OEM 319002591 The XCMG Hydraulic Oil Cooler 319002591 is a genuine heat exchanger that removes heat from the hydraulic oil before it returns to the tank and pump.
Issued under the official part number 319002591, the cooler gives the technician a correctly sized unit that matches the mounting brackets, hose ports and airflow path it is designed for.
The core and tanks are brazed to the XCMG drawing, so the fin pitch, tube spacing and port positions line up with the chassis without cutting or re-piping.
A matched fin and tube design keeps the oil cool under load, so the hydraulic system stays at a safe working temperature.
A protective coating and corrosion-resistant core resist oil, water and dust, so the cooler keeps its performance through wash-down and long outdoor duty.
Every unit is pressure tested for leaks and checked for port position, fin quality and mounting dimensions before shipment.
Fitted to the return circuit and fan-assisted cooling pack, this cooler keeps oil viscosity stable and protects pumps, valves and seals.
The 319002591 cooler is produced to the XCMG drawing, so the ports and mounting brackets line up with the chassis on the first attempt.
A matched fin and tube design keeps the oil cool under load, so the hydraulic system stays at a safe working temperature.
Brazed joints are pressure tested, so the core does not weep oil at the seams or at the port bosses.
A corrosion-resistant core and coating resist water, dust and wash chemicals, so the cooler does not clog or rust through.
Because the part matches the OEM number, a fitter installs it straight from the crate without cutting, bending or adding adapters.
Correct core thickness keeps airflow steady, so the fan pulls air through the fins and cools the oil efficiently.
A sound cooler also protects seals and hoses, because oil that stays cool does not harden or degrade them quickly.
Keeping a spare cooler on the shelf shortens repair time, so a clogged unit does not turn into a full day of lost work.
Each lot begins with certified aluminum fin stock and tube tested for thickness, strength and brazing quality before assembly.
Cores are brazed in controlled furnaces, so the fin pitch, tube spacing and tank joints stay uniform from batch to batch.
Cleaning and finishing remove flux and burrs, so the cooler does not carry debris into the oil circuit after installation.
Inspectors measure core size, port positions, fin pitch and mounting hole spacing against a gauge for this exact part number.
Batch records trace every 319002591 cooler to its material lot and production run, so a quality question is settled quickly.
A hydraulic oil cooler removes heat from the return oil, so the system stays within its design temperature range.
A clogged or leaking cooler lets the oil overheat or escape, which thins the oil and wears pumps and seals quickly.
The genuine 319002591 keeps the oil cool and contained, so viscosity holds and internal parts stay protected.
Correct fit avoids both a cooler that rubs on a bracket and one that sits too close to a hot or moving part.
A sound cooler protects pumps, valves and cylinders, which keeps service intervals predictable and extends machine life.
The 319002591 cooler is installed with a cleaning cloth, a spanner set and lifting gear during hydraulic service work.
Release system pressure, drain the affected lines and cap the ports so no dirt or metal chips enter during the repair.
Check the brackets, hoses and mounting faces for cracks, rust or damage, since a bad mount will stop the cooler sitting flat.
Lift the cooler into place, start the mounting bolts by hand and reconnect the hoses before tightening.
Tighten to the torque in the service data, so the cooler stays put without crushing the tanks or stripping the thread.
Refill with the specified oil, run the machine slowly and check the seams and ports for weeping after the first cycles.
At service intervals, clean the fins and look for oil film, bent fins or a cracked tank before the cooler loses performance.
Every 319002591 cooler is produced in an ISO 9001 and ISO 14001 certified plant with traceability from core to carton.
Incoming material is tested for strength and thickness, and finished coolers are gauged for core size, port position and mounting holes.
Each batch is screened for brazing voids, fin damage and coating defects, since these flaws cause leaks or reduce cooling.
Post-production checks include visual review, dimensional verification and a pressure leak test on every unit.
Sample coolers from each batch undergo burst, vibration and salt spray tests to confirm strength and corrosion performance.
Cheap copies often use thin fins and poor brazing, so the cooler leaks, clogs or loses cooling capacity soon after installation.
A cooler with the wrong port positions or core size can rub a hose, starve airflow or fail to fit the mounting brackets.
The genuine 319002591 is made to the XCMG drawing, so core, ports, brackets and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM cooling packs.
Backed by XCMG global quality standards and technical support, this oil cooler performs reliably in harsh conditions.
Choosing the genuine 319002591 cooler prevents a small weep from turning into a damaged pump or a seized valve.
A failed cooler lets oil overheat and escape, which thins the oil and shortens component life across the circuit.
A correctly made cooler holds pressure and cools firmly, so it does not need repeated repair and does not leak between services.
Reliable coolers also keep oil temperature stable, which improves machine performance and lowers ownership cost.
Service records from construction and mining fleets show genuine XCMG parts cut unplanned downtime.
XCMG produces the 319002591 cooler with efficient brazing and assembly runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each cooler.
Containing hydraulic oil prevents leaks and contamination, which protects soil, groundwater and internal parts.
The materials in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 319002591 cooler is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each unit is wrapped to protect the core and boxed or palletised in strong packing that guards against dust, damp and impact.
Fleet buyers can request volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams cover urgent requests fast, so machines return to work sooner.
Careful packing keeps the fins straight and the ports undamaged until fitting, avoiding the distortion seen in loose storage.
