The following is precise original part information:

Core Parameters and Compatibility Information

Item Details
Part Model: CAT 536-2629 SEM Genuine Steel Bushing (for positioning and adjustment), weighing approximately 0.08 kg (0.176 lb), used for gap compensation, positioning, and fastening between mechanical components, suitable for mounting structures with a shaft diameter of approximately 25 mm.

Core Material: High-quality carbon steel, blackened/galvanized surface, hardness HB 180-220, rust-proof and corrosion-resistant, suitable for dusty and humid outdoor conditions, preventing positioning deviations caused by rust and ensuring component fit accuracy.

Key Dimensions: Inner diameter approximately 25.00 mm (0.984 in), outer diameter approximately… 30.00 mm (1.181 in), total length approximately 12.00 mm (0.472 in), tolerance grade IT8, transition fit with shaft (clearance 0.005-0.015 mm), suitable for positioning structures with a standard shaft diameter of 25 mm.

Structural Features: Thin-walled cylindrical shape, no chamfer/flange design, smooth and burr-free edges. Used to fill component installation gaps, ensuring a tight connection and preventing loosening or misalignment. Suitable for medium to light load positioning and adjustment conditions.

Compatible Models: Compatible with chassis linkages, hydraulic cylinder trunnions, gearbox housings, etc. of CAT 320GC/323GC excavators, 906M/907M mini loaders, and 420F2 backhoe loaders for component positioning and clearance compensation.

Accessories: Compatible with CAT 5P-3510 bearing puller, 4C-9520 mounting punch, and compatible with CAT… 356-5975/6D-4189 Fixture Use: Installation requires a tight fit with the component to ensure accurate positioning.

Core Functions and Installation Points:

Gap Compensation and Positioning: Fills the installation gaps between mechanical components, ensuring a tight fit and preventing loosening or displacement due to vibration. Reduces component wear and is suitable for medium to light load positioning conditions.

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

Use cold pressing to press the bushing into the mounting hole, ensuring coaxiality with the shaft. After pressing, check for looseness and jamming.

Tighten the fixing component to the torque specified in the machine manual (typically 5-8 N·m). After installation, ensure no axial movement and stable component positioning.

Maintenance Recommendations:
Inspect the bushing for wear, rust, and loosening every 400-600 working hours. Replace with original parts immediately if wear exceeds 0.05 mm or if rust or deformation is observed.

Use only CAT 536-2629 SEM original bushings to avoid misalignment or loose parts due to size/material mismatch.
