CT 3P8681

Frequently Asked Questions

Q: What is the CT 3P8681 bearing cone and what equipment does it fit?
A: The CT 3P8681 is a tapered roller bearing cone designed for Caterpillar manual pallet jack wheel and final drive assemblies. It has a 25.40-mm bore diameter and is manufactured from through-hardened bearing-grade steel. This component is compatible with Caterpillar manual pallet jack models 247, 247B, 257, and 257B. The alternate model designation is CT3P8681.

Q: What are the material specifications and durability of the CT 3P8681?
A: The CT 3P8681 bearing cone is manufactured from through-hardened bearing-grade steel, engineered for high-stress rolling contact in pallet jack wheel applications. The through-hardened construction provides consistent hardness throughout the bearing, ensuring reliable performance under repeated load cycles typical of manual material handling equipment. This material specification supports long service life with proper lubrication and maintenance.

Q: Which Caterpillar pallet jack models use the CT 3P8681 bearing cone?
A: The CT 3P8681 is compatible with Caterpillar manual pallet jack series 247, 247B, 257, and 257B. These models use this tapered roller bearing cone in their wheel hubs and final drive assemblies. Verify your pallet jack model and serial range match before ordering. Incorrect bearing cone sizing can cause poor load wheel performance and accelerated wear.

Q: How does bearing cone condition affect pallet jack wheel performance?
A: A worn or damaged bearing cone causes increased friction, rough wheel rotation, and premature tire wear on pallet jack load wheels. Symptoms include grinding noise, reduced wheel rolling speed, and difficulty maneuvering the jack. Inspect bearing cones during routine maintenance and plan for replacement if you observe these conditions. Proper bearing maintenance extends wheel life and improves material handling efficiency.
