Terex Mining Dump Truck: Top 5 Models & Essential Parts

Introduction

The Terex mining dump truck has been a cornerstone of heavy haulage for decades, serving coal mines, copper pits, and aggregate quarries across six continents. Now part of the Hitachi and Volvo legacy, Terex trucks like the TR and MT series remain in high demand for their rugged construction and field-proven reliability. Whether you operate existing Terex fleets or support customers who do, knowing the top models and their critical Terex mining dump truck parts is essential for minimizing downtime. This guide covers 5 popular models and the components you need to stock.

A Brief History of Terex Mining Trucks

Terex’s mining truck lineage began with the Titan and evolved through the TR (rigid frame) and MT (mining truck) series. While new production has transitioned to Hitachi, millions of Terex mining dump truck units remain active worldwide. Parts availability is therefore a major concern for fleet owners, especially in Africa, South America, Russia, and Australia.

Top 5 Terex Mining Dump Truck Models and Their Critical Parts

Model 1: Terex TR100 (100-Ton Class)

The TR100 is arguably the most successful Terex mining dump truck in history. Thousands still operate in gold mines, limestone quarries, and oil sands projects. Its 100-ton payload and mechanical drive make it a favorite for medium-to-large operations.

Essential Terex mining dump truck parts for TR100:

  • Cummins KTTA38 engine components – Injectors, turbochargers, piston rings.
  • Allison CLBT 6061 transmission – Torque converter, clutch packs, valve body gaskets.
  • Rear axle planetary hubs – Sun gears, planet gears, thrust washers.
  • Brake calipers and discs – Wet disc brake system seals.

Model 2: Terex TR60 (60-Ton Class)

The TR60 is a versatile mid-size Terex mining dump truck popular in smaller quarries, construction sites, and developing-world mines. Its smaller footprint allows operation on narrower haul roads.

Essential Terex mining dump truck parts for TR60:

  • Detroit Diesel Series 60 engine parts – Electronic injectors, ECM modules, rocker arms.
  • Allison CLBT 5860 transmission – Mounts, filters, cooler cores.
  • Front strut suspension assemblies – Seals, nitrogen charging valves, wear bands.
  • Dump body hoist cylinders – Piston rods, gland seals, hydraulic hoses.

Model 3: Terex MT3300 (100-150 Ton Class)

The MT3300 represents Terex’s transition to AC electric drive technology. This Terex mining dump truck model offers superior retarding on long downgrades, making it ideal for deep open-pit mines.

Essential Terex mining dump truck parts for MT3300:

  • AC traction motor brushes and bearings – High-wear electrical components.
  • Retarding grids and resistors – Overheat and crack over time.
  • Wheel hub planetary assemblies – Lubrication seals and thrust washers.
  • Cab electronics and display panels – Prone to failure in hot, dusty environments.

Model 4: Terex MT4400 (200-260 Ton Class)

The MT4400 is a true ultra-class Terex mining dump truck, competing with Caterpillar 797 and Komatsu 930E. These giants operate in the world’s largest mines, from Chilean copper to Australian iron ore.

Essential Terex mining dump truck parts for MT4400:

  • MTU/Detroit Diesel 4000 series engine parts – Cylinder heads, injectors, high-pressure fuel pumps.
  • GE AC drive system components – Inverter modules, control boards, cooling fans.
  • Strut suspension wear components – Kingpins, bushings, seal kits.
  • Tire and rim assemblies – 40.00R57 tires and heavy-duty beadless rims.

Model 5: Terex TR35 (35-Ton Class)

The TR35 is the entry-level Terex mining dump truck, often found in small quarries, sand pits, and road construction projects. Simple mechanical systems make it easy to maintain.

Essential Terex mining dump truck parts for TR35:

  • Cummins N14 engine parts – Water pumps, oil coolers, vibration dampers.
  • ZF transmission components – Shift solenoids, clutch drums, output seals.
  • Brake master cylinder and air pack – Rebuild kits and diaphragms.
