CAT 126-9341 17.01mm Width Sleeve for eccentric weight housing

CAT 126-9341 is a Caterpillar genuine eccentric counterweight housing sleeve, suitable for eccentric counterweight mechanisms in vibrating equipment such as road rollers. It protects the housing, positions the components, reduces vibration wear, and ensures stable operation of the eccentric block (Cat®…).

Core Technical Parameters

Item Details
Part Model: CAT 126-9341 Eccentric Counterweight Housing Sleeve

Material: High-strength carbon steel/alloy steel, surface treated with blackening, galvanizing, or powder coating; wear-resistant and corrosion-resistant, suitable for vibration conditions.

Key Dimensions: Width 17.01mm; inner/outer diameter matches the eccentric counterweight housing and shaft diameter (subject to actual product and manual); precise fit ensures positioning and protection (Cat®…).

Compatible Models: Eccentric counterweight housings for vibrating equipment with eccentric counterweights, such as road rollers CS-56B/CS-68B, vibratory plate compactors, and pavers.

Performance Characteristics High-rigidity structure resists vibration and impact; surface treatment enhances wear resistance and corrosion resistance; precise dimensional fit prevents housing wear and displacement during eccentric block operation.

Structure and Core Functions

Housing Protection and Positioning: Installed between the eccentric counterweight housing and the shaft, it isolates the eccentric block from direct contact with the housing, reducing housing wear caused by vibration friction. It also provides precise positioning for the eccentric counterweight mechanism, preventing displacement during operation.

Vibration Buffering and Stabilization: Adapts to high-frequency vibration conditions in vibrating equipment, absorbing some vibration energy, reducing housing vibration stress, and extending the service life of the eccentric counterweight mechanism.

Sealing, Dustproofing, and Contamination Prevention: Prevents dust, oil, and other impurities from entering the eccentric counterweight housing, protecting internal parts and reducing malfunctions.

Installation and Maintenance Points
Installation Specifications: Clean the eccentric counterweight housing mounting surface and shaft diameter, removing oil, rust, and impurities. Check for scratches and deformation on the surface, ensuring a proper fit of the sleeve.

Use press-fitting or specialized tools for installation; avoid hammering to prevent sleeve deformation that could affect fit accuracy. After installation, check the fit between the sleeve and the housing/shaft; ensure there is no looseness or excessive clearance.

Check the installation position and tightening status according to the equipment manual to ensure smooth operation of the eccentric counterweight mechanism.

Maintenance Recommendations: Every 800-1000 working hours, check the sleeve for wear, deformation, cracks, excessive clearance, and intact surface coating.

Regularly clean the eccentric counterweight mechanism and replenish lubricating grease to reduce friction between the sleeve and the shaft/housing.

Replace the sleeve immediately if it is severely worn, deformed, or cracked to prevent damage to the eccentric counterweight housing and shaft.
