Forgings are done to exacting specifications set by Ashok Leyland.
Forged blanks are isothermally annealed at closely controlled temperatures to obtain uniform dimensions after heat treatment.
Uniform case hardening is done at controlled atmospheric temperature and press quenched to avoid distortion.
Selective case hardening is done to import maximum strength to the pinion to maximize wear resistance.
After hardening, the crown wheel & pinions are tempered to closely controlled temperature to remove thermal stresses.
The crown wheel and pinion are paired and checked for centralized tooth bearing and desired proximities.
