Part Number / OE No.: 8009104550002
Part Name: synchronizer ring
Purpose: replacement for aftermarket
Origin: China
Cross-reference: Massey Ferguson: 1684022M1 / Brass4022M1
Alternate IDs: K8021, SXCJ1148
Material: High-grade Brass Alloy (for superior friction properties)
Main Application: Massey Ferguson, Valtra, and various Chinese tractor brands
*The 8009104550002 ring serves as the friction interface between the sliding sleeve and the gear cone.
Application Scope
This synchronizer ring is widely found in:
Transmission Types: Synchromesh manual gearboxes (often 8×2 or 12×4 configurations).
Compatible Equipment:
Massey Ferguson: Various tractor series requiring the 1684022M1 specification.
Valtra: Compatible industrial and agricultural models.
Generic Industrial Gearboxes: Used in several specialized Chinese-manufactured drivetrains.
Installation Note: When replacing the 8009104550002 synchronizer ring, it is essential to inspect the synchronizer hub and sliding sleeve for wear. If the ring has been worn down to the point of gear grinding, the mating teeth on the gear itself may also require inspection to ensure long-term reliability.
The 8009104550002 synchronizer ring is a precision-engineered component designed to replace aftermarket parts in various manual transmissions, particularly for agricultural and industrial applications. Made from high-grade brass alloy, this ring ensures superior friction properties, which are crucial for smooth gear engagement and long-lasting performance in synchromesh manual gearboxes. It serves as the critical friction interface between the sliding sleeve and the gear cone, allowing for the seamless synchronization of gear speeds before engagement, thereby reducing gear wear and preventing grinding. This part is specifically cross-referenced with Massey Ferguson’s 1684022M1 and Brass4022M1 specifications and is also known under alternate IDs such as K8021 and SXCJ1148. Its main applications include a wide range of Massey Ferguson tractors, Valtra industrial and agricultural models, and several Chinese-manufactured tractor brands, making it a versatile solution for maintenance and repair operations. The 8009104550002 synchronizer ring is compatible with synchromesh transmissions, often found in 8×2 or 12×4 gearbox configurations, where reliable and precise gear shifting is essential for optimal tractor operation. When installing this component, it is highly recommended to inspect not only the ring but also the synchronizer hub and sliding sleeve for signs of wear. If the existing ring has been severely worn or damaged, resulting in gear grinding, the mating teeth on the corresponding gears should also be examined and potentially refurbished or replaced to maintain long-term reliability and performance. With its durable construction and broad compatibility, the 8009104550002 synchronizer ring offers an effective, high-quality solution for maintaining smooth and efficient transmission operation in a variety of tractors and industrial machinery. This ensures that equipment remains operational with minimal downtime, extending the overall lifespan of the drivetrain components while maintaining safety and efficiency in demanding agricultural and industrial environments.
