‑and‑medium‑size excavators. This series includes core wearing parts: cylinder block, valve plate, piston shoe, retainer plate, ball guide, drive shaft, bearing and complete seal overhaul kits. Manufactured with high‑strength wear‑resistant alloy and ultra‑precision machining, these spare‑parts perfectly match original motor parameters, effectively solving swing‑motor failures such as slow rotation, insufficient torque, abnormal noise and hydraulic‑oil leakage.
Excellent Interchangeability: Strictly manufactured according to KYB MSG‑27P, MSG‑44P original specifications, perfectly fit for LSGMF27/10W and LSGMF44/10W‑R21 swing motor, directly replacing original spare‑parts without extra modification.
Superior Wear‑resistance: Premium alloy raw‑material withstands heavy‑load friction and high‑pressure impact during long‑hour construction‑site operation, greatly extending service‑life.
Stable Rotary‑Performance: High‑precision grinding and tight dimensional tolerance guarantee smooth rotation, low‑noise running and steady torque‑output under continuous‑working conditions.
Flexible Selection: Separate single loose‑parts and complete overhaul repair kits are available, to satisfy different maintenance‑and‑rebuilding demands.
Reliable Quality‑Control: Every batch of spare‑parts passes full‑performance inspection before shipment, low breakdown risk in harsh working‑scenarios
