OEM 319004422 The XCMG Auxiliary Oil Tank Housing (319004422) is a genuine OEM reservoir shell engineered to store and supply hydraulic oil on XCMG excavators. Identified by part number 319004422, this precision-formed steel housing maintains fluid capacity, resists pressure and vibration, and protects the hydraulic system in the toughest construction, mining, and quarry environments.
Manufactured from high-strength steel plate with a phosphate and primer coating, the 319004422 Auxiliary Oil Tank Housing offers outstanding structural rigidity, corrosion resistance, and long service life. Its exact OEM dimensions, port positions, and mounting pattern guarantee a direct replacement without modification.
By holding hydraulic oil securely, this housing prevents fluid starvation, reduces aeration, and helps the pump deliver stable flow to every circuit on the machine.
The 319004422 Auxiliary Oil Tank Housing is formed from high-strength welded steel that resists cracking under vibration and shock loading. This keeps the reservoir sealed through long working hours.
Internal baffle plates control oil movement during travel and swing operations. That reduces aeration and helps the pump draw clean, bubble-free fluid at all times.
Port faces are machined flat and parallel so suction, return, and breather flanges seal evenly. This detail prevents the slow weeping leaks that waste oil and stain the structure.
The phosphate and primer coating system resists chipping during installation. Even if a small area is scratched, the underlayer keeps corrosion from spreading across the plate.
By holding hydraulic oil securely, the 319004422 housing prevents fluid starvation and protects pumps, valves, and cylinders from cavitation damage.
Production begins with certified steel plate cut to size on computer-controlled equipment. Each blank is checked for thickness and flatness before forming begins.
Welding uses qualified procedures and certified operators. Every seam receives visual inspection, and sample joints are sectioned to confirm penetration depth.
After fabrication, each housing is cleaned and phosphated before priming and painting. Coating thickness is measured to ensure uniform corrosion protection.
Every unit is leak-tested with air pressure and then inspected for port alignment. Batch records allow XCMG to trace each housing back to its steel heat number.
The result is an auxiliary oil tank housing that performs predictably for thousands of hours on your XCMG excavator, season after season.
Hydraulic circuits depend on a steady supply of clean, bubble-free oil. The reservoir gives oil time to settle, release air, and dissipate heat before returning to the pump.
The 319004422 Auxiliary Oil Tank Housing provides dependable oil storage and stable fluid supply, preventing cavitation and protecting the pump from damage.
Field records from heavy excavation work show that machines fitted with genuine XCMG reservoirs suffer fewer hydraulic faults and shorter diagnostic sessions, improving availability.
The welded steel body and protective coating also resist moisture, dust, and chemical exposure, keeping performance stable across long service intervals in the field.
Inspect tanks regularly for seam cracking, coating loss, or weeping ports. Replace any compromised unit promptly with a genuine 319004422 component.
By keeping hydraulic oil contained and conditioned, this tank housing supports safe, productive excavator operation every working day.
The 319004422 Auxiliary Oil Tank Housing installs with standard lifting equipment and hand tools, which keeps downtime and labour costs low during service.
Park the excavator on firm level ground, lower the attachment, and release all hydraulic pressure. Lock out the machine so the engine cannot be started while work is in progress.
Drain the tank fully and disconnect the suction, return, and breather lines. Cap exposed openings immediately to keep grit and debris out of the hydraulic system.
Position the new housing on its mounts, install the fasteners finger-tight, then tighten to the specified torque. Fit new gaskets or O-rings and reconnect all lines.
Refill with clean hydraulic oil to the correct level. Run the machine at low idle and check every joint for weeping, then recheck the oil level after the system warms up.
During routine service, inspect the tank for cracks, corrosion, or seal damage. Replace any degraded component promptly to preserve hydraulic performance and avoid breakdowns.
Choosing the genuine 319004422 Auxiliary Oil Tank Housing pays back over time by preventing hydraulic leaks, cutting diagnostic hours, and eliminating downtime from failed reservoirs.
A cracked tank can drain the hydraulic system in minutes, pushing air through pumps, valves, and cylinders and converting a small repair into a complete system overhaul.
Across a typical 10,000-hour service life, the reservoir endures millions of pressure and vibration cycles. The welded steel body of the 319004422 keeps performance consistent throughout.
Reliable oil storage also extends the life of connected components such as pumps, valves, and cylinders, reducing replacement frequency and total maintenance spending.
Field data gathered from large mining and construction fleets shows genuine XCMG reservoirs cut hydraulic-related downtime by as much as 16 percent.
The durable construction and quality coating keep the housing serviceable for years, removing the need for premature replacement and lowering lifecycle costs.
XCMG applies sustainable manufacturing principles to the 319004422 Auxiliary Oil Tank Housing through recyclable steel content and energy-efficient production processes.
The extended service life, often exceeding 10,000 hours in normal conditions, cuts material waste and lowers the environmental footprint associated with frequent replacements.
Preventing hydraulic leaks also avoids secondary damage and soil contamination, which supports regulatory compliance and responsible environmental stewardship on job sites.
Steel and coating materials are free from restricted heavy metals and comply with RoHS and REACH rules, ensuring safe handling and disposal at end of life.
Selecting genuine XCMG hydraulic components supports responsible equipment management while delivering superior operational reliability and safety.
The precision-engineered design allows long, dependable service, which minimises resource consumption and waste generation across the machine’s working life.
