Volvo A40G Articulated Hauler Spare Parts — Hydraulic, Suspension and Brake Wear List for European Quarries (2026)
Where an A40G spends its maintenance budget
| Group | What fails | Symptom the operator notices | Inspection |
|---|---|---|---|
| Hydraulic pumps | Piston / gear pump wear, shaft seal | Slow body raise, hot oil, whine rising with rpm | Read case drain flow and pressure at rated rpm |
| Suspension | Damping cylinder wear, lost nitrogen charge | Harsh ride, machine leans when loaded | Check ride height and look for accumulator weep |
| Articulation | Articulation switch, bearings, pins | Steering lag,wandering on the straight | Rock the frame with the engine off |
| Brakes | Retarder performance, brake packs, wheel seals | Long stopping distance, hot hub | Feel hub temperature, test on a defined ramp |
| Body and hoist | Hoist cylinders, bushings, gasket kits | Body drifts down, oil around the cylinder rod | Check drift with the body raised |
The A40G shares part numbers with earlier models — that is the trap
A35, A35F, A40D, A40E, A40F and A40G run a long family line. Several pump references cross several of them, but cross-compatible does not mean plug-compatible: flange shapes, shaft rotation, port positions and drive ratios changed between generations. Always quote the serial number and, if possible, read the number stamped on the old pump body. That single step is what separates a one-day repair from a two-week wait.
The parts we ship most for this platform
- Main hydraulic pump: 11707968 hydraulic pump serves A35F / A35G / A40F / A40G units — verify the mounting flange and shaft before ordering.
- Gear pump: where the machine uses a separate fan / pilot section, 15020177 hydraulic gear pump is used across A35F / A35G / A40F / A40G.
- Damping cylinder: ride quality and tyre life both drop fast once a damping cylinder goes soft. Check 11119171 damping cylinder when the machine starts leaning loaded.
- Gasket kits: every suspension or gearbox reseal needs a full set, not a selection. 15090812 gasket kit covers A35E / A40E / A35F applications.
- Articulation switch: intermittent steering faults are frequently one switch, not a hydraulic rebuild. Test 23945381 articulation switch before spending on pumps.
European quarry duty: what actually differs
- Long sustained grades: retarder and brake packs take far more load than on flat hauls, so oil temperature, not hours, should drive your inspection interval.
- Cold mornings, hot afternoons: viscosity swing stresses seals; check for weeping at every service in spring and autumn.
- Strict noise and spill rules: a leaking hose is not cosmetic, it is a compliance issue. Fix weeping seals the week you see them.
How we confirm fitment before quoting
Send: machine serial number, a photo of the machine plate, the stamped number on the old part and one photo of the installation position. We reply with stock status, warehouse photos of the actual piece and a firm price. Nothing ships until you have confirmed the fitment against those photos — that is how we keep "wrong part" returns off your schedule.
Packing and shipping
Seal kits, switches and small hydraulic parts ship by courier. Pumps, damping cylinders and complete gearbox kits are crated with machined faces protected separately, loaded with a packing list showing per-piece dimension and weight, and a loading video before departure. Third-party inspection is available for larger orders.
FAQ
Are A40F and A40G parts interchangeable?
Some references overlap, but do not assume it. Flange shape, shaft rotation, port positions and drive ratios changed between generations. Quote the serial number and the stamped number on the old pump before ordering.
Body drifts down when raised — pump or cylinder?
Test before buying. Hold the body up and watch the drift rate, then isolate the hoist cylinder. If the drift disappears when the cylinder hose is plugged, the cylinder is passing internally; if not, look at the control valve or the pump.
How often should damping cylinders be checked?
At least at every scheduled service, and immediately whenever the machine starts leaning loaded or the ride turns harsh. A soft damping cylinder costs you tyre life long before it strands the machine.
Do you supply complete reseal kits?
Yes. We prefer supplying a complete gasket kit rather than individual seals, because a reseal with a torn-old gasket left in place ends up costing another teardown.
Need A40G parts priced?
Send the serial number and the old part number — we confirm fitment and send warehouse photos the same day.
