Volvo articulated haulers — the A-series — are among the most demanding machines on any site. Whether dumping 25 tonnes of overburden in a quarry or hauling aggregates across soft ground, these trucks put extreme loads on their drivetrain, suspension, body hoist systems, and tyres. When something fails, the whole haul cycle stops. This guide covers every major part category for Volvo A25, A30, A35, A40, and A45 haulers, with direct links to verified parts pages so you can get back to work fast.
Volvo A-Series Articulated Hauler Overview
The Volvo A-series covers payload capacities from 24 to 45 tonnes. Each model shares a common design philosophy — all-wheel drive, oscillating front axle, and automatic transmission — but varies significantly in size, engine output, and component dimensions. Use the table below to identify your model and jump straight to its parts page.

Most Common Replacement Parts for Volvo Articulated Haulers
Articulated haulers are high-stress machines — constant load cycles, rough terrain, steep gradients and all-weather operation wear out specific components faster than almost any other machine type. Here are the systems that generate the highest parts demand.
1. Body Hoist & Hydraulic System
The body hoist is the most heavily cycled hydraulic system on a hauler — lifting a fully loaded 40-tonne body hundreds of times per day. Hoist cylinder seals, hydraulic pump assemblies, hose assemblies, and control valve blocks all wear at an accelerated rate in high-production environments. Contaminated hydraulic fluid is the primary cause of premature failures in this system. Browse all Volvo hauler hydraulic parts.
2. Power Transmission & Axles
Volvo A-series haulers use automatic gearboxes with six forward gears and full-time all-wheel drive. The transmission, front axle differential, rear bogie axles, and inter-axle differential locks take enormous loads — particularly on haul roads with steep grades. Filter kits, axle shaft seals, planetary gear sets and differential carrier bearings are frequent replacement items. Browse power transmission parts and frame, axle and suspension parts.
3. Engine & Fuel System
Volvo D-series and TAD-series engines power the A-series haulers, with output ranging from 272 to 456 hp depending on model. High-cycle operation means regular servicing of air filters, fuel filters, injectors, coolant hoses, and thermostat kits. Turbocharger assemblies and intercooler hoses are also common wear items in high-altitude or dusty site conditions. Browse engine parts.
4. Suspension & Frame
The independent front suspension and rear bogie suspension system on Volvo haulers absorbs enormous shock loads. Suspension cylinder rebuild kits, rubber isolator bushings, bogie pivot bearings, and oscillation bearing assemblies are among the most frequently ordered structural parts. The articulation joint — connecting front and rear frames — also requires regular greasing and periodic bearing replacement. Browse frame and suspension parts.
5. Brakes
Volvo articulated haulers use wet disc brakes on all six wheels, with separate parking brake systems. Loaded haul road descents put extreme thermal loads on brake discs and cooling circuits. Brake disc packs, caliper seals, and brake oil cooler kits are regularly needed — especially on sites with long downhill grades. Browse brake components.
6. Cab, Electrical & Body
Operator cab wear items — door seals, HVAC components, wiring harnesses, sensors and instrument modules — are in continuous demand on older A-series machines. Body wear plates, tail gate hinges, and tailgate locking components are also commonly replaced due to impact and abrasion damage in quarry and mining operations. Browse electrical parts and cab and exterior parts.
Model-by-Model Breakdown
Volvo A25 — The Compact Hauler
The A25 is Volvo’s entry-level articulated hauler, favoured in road construction, residential earthworks, and confined quarry sites where larger machines cannot manoeuvre. At 24 tonnes payload and powered by a 272 hp Volvo D7 engine, it generates less stress on structural components than larger models — but hydraulic and transmission wear rates remain high due to the intensity of loading cycles in typical A25 applications.
Top service items: Hoist cylinder seal kit, transmission oil filter, engine air cleaner, front axle differential seals, suspension cylinder rebuild kit, cab door seal set.
Volvo A30 — The All-Rounder
The A30 is one of the most widely deployed Volvo haulers worldwide. Its 28-tonne payload capacity and 309 hp engine make it a versatile machine suitable for general earthworks, mining, and large infrastructure projects. The A30F and A30G variants are the most common in the field, with extensive parts availability across drivetrain, hydraulic, and body systems.
Top service items: Rear bogie bearing kits, hydraulic pump rebuild, fuel injector sets, axle oil seals, turbocharger assemblies, articulation pin and bushing kits.
Volvo A35 — The Production Hauler
The A35 steps up to 33-tonne payload capacity and is the preferred machine for high-production quarrying and large-scale earthworks. The 362 hp Volvo D12 engine delivers strong rimpull across a wide RPM range. At these payload levels, rear bogie axle maintenance becomes critical — planetary gear sets and bogie shaft seals are priority items. The A35F and A35G are the most common variants in the fleet.
Top service items: Bogie axle planetary gear kits, hoist cylinder seals, brake disc assemblies, transmission clutch packs, differential locking solenoids, engine mount kits.
Volvo A40 — The Heavy Hauler
At 39 tonnes payload and powered by a 430 hp engine, the A40 is built for heavy mining and large infrastructure projects. The additional axle loading on this model means axle and suspension components wear significantly faster than on smaller models. Hoist system maintenance is also more demanding — the larger body and greater payload create higher hydraulic pressures throughout every dump cycle.
Top service items: Full suspension overhaul kits, hoist ram seal sets, axle shaft assemblies, transmission oil cooler, brake pad disc packs, cab pressurisation filter units.
Volvo A45 — The Largest Hauler
The A45G is Volvo’s largest standard articulated hauler, with a 41-tonne payload and 456 hp engine. Designed for the most demanding mining and quarry operations, the A45 is typically found in fleets where maximum volume production is the priority. At this scale, complete component rebuilds rather than individual part repairs are common practice — including full drivetrain, hoist cylinder and suspension overhauls at scheduled intervals.
Top service items: Full hoist cylinder rebuild kits, rear bogie overhaul kits, transmission rebuild components, articulation frame bearing sets, large-bore hydraulic hose assemblies.
