Compatible Machinery: Caterpillar Backhoe Loaders (416D, 420D, 430D, 430E, 430F, 432D, 438D, 442D, 442E, 444E, 446D series)

What It Does:

Serves as the cylinder head (gland assembly) mounted at the front end of the backhoe bucket hydraulic cylinder on Caterpillar 400 series backhoe loaders. It securely closes the front section of the cylinder barrel to contain high-pressure hydraulic fluid while providing precision guiding and alignment for the reciprocating piston rod. Housing rod seals, buffer rings, wiper seals, and wear bands, it maintains high-pressure hydraulic sealing and prevents external contaminants such as abrasive dust, mud, and moisture from entering the cylinder.

Importance:

A critical structural and sealing component essential for rod alignment, smooth stroke cycling, and total fluid retention during heavy trenching, excavating, and bucket breakout operations. Precision-machined to fit a 95.25 mm bore cylinder with a 3 kg heavy-duty construction, it effectively absorbs dynamic shock pulses, side loads, and mechanical vibrations transmitted through the bucket linkage, protecting internal seals, reducing rod scoring, and preventing external oil leakage under continuous demanding site operations.
