CAT 6E-0746 SLEEVE

CAT 6E-0746 (6E0746) is a Caterpillar genuine steel locating sleeve, primarily used for positioning shaft ends/holes in engine fuel systems, hydraulic valve assemblies, or chassis connecting rods. It serves to compensate for clearances, prevent loosening, and provide coaxial guidance. The following is cross-verified accurate information for the genuine part:

Core Parameters and Compatibility Information (Simplified Version)

Item Details
Part Model: CAT 6E-0746 Genuine steel locating sleeve, weighing approximately 0.12 kg (0.265 lb), suitable for locating structures with a shaft diameter of approximately 16 mm, used for filling gaps and coaxial positioning of components…

Core Material: High-quality carbon steel, blackened/galvanized for rust prevention, hardness HB 180-220, deburred edges, suitable for outdoor dusty and humid conditions in construction machinery, preventing positioning deviations caused by rust.

Key Dimensions: Inner diameter approximately 16.00 mm (0.630… 22.00 mm (0.866 in) outer diameter, approximately 28.00 mm (1.102 in) total length, tolerance grade IT8, transition fit with shaft (fit clearance 0.005-0.012 mm), suitable for mounting holes with a standard shaft diameter of 16 mm.

Structural Features: Thin-walled cylindrical shape, no flange/bevel design, used to fill the mounting clearance between the shaft and the hole, ensuring component coaxiality, preventing loosening or misalignment due to vibration, suitable for medium to light load positioning conditions.

Compatible Models: Suitable for CAT 302.7CR/303.5E2 mini excavators, 906M/907M loaders, fuel injection systems of C4.4/C7.1 engines, hydraulic cylinder trunnions, gearbox housing positioning holes, etc., for component positioning and clearance compensation.

Accessories: Suitable for CAT 5P-3510 bearing puller, 4C-9520 mounting punch, and matching accessories. For CAT 356-5975 fasteners, installation requires a tight fit with the shaft end/hole wall for precise positioning.

Core Functions and Installation Points:

Positioning and Anti-Loosening: Fills the installation gap between components, ensuring a tight connection, preventing vibration-induced loosening or misalignment, ensuring coaxiality, reducing component wear, and suitable for medium to light load positioning scenarios.

Installation Specifications: Clean the sleeve, mounting hole, and shaft surface, checking for deformation, cracks, rust, or other damage.

Cold press into the mounting hole, ensuring coaxiality with the shaft. After pressing, there should be no loosening or jamming.

Tighten the fastener to the torque specified in the machine manual (typically 4-6 N·m). After installation, there should be no axial movement, ensuring stable positioning.

Maintenance Recommendations: Check for wear, rust, and loosening every 400-500 working hours. If wear exceeds 0.04 mm or rust or deformation is observed, immediately replace with genuine parts.

Use only genuine CAT 6E-0746 sleeves to avoid misalignment or loosening of parts due to non-genuine parts being out of size or material.
