CAT 334-3298 31mm Wide Hydraulic Control Valve Retainer

CAT 334-3298 is a Caterpillar track pin/bushing retainer (open-type elastic retaining ring/circlip), used for axial positioning of track pins/bushings on tracked equipment chassis to prevent the pins/bushings from shifting and falling off during operation. It is suitable for small and medium-sized excavators/loaders, ensuring stable operation of the track system, and is easy to install and reliable in positioning. The following is the core information:

Compatible Models CAT 305.5E2/306E2/307E2 This product is designed for axial positioning of track link pins/bushings in small and medium-sized tracked equipment such as excavators and 906H loaders. It is suitable for track pitches of 120-130mm and operating speeds ≤5km/h.

Performance Parameters: Operating temperature -40℃ to 120℃, elastic deformation ≤0.3mm, impact load ≥5kN, reinstallation cycles ≤5 times (avoiding elastic failure).

Core Functions and Structural Features:

Axial Positioning: Open-type elastic structure, embedded in the positioning groove of the track pin/bushing, restricts axial movement, prevents pin/bushing from falling off, ensures stable track link connection, and avoids derailment risk.

Elastic Compensation: Spring steel material provides continuous preload, adapting to the vibration and impact of tracked operation, compensating for the gap between the pin/bushing and the groove, preventing loosening, and reducing wear.

Corrosion Resistance and Durability: Surface anti-corrosion treatment, suitable for harsh working conditions such as dust, mud, and moisture, extending service life and reducing maintenance frequency.

Easy installation: The open design allows for easy installation by hand or with special snap ring pliers, eliminating the need for complicated tools and enabling quick replacement, thus reducing downtime.
