Mining Dozer Parts: CAT D10, D11, Komatsu D375 and Every Ultra-Class Dozer Platform

Where the Mining Dozer Begins and Where the Boundary Sits

The bulldozer parts range within this machinery collection covers the full civil and construction dozer spectrum, from CAT D3 through D9, Komatsu D20 through D65, and every comparable platform deployed across earthmoving, land clearing, and civil construction. That page is the right destination for those machines.

This page begins at D10. The CAT D10 and D11 series, Komatsu D375 through D575, Liebherr PR756 and PR776, and Shantui SD42 and SD52 are machines in a different engineering class, ultra-class crawler dozers built specifically for the operating demands of large-scale mining. The component specifications, undercarriage dimensions, and blade system engineering on these platforms share nothing with construction-grade dozer equivalents, and sourcing them requires a catalogue that starts from that distinction, not one that treats them as scaled-up versions of smaller machines.

What Mining Dozers Actually Do and Why That Shapes the Parts Requirement

A mining dozer is not primarily a blade machine in the way a civil dozer is. On a large open-cut mine, ultra-class dozers perform three functions that nothing else in the fleet handles:

• Dump management — pushing and compacting overburden on active waste dumps, maintaining the dump's structural integrity and access road profile under continuous truck tipping traffic
• Haul road maintenance — re-sheeting and grading haul road surfaces under production traffic loads that exceed any public road specification, maintaining the road geometry that allows haul trucks to operate at their designed speed and payload
• Ripping — fracturing competent rock and cemented ground ahead of excavators and scrapers using multi-shank ripper assemblies that generate drawbar pull measured in hundreds of kilonewtons.

These operating functions concentrate wear in specific systems, blade cutting edges and end bits consume under dump push conditions, ripper shanks and tips have finite penetration life measured in operating hours, and the undercarriage absorbs continuous load across haul road surfaces that are abrasive, rutted, and uneven by any construction site standard. Mining dozer wear parts across all three of those systems are the highest-frequency replacement items in the ultra-class dozer maintenance cycle.

Mining Dozer Parts by Brand and Platform

CAT Mining Dozer Parts

The CAT D10 and D11 series define ultra-class dozing globally. Cat mining dozer parts at Imara Engineering are catalogued across six production variants, each representing a distinct generation with its own powertrain, undercarriage, and blade system specifications:

• Cat D10N parts — the D10N is the first-generation D10 with a specific powertrain configuration that differs from all subsequent D10 variants
• Cat D10R parts — the D10R introduced significant powertrain and hydraulic updates from the D10N generation
• Cat D10T parts — the current D10 generation with updated cab, electronics, and drivetrain specifications, distinct from the D10R
• Cat D10 parts — general D10 series coverage across all production variants, where generation identification requires serial number confirmation
• Cat D11T parts — the D11T is one of the largest and most productive crawler dozers ever built, with blade capacity and drawbar pull specifications that place it at the absolute upper boundary of the dozer category. ry
• Cat D11 parts — D11 series coverage across production variants, with serial number confirmation required to establish the correct generation reference

Every cat mining dozer parts order at Imara Engineering is cross-referenced against model designation and serial number before dispatch. The specification differences between D10 generations are not minor, and serial number confirmation is the only reliable way to resolve them.

Komatsu Mining Dozer Parts

Komatsu's large crawler dozer range spans four platform references that together cover the complete ultra-class dozing spectrum. Komatsu mining dozer parts at Imara Engineering are catalogued as distinct model references across the full production range:

• Komatsu D275 parts — the D275 sits at the entry point of Komatsu's large mining dozer range, with undercarriage and blade specifications suited to mid-scale mine site earthmoving
• Komatsu D375 parts — the D375 is one of the most widely deployed large crawler dozers in global mining, with a strong operational presence across open-cut coal, metalliferous, and bulk earthmoving applications.
• Komatsu D475 parts — the D475 steps into ultra-class territory, with operating weight and blade capacity specifications that match the CAT D11 at the upper end of the large dozer category
• Komatsu D575 parts — the D575 is one of the largest crawler dozers ever produced, with a blade capacity and total operating weight that exceeds every other production dozer in the market

Liebherr Mining Dozer Parts

Liebherr's large crawler dozer range carries a technically distinctive engineering approach specific to Liebherr's hydrostatic drive architecture, a drivetrain configuration that produces different component specifications from the conventional powershift transmission platforms used by CAT and Komatsu:

• Liebherr PR776 parts — Liebherr's largest crawler dozer, with hydrostatic drive system components specific to the PR776's engineering configuration
• Liebherr PR756 parts — the PR756 sits below the PR776 in Liebherr's large dozer range, with its own hydrostatic drivetrain and undercarriage specifications

Shantui Mining Dozer Parts

Shantui's large crawler dozer range carries a significant operational presence across Asian, African, and developing market mining operations, where Shantui's competitive positioning has established a substantial active fleet:

• Shantui SD42 parts — a large crawler dozer widely deployed across Chinese and international open-cutt mining operations
• Shantui SD52 parts — Shantui's upper-range large dozer, with blade and undercarriage specifications suited to high-production mine site earthmoving

Key Component Categories: Ultra-Class Dozer Wear and Maintenance

Across every platform in the mining dozer range, the maintenance intensity concentrates on:

• Undercarriage — dozer track components scaled to ultra-class operating weight, including track chains, track shoes, bottom rollers, top rollers, idlers, and sprockets. Dozer track mining applications generate undercarriage wear at rates that standard construction dozer intervals do not predict
• Blade and ground-engaging tools — cutting edges, end bits, and corner wear plates across the full blade width. Mining dozer wear parts in the blade system are replaced on operating hour intervals tied directly to the push material's abrasion ind. ex.
• Ripper system — ripper shanks, ripper tips, and ripper beam hardware. Dozer blade mining and ripping functions both consume ground-engaging components at high rates in competent and abrasive mining ground conditions. ons
• Powertrain and final drive — transmission components, final drive assemblies, and steering clutch hardware across both powershift and hydrostatic drive configurations. ons
• Hydraulic system — blade lift and tilt cylinder assemblies, ripper hydraulic circuit components, and associated sealing and filtration hardware
