CAT 380-7408 Torque Converter Bearing Retainer

CAT 380-7408 (3807408) is a Caterpillar Genuine GD General Duty Bearing Retainer, suitable for light to medium load pin/bearing positioning, preventing axial movement, and used in articulated/support parts of wheel loaders, graders, etc. The following is precise original part information:

Core Parameters and Compatibility Information

Item Details
Part Model: CAT 380-7408 Genuine GD Bearing Retainer, weighing approximately 0.32 kg (0.705 lb), suitable for light to medium load, low to medium speed oscillating/rotating parts, used for axial positioning of bearings to prevent movement, suitable for articulated structures with a pin diameter of 45 mm

Core Material: Low carbon alloy steel sheet, stamped and formed, with galvanized passivation treatment for rust and corrosion resistance, suitable for outdoor humid and dusty conditions, preventing loosening or seizing caused by rust, structural strength and durability meet general operating requirements Cat®…

Key Dimensions: Inner diameter approximately… 50.00 mm (1.969 in), outer diameter approx. 60.00 mm (2.362 in), thickness approx. 9.00 mm (0.354 in), annular with locating step, mounting hole tolerance H7, interference fit with bearing outer diameter, interference 0.01-0.03 mm

Structural Features: Annular locating step design, burr-free edges, precise fit between inner hole and bearing outer diameter, axial positioning to prevent movement, ensuring bearing and pin coaxiality, suitable for light to medium loads and low to medium speeds, compact structure, easy installation (Cat®…)

Compatible Models: Compatible with boom, stick, or steering knuckle support positions of CAT 930G/938G loaders, 140M/160M graders, and 320D/323D excavators for locating YM series sleeve bearings, suitable for light to medium loads.

Accessories: Compatible with CAT 5P-3510 Bearing puller, 4C-9520 mounting punch, used with YM sleeve bearings such as 360-2326/364-5266. Installation requires a tight fit with the bearing end face to ensure precise positioning.

Core Functions and Installation Points

Positioning and Anti-migration: Axially positions the bearing to prevent axial movement during operation, ensuring coaxiality between the bearing and the pin, reducing localized wear and jamming, suitable for light to medium loads and low to medium speed oscillating/rotating conditions.

Installation Specifications
Clean the mounting hole, cage, and bearing surface, checking the cage for deformation, cracks, rust, or other damage.

First, cold press the YM sleeve bearing into the mounting hole, then install the 380-7408 cage into the positioning groove, ensuring a complete fit with the bearing end face without gaps.

Tighten with bolts (torque according to the model manual, typically 10-15 N·m). After installation, check that the bearing rotates freely without jamming, abnormal noise, or axial movement/backlash.

Maintenance Recommendations: Every 600-800 working hours, check the cage for tightness, surface rust, and deformation. If loose, deformed, or severely rusted, replace with genuine parts immediately.

Use only genuine CAT 380-7408 parts to avoid mismatched dimensions/materials that could lead to positioning failure, accelerated wear of the pins and mounting holes, or component failure (Cat®…).
