Volvo L90H / L120H Wheel Loader Parts — Brake, Cooling and Hydraulic Wear List for South America
Why L90H and L120H fleets in Brazil and Chile fail in the same order
Both machines sit in the same duty class: 3 to 5 cubic metre buckets, continuous loading, and long haul ramps. That duty profile puts almost all the thermal load into two places — the service brakes and the hydraulic oil. Everything else wears later and more slowly.
In Chilean copper operations the ramps are long and the ambient is dry and dusty; in Brazilian aggregate and sugar operations the ambient is hot and humid with fine abrasive dust. Both end at the same place: brakes glaze and the cooling package clogs externally. Recognising that pattern is what keeps the parts bill predictable.
| System | Typical symptom | First field check | Usual fix |
|---|---|---|---|
| Service brakes | Long pedal travel, pull to one side, burning smell | Measure disc thickness and runout | Disc and pad set |
| Hydraulic oil cooler | High oil temp alarm, fan at maximum | Measure inlet/outlet delta T and pressure drop | Cooler core or fan motor |
| Articulation circuit | Steering lag, dead band, machine wanders | Check solenoid coil resistance and pilot pressure | Solenoid valve or seal kit |
| Bucket and GET | Poor penetration, loose linkage | Measure pin and bushing clearance | Edge, teeth, pins and bushings |
| Driveline | Shuttle shock, noise on direction change | Check thrust washer and side gear clearance | Washer, gear or bearing set |
Brakes: the wear item that decides whether the loader stays legal
Wheel loader brakes are not a comfort item — on ramp work they are the primary safety system. The failure mode is rarely sudden. Disc thickness drops gradually, pedal travel increases, and by the time the operator complains the disc is usually below minimum. Measure thickness and runout at every service interval and replace as a set, never one side only.
On this platform we regularly supply 15011845 brake disc for L110F, L110G, L110H and L120H machines. Because the disc and pad set is axle-position sensitive on some serial ranges, we ask for the machine PIN and a photo of the old part before release. Replacing only the disc on a glazed pad set will shorten the new disc life considerably.
Cooling: hydraulic oil cooler and the fan drive circuit
High oil temperature has only three root causes: the cooler core is blocked externally, the cooler is bypassing internally, or the fan drive is not delivering flow. Cleaning the core first costs nothing and resolves a large share of cases. If the core is clean and the temperature is still high, the problem is almost always the fan motor or the cooler itself.
We supply 11110371 hydraulic oil cooler and the matching 11147935 fan motor / piston motor used across the L70 to L120 range. Replacing both together is usually cheaper than replacing one and discovering the second was also worn.
Hydraulics: pump solenoid valves and the articulation circuit
Articulation complaints are frequently electrical, not hydraulic. Before quoting a pump, measure the coil resistance on the articulation solenoid and compare it with specification. A coil that reads open or far out of range explains the lag completely and costs a fraction of a pump.
The part we supply most often here is 15097457 hydraulic pump solenoid valve, with 15044524 as the sibling part on adjacent serial ranges. Both are coil-definition sensitive, so the old part number and the connector photo are required before we ship.
Bucket and ground engaging tools
On abrasive South American material the bucket package is a consumable, not a spare part. The practical rule: replace the cutting edge before it wears back into the adapter, and replace pins and bushings as sets. Worn edges that reach the adapter cost several times more to repair.
We stock 11012887 edge blade for the L110G/H and L120H range. For the differential and driveline side, the side gear 17415136 and thrust washer 11102146 are the two items that usually resolve shuttle shock complaints.
Lead time, packing and documents to South America
Stock items ship the same day; international express is typically 7 to 12 working days. Complete assemblies and heavy parts go by sea, consolidated or full container, with transit confirmed against the destination port. Everything is packed in wooden cases or heat-treated pallets, and we provide a packing list plus loading photos before dispatch.
To quote we need three things: a photo of the machine data plate including the PIN, a photo of the old part number, and a note on the mounting position. With those three we can confirm fitment and stock the same day.
Frequently asked questions
Are L90H and L120H brake parts interchangeable?
Not by model name alone. Part 15011845 covers L110F, L110G, L110H and L120H, but disc and pad sets are axle-position sensitive on some serial ranges. Provide the machine PIN and a photo of the old part before ordering.
The loader runs hot. Should I replace the oil cooler straight away?
Clean the core first. External clogging causes a large share of high-temperature complaints and costs nothing to rule out. If the core is clean and temperature is still high, check the fan motor before replacing the cooler.
Steering is slow. Is the pump failing?
Often not. Measure the articulation solenoid coil resistance first. An out-of-range coil explains the lag and costs a fraction of a pump. Only move to the pump after the electrical side is confirmed good.
How long does delivery to Brazil or Chile take?
Stock items ship the same day and arrive in 7 to 12 working days by international express. Complete assemblies and heavy parts travel by sea, consolidated or full container, with transit confirmed against the destination port.
