One New Aftermarket Replacement U-Packing for Komatsu Excavators
This U-packing is a hydraulic sealing component used in the track adjuster (idler tension) cylinder on Komatsu excavators. The 09370- prefix series in Komatsu's part numbering system designates U-packings specifically for idler cylinders, making this a precision-fit seal for track tensioning systems that maintain proper undercarriage tension and protect idlers from shock loads. Replace worn or leaking U-packings promptly to prevent track adjuster cylinder failure and uneven track wear.
