The WG2210100109 Range Selector Synchronizer Ring is a premium, heavy-duty chassis transmission component engineered specifically for SINOTRUK Howo trucks, providing the critical friction surface that equalizes gear speeds for smooth, clash-free range shifts. As a trusted supplier of genuine Sinotruk howo parts, we offer this OEM-grade synchronizer ring as a direct replacement for the original factory unit. The WG2210100109 ring ensures correct fitment, reliable synchronization and dependable operation on Howo A7, T7H, HOWO 371 and HOWO 380 models equipped with the HW19710 transmission.
Manufactured from high-strength steel with precision-machined cone surfaces, accurately cut blocker teeth and a wear-resistant friction finish, this range selector synchronizer ring is built to exact OEM dimensions. Its robust construction maintains consistent friction characteristics, resists heat, shock loading, oil degradation and temperature extremes, and performs reliably in constant commercial truck service.
OEM WG2210100109 • Range selector synchronizer ring • High-strength steel • Clash-free shifting • Direct OEM fit
This range selector synchronizer ring is a critical wear component inside the auxiliary gearbox of SINOTRUK Howo trucks. It sits between the range gear cone and the sliding sleeve, acting as a friction cone that matches the rotational speed of the gear to the sleeve before engagement.
The ring is machined to exact OEM dimensions. Cone angle, blocker tooth profile, ring thickness and oil drainage grooves all match the factory specification, so it seats correctly against the gear cone and provides consistent synchronization during high/low range changes.
Common signs that a range selector synchronizer ring needs replacement include grinding or crunching when shifting between high and low range, difficulty engaging range gears, a delay or hesitation during range changes, and metallic debris or friction material found in the transmission oil.
Fitting a new WG2210100109 Range Selector Synchronizer Ring restores smooth, clash-free range shifting and protects the range gear, sliding sleeve and bearings from shock and accelerated wear. It is a durable repair that extends the service life of the HW19710 transmission.
This range selector synchronizer ring is designed for SINOTRUK Howo trucks equipped with the HW19710 transmission, with primary compatibility across the A7, T7H, HOWO 371 and HOWO 380 series. It is a direct OE replacement, so it fits the original range gear cone and sliding sleeve without modification.
The ring is essential in applications where smooth high/low range shifting is critical, such as long-haul transport, construction, mining and municipal service. In these duties, it must resist repeated friction cycles, heat, shock loading and contaminated transmission oil.
When replacing the synchronizer ring, it is recommended to inspect the range gear cone, sliding sleeve, blocker teeth, bearings and transmission oil for wear or damage. This part is designed to work with the factory synchronizer assembly for correct fit and reliable operation.
For fleets with multiple HOWO trucks, standardising on the WG2210100109 Range Selector Synchronizer Ring simplifies transmission maintenance and ensures the correct part is available for scheduled service or emergency repairs.
Replacing the WG2210100109 Range Selector Synchronizer Ring is a precision transmission repair that requires a clean workshop, bearing pullers and measuring tools. This work should be performed by a qualified technician.
Remove the auxiliary gearbox cover and range gear assembly. Take out the worn synchronizer ring and inspect the range gear cone, sliding sleeve and blocker teeth for scoring, rounding or heat damage.
Fit the new synchronizer ring onto the gear cone, ensuring the blocker teeth align correctly with the sliding sleeve. Reassemble the range gear assembly and check that the ring moves freely without binding or excessive play.
Refill with the specified transmission oil and road test through high and low range shifts. During routine service, change the transmission oil at the recommended interval and listen for grinding or hesitation during range changes.
This range selector synchronizer ring is manufactured in an ISO 9001-certified facility using high-strength steel and a wear-resistant friction finish. Incoming steel is checked for hardness, chemical composition and surface quality before machining begins.
Each ring is machined, heat-treated and finished on precision equipment, then inspected for cone angle, blocker tooth profile, ring thickness and friction surface condition. Every batch is dimensionally checked, and samples receive a friction and durability test before packing.
Batch samples undergo thermal cycling, oil immersion, wear and fatigue testing to confirm long-term reliability in heavy-duty truck use. These checks help ensure the synchronizer ring performs in the tough conditions Howo trucks face every day.
This synchronizer ring is covered by a 12-month warranty against material and workmanship defects. Strict quality control means every unit matches the fit, function and durability of the original factory part.
The WG2210100109 Range Selector Synchronizer Ring is a vital component for maintaining smooth range shifting, protecting the range gear and ensuring reliable transmission operation on your Howo truck. A worn or damaged ring causes grinding, hesitation and shock loading that can damage the gearbox.
Manufactured from quality steel with a precision friction surface and accurate blocker teeth, this synchronizer ring offers dependable synchronization and long service life. Its direct-fit design keeps installation simple and works with the factory HW19710 synchronizer assembly.
Fleet operators benefit from reduced transmission repair downtime, lower maintenance costs and improved vehicle availability. Owner-operators gain confidence from a synchronizer ring that meets strict OEM standards and is backed by a 12-month warranty.
Order the WG2210100109 Range Selector Synchronizer Ring today and keep your SINOTRUK Howo transmission shifting smooth, quiet and reliable for years to come.
