Product Description

34514801 19 Teeth Gear Assembly is installed in heavy truck transmission and drivetrain systems for torque transfer and gear engagement operation. The 19-tooth gear structure is designed for stable transmission performance under long-distance transport, mining operation, and heavy-load engineering applications.

Gear tooth wear, surface pitting, spline damage, overheating, improper lubrication, or overload operation may cause abnormal gearbox noise, unstable power transmission, gear slipping, vibration, and transmission failure.

This gear assembly is widely used in export fleet maintenance, heavy truck gearbox overhaul, engineering machinery repair, and commercial vehicle drivetrain aftermarket service.

Product Overview

This 19 Teeth Gear Assembly is commonly used on SINOTRUK HOWO and SHACMAN heavy truck transmission platforms equipped with manual gearbox and heavy-duty drivetrain systems for dump trucks, cargo trucks, and tractor truck applications.

Common Field Failure Case

Case 1

Vehicle: HOWO Dump Truck
Mileage: 780,000 KM
Problem: Abnormal gearbox noise during uphill heavy-load operation
Root Cause: Gear tooth surface pitting caused unstable engagement
Solution: Replaced 34514801 19 Teeth Gear Assembly
Loss / Benefit: Restored stable transmission operation and reduced gearbox vibration

Case 2

Vehicle: SHACMAN F3000 Tractor Truck
Mileage: 850,000 KM
Problem: Gear slipping under full-load acceleration
Root Cause: Spline wear caused unstable torque transfer
Solution: Installed OE-standard gear assembly and inspected matching shaft
Loss / Benefit: Improved transmission reliability and reduced drivetrain downtime

Case 3

Vehicle: Export Fleet Procurement Project
Mileage: Fleet Service Application
Problem: Wrong tooth-count gear supplied
Root Cause: Similar appearance but different transmission ratio
Solution: Verified tooth quantity and gearbox model before shipment
Loss / Benefit: Avoided assembly failure and repeat export freight expense
