AT 3B-1464 (3B1464) is a Caterpillar genuine steel end cap used for sealing and protecting the piston rod/cylinder end of hydraulic cylinders, and for axial positioning. The following is precise information (no additional description):
Core Parameters and Information
Item Details
Part Model: CAT 3B-1464 End Cap
Part Type: Hydraulic cylinder end cap, used to seal the piston rod/cylinder end cavity, achieving axial positioning, dust and dirt prevention, and protecting internal seals and guide components.
Material: 42CrMo alloy steel, overall heat treated (hardness HRC28-32), surface anodized black for rust prevention, inner bore with O-ring groove
Key Dimensions: Inner diameter 100.00 mm, outer diameter 130.00 mm, total height 35.00 mm, flange thickness 10.00 mm, inner bore depth 25.00 mm, O-ring groove diameter 115.00 mm 1.50 mm groove width, 1.50 mm groove depth, bolt hole distribution circle diameter 118.00 mm, 6 bolt holes, bolt hole diameter 10.00 mm
Structural Features: Disc-type structure with mounting flange; flange with 6 evenly distributed bolt holes for fixing; inner hole O-ring groove for sealing; end face with positioning stop.
Compatible Structures: Matched with hydraulic cylinder barrel, piston rod guide sleeve, and piston rod sealing assembly for cylinder end sealing and structural positioning.
Applicable Working Conditions: Suitable for high-pressure (≤35MPa), vibration, dust, and -40℃ to 100℃ operating environments in construction machinery; adaptable to pressure oil and dustproof requirements.
Compatible Models:
CAT 966H/972G wheel loaders (boom cylinder, bucket cylinder piston rod end cap)
CAT 320D/323D excavators (stick cylinder, boom cylinder barrel end cap)
CAT D250E/D300E Articulated Trucks (Lifting Cylinder, Steering Cylinder End Covers)
CAT 140H/160H Graders (Scraper Cylinder, Towing Cylinder End Covers)
Installation and Fitting Points: The end cover and cylinder flange face should have a flat sealing fit. O-ring compression should be controlled at 0.3-0.5 mm to ensure a static seal without leakage.
Use a torque wrench to tighten the bolts diagonally, with a tightening torque of 80-100 N·m. The flange face should fit snugly against the cylinder end face without gaps.
Before installation, clean the end cover, cylinder flange face, and O-ring grooves. Check the end cover for cracks and deformation, and the grooves for burrs and dents.
Radially, the piston rod is positioned by the inner hole and guide sleeve; axially, it is limited by the flange face fitting snugly against the cylinder. After installation, check that the piston rod extends and retracts smoothly without jamming, and that there is no oil leakage at the sealing points.
According to the model manual, check the tightness and sealing of the end cover bolts every 2000 working hours, and deal with any loosening or oil leakage in a timely manner.
