A wheel loader spends its life doing the same four motions: crowd, lift, carry and dump. Every one of them loads a different group of parts, and in a granite or laterite quarry the load is roughly double what you would see on a stockpile job. This is the failure order we see most often in export orders:
| Group | Parts involved | Typical symptom | Check |
|---|---|---|---|
| Bucket / GET | Teeth, adapters, edge blade, side cutters | Bucket will not fill, fuel burn climbs | Measure tooth height, look for adapter play |
| Hydraulic drive group | Main pump, charge pump, accumulator, solenoid valves | Slow lift, jerky tilt, drifting boom | Pressure test at rated rpm |
| Articulation frame | Articulation bearings, pins, thrust washers | Clunk on full lock, wander on the haul road | Rock the frame with the engine off |
| Brake / axle | Brake packs, differential seals, wheel bearings | Pulling to one side, hot hub | Feel hub temperature after a shift |
| Filters and fluids | Engine oil, fuel, hydraulic return, breather | Slow drift into overheating | Log pressure drop every 250 hours |
The practical answer is not to buy bigger parts; it is to shorten inspection intervals by about a third and keep one set of GET to swap in while the other is rebuilt.
L110F and L120H are close relatives, but axle ratios, pump displacements and even pin diameters were revised across production years. The only reliable key is the machine serial number. Send us three photos: the machine plate (serial number visible), the part nameplate / stamping on the old part, and the installation position. We cross-check the part number against the serial break before quoting, which removes most "looks right but does not fit" cases.

Most loaders in a quarry do not stop because the engine failed. They stop because the frame articulation developed play, or because the hydraulics went soft. Both are progressive and both give you weeks of warning. A weekly five-minute check — engine off, frame rocked by hand, plus a pressure reading at rated rpm — catches roughly eight out of ten imminent failures before they become downtime.
In dusty regions we recommend cutting the standard interval by about a third and treating every filter change as an oil inspection: look at what is in the filter, not just whether it is clogged. Bronze flecks mean rotating assemblies are wearing; rubber debris means a hose is degrading upstream. That single habit prevents most of the catastrophic failures we get asked to quote replacements for.
Send the part number, the serial number and a photo — we confirm fitment, stock status and send warehouse photos before you pay. Small parts go by international courier; pumps, adapters and structural parts are crated or palletised (heat-treated / ISPM-15 free where required), with machined faces protected separately. Every shipment comes with a packing list showing per-piece dimensions and weights, plus a loading video before departure. Consolidating several lines into one container usually cuts the landed cost per piece noticeably.
No. Serial-number breaks changed axle ratios, pump displacements and pin diameters across production years. Send the machine plate and the stamping on the old part so we can cross-check the exact part number before quoting.
Test charge pressure at rated rpm first. If pressure is on spec but the function is erratic or intermittent, suspect the solenoid, its connector or its coil before replacing the pump. Readingless or obviously low pressure points to the pump group.
Yes. We ship sets together with the matching keepers and pins. Send a photo of one tooth and the adapter so we can confirm the lock type before shipment.
Warehouse photos, nameplate close-ups, a packing list with per-piece dimensions and weights, and a loading video. Large orders can be inspected by a third party.
Send the serial number and the old part number — we confirm stock and send photos the same day.
