TOYOTA 2–3 Synchronizer Hub

Description

The 2–3 synchronizer hub couples the 2nd/3rd sleeve to the main shaft, providing positive dog-tooth engagement and torque transfer. Made from carburized alloy steel for a hard, wear-resistant tooth surface with a tough core, it meets OE tolerances on spline form and faces for perfect fit with the original sleeve, baulk rings and keys—ensuring smooth shifts and long service life.

Specification

Dog Teeth: OE form with lead-in chamfer

Material: SCM415 / SAE 8620 alloy steel (or equivalent)

Heat Treatment: Carburized & quenched

Hardness: HRC 58–62 on dogs/splines; core HRC 30–36

Manufacturing: CNC turning/milling, internal spline broaching, dog-tooth finishing & deburring; ground faces/locating surfaces
