Aftermarket Hyundai HD78 Engine Flywheel Ring Gear 114T 23212‑45000

This durable Engine Flywheel Ring gear with OEM number 23212‑45000 and reference number 348.5316151 is a critical aftermarket replacement component designed for Hyundai HD78. Built with 114‑tooth structure, this flywheel ring gear is pressed onto the outer edge of flywheel, meshing with starter pinion to drive engine cranking during startup. A chipped, cracked or heavily‑worn Engine Flywheel Ring will cause starter slipping, grinding metallic noise, difficult starting and even complete engine cranking failure. For Hyundai HD78 commercial vehicles working in frequent start‑stop logistics and delivery scenarios, timely replacement of defective ring gear can protect the starter motor and avoid unexpected vehicle downtime.
 

Made of high‑strength alloy steel material, this Engine Flywheel Ring gear is manufactured through precision forging and high‑frequency quenching heat‑treatment. The tooth surface gains high hardness and strong impact resistance to withstand repeated starter engagement impact. Every unit is strictly inspected on inner diameter, tooth profile and overall dimension to ensure perfect press‑fit installation on the original flywheel. Heavy‑load driving, aging components and improper starter engagement will gradually damage teeth on an Engine Flywheel Ring. Replacing only the ring gear instead of purchasing a full flywheel assembly is a very cost‑effective maintenance solution for repair shops and fleet operators.

Application & Fitment

This Engine Flywheel Ring gear is specially produced for Hyundai HD78, widely applied for freight transport fleets, local repair workshops and complete engine overhaul projects. It matches original inner diameter, tooth shape and 114‑tooth parameters for direct press‑in fitting without extra modification. Before submitting your order, please double‑check your original part number and tooth quantity to confirm correct fitment and reduce return risks. Many overseas maintenance technicians choose this separate ring gear part to cut overall repair cost during diesel engine service.
