V-BELT(6PK1864) (KU-3J03666330)
Description:
The Kubota KU-3J03666330 V-Belt (6PK1864) is a genuine OEM multi-rib drive belt designed to deliver efficient and reliable power transmission for compatible Kubota engine accessory systems. Manufactured to Kubota’s exact specifications, this 6-rib poly-V belt with an effective length of 1864 mm provides superior grip, smooth operation, and dependable performance in demanding agricultural and industrial environments.
As a result, it efficiently transfers power to driven components such as air conditioning compressors, cooling systems, and auxiliary engine accessories while maintaining consistent performance under varying operating loads. Furthermore, the multi-rib design provides greater contact area than conventional V-belts, helping reduce slippage and improve drive efficiency.
Constructed from high-quality heat-resistant and oil-resistant rubber compounds with reinforced tensile cords, the 3J036-66330 belt offers excellent resistance to stretching, cracking, abrasion, and wear. Consequently, it maintains proper tension and reliable performance throughout extended service intervals, even in harsh operating conditions.
Designed as a direct OEM replacement, this Kubota V-belt ensures precise fitment and optimal pulley engagement. Therefore, it helps maintain factory performance standards while reducing the risk of premature belt wear, accessory drive issues, and unexpected downtime. Regular inspection and replacement of drive belts are essential for maintaining cooling, charging, and air conditioning system performance.
