XH-8-107A Plastic Gear Ring WAI:76-91821 T37 L29 D70 ID18 for Starter

This plastic gear ring intended for vehicle starters has factory model XH-8-107A and cross reference WAI 76-91821. It comes with a 37-tooth structure, measuring 29mm long, 70mm across the outer diameter and 18mm at the inner bore. Manufacturers form this component via injection molding using tough reinforced engineering plastic. Two layers of anti-friction and thermal-resistant coatings wrap its surface, so it can stand up to rough working areas beneath engine hoods. Every tooth is precisely shaped during production. This fine craftsmanship creates smooth gear contact, which cuts down operational noise and makes the component last much longer in service. Every physical measurement complies with official OEM specifications, allowing mechanics to install it as a straightforward drop-in replacement. It fixes typical starter malfunctions, including cracked gear teeth and inconsistent meshing between matching starter motor assemblies.
