Volvo L110H Wheel Loader Parts - Oil Cooler, Brake Disc and Control Valve Wear List for Spain and Portugal

Hydraulic oil cooler 11110371 for Volvo L110H / L90H / L110E / L220F loaders

Why Iberian quarries wear the cooler and the brakes first

Granite and slate quarries in Galicia, Extremadura and northern Portugal run loaders in a pattern that is hard on two systems: short cycles with the bucket in abrasive fines, and long idling stretches waiting for trucks. Idling keeps the engine hot but the fan slow, so the cooler cores bake dust onto the fins instead of blowing it off.

The failure chain runs like this: cooler fins clog, oil temperature rises, viscosity drops, the control valve leaks internally, the bucket drifts and the operator works harder, brake use increases in the stockpile, wet brake discs wear, abrasive dust enters through the breather, axle oil turns grey, and the brake chatter starts. In Spanish ports the same loader often runs a bulk handling attachment, which loads the hydraulics even harder at low travel speed.

Hydraulic oil cooler 11110371: clean it before you condemn it

11110371 hydraulic oil cooler suits L110H along with L90H, L110E, L120 and L220F loaders. On Iberian sites it fails in two distinct ways, and they need different answers.

External clogging shows as oil temperature climbing through the shift, hydraulic functions getting slower and the fan running continuously. Fix it with compressed air from the engine side, then low pressure water. Never use a high pressure jet from the front: it folds the fins flat and the cooler never recovers. Internal leakage at the core seam shows as oil loss with no visible drip, or oil in the coolant. That needs replacement.

When replacing, also replace the thermostat bypass and check that the fan clutch engages. A new cooler behind a lazy fan clutch will run hot and the customer will blame the part.

Brake friction disc 15011845 for Volvo L110F / L110G / L110H / L120F / L120G / L120H

Brake disc 15011845: grey axle oil means the discs are gone

15011845 brake friction disc is used across L110F, L110G, L110H, L120F, L120G, L120H, L70F, L70G and L90F loaders. These are wet brakes running in axle oil, which is why the cheapest diagnostic in the world works so well.

Drop a sample of axle oil on white paper. Clean oil spreads evenly. Oil with a grey or metallic sheen means friction material is wearing into the oil, and the discs are near the end of life. At that point brake chatter, longer stopping distance and heat at the wheel hub follow within weeks.

Replacing discs is axle-out work. Do both sides and replace the axle seals and breather at the same time. On dusty Iberian sites, a blocked axle breather pressurises the housing and pushes oil past the seals, which is often mistaken for a failed seal.

Control valve 15043827 for Volvo L110G / L110H / L120G and EW series machines

Control valve 15043827: drift is measured, not guessed

15043827 control valve is shared across L110G, L110H, L120G and the EW160E / EW180E wheeled excavators. It controls lift, tilt and auxiliary functions, so a worn spool shows up as a combination of drift, jerky movement and heat.

Measure drift properly: raise a loaded bucket, stop the engine, and time how far the bucket falls in one minute. Small movement is normal on a spool valve. Fast drop means internal leakage, and no amount of seal replacement will fix a scored spool bore.

Before ordering a valve, check pilot pressure, the accumulator charge and the joystick signal. Weak pilot pressure makes a healthy valve behave like a worn one, and it takes ten minutes to rule out. Also check the return filter for bronze: if the pump is already failing, a new valve will be contaminated within days.

Seal ring 11103242 for Volvo L110H / L120 / L150H / L220 loaders

Seal ring 11103242 and level sensor 21391689: small parts, expensive mistakes

11103242 seal ring is used on L110H, L120, L150H and L220 loaders. Iberian heat hardens nitrile seals quickly, and a weeping seal is easy to ignore until the oil film attracts abrasive dust and the joint starts to score.

Rule of thumb: wipe the joint dry, run one shift, then look again. A damp film after one shift is a leak, even if no drip reaches the floor. Replace seals in sets, never one at a time on a joint that carries pressure.

21391689 level sensor fits L110E, L110G, L110H, L105, L120G, L60F and L70F loaders. A failed sensor reads low when the tank is full, the operator tops up, the system overfills, oil foams and the machine overheats. Always confirm the gauge against the dipstick before replacing the sensor; a wiring fault at the plug produces exactly the same symptom.

Lead time and how to order into Spain and Portugal

We ship from Guangzhou to Madrid, Barcelona and Lisbon by air in 5 to 7 days, or by sea to Valencia, Algeciras and Sines in 26 to 32 days. A sensible stock package for a two loader quarry is one oil cooler, one set of brake discs, one control valve, a seal kit assortment and two level sensors.

Send machine serial number, photo of the old part nameplate and the symptom in one line. That is enough to confirm fitment the same day and to avoid shipping an L110F part for an L110H machine, which is the most common cross reference error on this platform.

Supply note: we supply aftermarket parts suitable for Volvo equipment, not genuine Volvo parts. Part numbers are used for cross reference and identification only. Confirm against the machine serial number and the old part nameplate before ordering.
