Part Name: Backhoe Swing Hydraulic Cylinder Group

Technical Specifications: Bore: 100.00 mm / Stroke: 254.00 mm / Weight: ~38 kg / Hydraulic Cylinder

Compatible Machinery: Caterpillar Backhoe Loaders (416F, 420F, 422E/F, 428E/F, 430F, 432E/F, 434E/F, 442E, 444E/F series)

What It Does:

Serves as the hydraulic actuator responsible for swinging the rear backhoe boom structure left and right horizontally on Caterpillar E and F series backhoe loaders. Operating within a dual-cylinder slewing assembly, it converts hydraulic fluid pressure into linear push-pull force to pivot the backhoe linkage across its working arc.

Importance:

Essential for achieving precise slewing control and rapid operational cycle times during trenching, excavation, and side-dumping activities. Engineered from high-tensile steel to absorb severe dynamic shock loads and rapid directional changes, while heavy-duty internal seals prevent hydraulic drift and internal pressure bypass under load.
