This OEM WG2210100126 range synchronizer gear (range cone) is original standard gearbox spare part exclusively designed for Sinotruk HOWO trucks equipped with HW19710 10-speed transmission, strictly manufactured in accordance with OEM tooth count, spline size and mounting hole standards for direct replacement without modification.
Made of high-strength alloy steel with integral carburizing and quenching heat treatment, the gear surface achieves high hardness and strong anti-fatigue performance, effectively resisting heavy load impact and long-term friction loss under mining, logistics and construction harsh working conditions. The precise internal involute splines match the main shaft perfectly, and the outer synchronous dog teeth cooperate closely with the synchronizer sliding sleeve to buffer gear shifting impact, avoid gear jumping, grinding and difficult shifting faults.
As the key load-bearing part of the auxiliary high-low range synchronizer, it undertakes torque transmission during high and low gear switching, greatly improving shifting smoothness and extending the overall service life of the gearbox synchronizer assembly. All finished gears pass strict hardness and dimensional inspection before delivery to guarantee zero installation deviation and abnormal wear after assembly.
It is the ideal replacement part for worn, cracked, tooth-collapsed original synchronizer gears during gearbox overhaul, widely supplied to truck repair shops, logistics fleet maintenance stations, transmission repair factories and global heavy truck gearbox spare parts wholesalers. We have sufficient spot inventory, stable quality control and competitive factory direct wholesale prices for worldwide buyers.
