Compatible Brand: Caterpillar

Part Number: 372-7057 (3727057)

Superseded / Interchange Numbers: 372-7057, 3727057

Part Name: Track-Type Tractor Blade Lift Cylinder Piston Assembly

Technical Specifications: Cylinder Bore Fitment: 140.00 mm / Stroke: 1,653.00 mm / Weight: ~7.1 kg / Hydraulic Cylinder Piston Assembly

Compatible Machinery: Caterpillar Mining Heavy Track-Type Tractors / Dozers (D10T2 series)

What It Does:

Serves as the internal piston assembly operating inside the blade lift hydraulic cylinders on Caterpillar D10T2 series large mining track-type tractors (dozers). Mounted onto the cylinder rod, it separates the cylinder barrel into two distinct hydraulic pressure chambers (extend and retract sides) and houses the dynamic piston seals, wear rings, and guide bands. It converts high-pressure hydraulic fluid forces into direct linear mechanical force to drive blade raising, lowering, and down-pressure operations.

Importance:

A critical internal drive component essential for maintaining peak hydraulic efficiency, blade down-pressure, and lifting capacity during demanding mining, ripping, and overburden removal. Precision-machined to match the 140.00 mm cylinder bore with a robust 7.1 kg high-strength structure, it withstands extreme hydraulic pressure spikes, dynamic shock pulses, and cyclic fatigue, while providing an optimal seating groove profile for internal seals to prevent fluid bypass and internal barrel wear under continuous heavy-duty operation.
