Part Name: Bucket Hydraulic Cylinder Group

Technical Specifications: Bore: 150.00 mm / Stroke: 1,151.00 mm / Weight: ~293 kg / Hydraulic Cylinder

Compatible Machinery: Caterpillar Hydraulic Excavators (324D, 324E, 325D L, 329D, 329E, 330D L, 336D, 336D2, 336E, 336F L, 340D2 L, 568 series)

What It Does:

Serves as the bucket hydraulic actuator controlling bucket curl and dump functions on Caterpillar 324, 325, 329, 330, 336, and 340 series hydraulic excavators. Powered by high-pressure hydraulic fluid, it extends and retracts to drive bucket digging, material loading, and dumping cycles.

Importance:

Essential for generating optimal bucket breakout force and maintaining smooth operational cycle speeds during heavy excavation, trenching, and earthmoving tasks. Featuring a massive 293 kg heavy-walled barrel and high-strength forged rod, it effectively absorbs dynamic shock loads and severe torsional stress, while advanced internal seals prevent fluid bypass under continuous heavy operation.
