OEM 800167138 The XCMG 4927631 Oil Supply Line 800167138 is a genuine OEM oil feed line engineered to deliver pressurized engine oil to the turbocharger on XCMG hydraulic excavators.
Registered under part number 800167138, this oil supply line maintains a stable, unrestricted oil flow between the engine block and the turbocharger bearing housing.
The line is formed from seamless steel tubing with precision flared or banjo end fittings, and a corrosion-resistant surface treatment that resists heat and oil degradation.
Identical OEM bore diameter, fitting thread and routing geometry mean the oil supply line installs directly during repair, with no bending or adapters required.
By supplying clean, pressurized oil without restriction, this oil supply line protects the turbocharger bearings from seizure, wear and catastrophic failure.
The 800167138 oil supply line is formed from seamless steel tubing that resists internal pressure, vibration and continuous thermal cycling.
A smooth bore minimizes flow restriction so the turbocharger receives the full oil volume required for bearing lubrication and cooling.
Identical OEM bore diameter, fitting thread and routing geometry allow a direct replacement without bending, which means faster installation.
Precision-formed end fittings provide a secure, leak-free connection that holds oil pressure under the most aggressive machine vibration.
A zinc-plated finish shields the line from rust and chemical attack, extending service life in hot, dusty and humid environments.
Because this is a genuine XCMG component, it preserves warranty coverage and maintains full compatibility with other OEM parts.
Production begins with certified seamless steel tube that is inspected for wall thickness, ovality and surface quality before release.
Tube bending is performed on computer-controlled mandrels that hold bore diameter, bend radius and routing geometry within exact tolerances.
End fittings are machined and attached using controlled processes, then each line is cleaned, deburred and checked for internal contamination.
Batch records allow XCMG to trace every 800167138 oil supply line back to its raw material lots, so any quality question can be answered quickly.
Sample lines from each production batch undergo pressure testing, vibration testing and corrosion testing to confirm long-term durability.
The oil supply line carries pressurized oil from the engine block to the turbocharger bearing housing, where it lubricates and cools the shaft bearings.
The 800167138 oil supply line maintains a stable oil flow at both low idle and full load, keeping the turbocharger bearings properly supplied.
Stable oil flow protects the turbocharger from bearing seizure, shaft scoring and catastrophic failure that can destroy the entire engine.
By preventing leaks and blockages, the line also reduces oil consumption and keeps the machine working efficiently on site.
When the oil supply line performs correctly, the engine holds oil pressure and the machine frame experiences less vibration and stress.
Inspect the line during routine service for cracks, chafing or loose fittings, and replace any worn unit with a genuine 800167138 oil supply line.
The 800167138 oil supply line installs with standard hand tools, which keeps downtime and labour costs low during repair work.
Park the excavator on firm level ground, shut down the engine, and allow the system to cool and drain before starting work.
Remove the old oil supply line, inspect the engine block and turbocharger ports for damage, and clean all contact surfaces.
Position the new oil supply line along the original routing, align the fittings, and hand-thread the banjo bolts or flare nuts into place.
Tighten the fittings to the specified torque, ensuring the line is not twisted, stressed or touching hot or moving components.
Start the engine at low idle, check for leaks at both fittings, and confirm correct oil pressure before returning the machine to service.
Choosing the genuine 800167138 oil supply line pays back over time by preventing oil starvation and turbocharger damage.
A cracked or clogged oil supply line causes oil loss and turbo bearing seizure, which lead to costly repairs to the turbo and engine.
The durable steel construction of this line keeps oil flow consistent over a long service life, reducing replacement frequency.
Reliable oil supply also extends the life of connected parts such as the turbocharger, oil pump, cooler and engine bearings.
Field data from large construction and mining fleets shows genuine XCMG engine components reduce lubrication-related downtime significantly.
The line remains serviceable for years under normal conditions, removing the need for premature replacement and lowering inventory costs.
XCMG applies sustainable manufacturing principles to the 800167138 oil supply line through recyclable steel content and energy-efficient processes.
Extended service life, often exceeding 10,000 hours in normal conditions, cuts material waste and lowers the environmental footprint.
Preventing leaks also avoids oil loss and soil contamination, which supports regulatory compliance and responsible site management.
Materials used in this oil supply line are free from restricted substances and comply with RoHS and REACH rules for safe disposal.
Selecting genuine XCMG engine components supports responsible equipment management while delivering superior operational reliability.
The precision-engineered design allows long, dependable service, which minimises resource consumption across the working life of the machine.
The 800167138 oil supply line is stocked in XCMG regional distribution centres across North America, Europe, Asia and Australia.
Every unit is capped, wrapped with protective film and packed in a fitted carton, shielding the line from impact, moisture and contamination.
For fleet-wide orders, XCMG offers volume pricing and consolidated freight options that reduce procurement costs and simplify inventory planning.
Real-time stock visibility and dedicated supply chain support help fulfil urgent requests quickly, shortening downtime and keeping excavators productive.
Sturdy packaging preserves the factory condition of the line until installation, preventing damage that often occurs with poorly stored spare parts.
With the XCMG global aftermarket network behind it, you can depend on consistent quality and availability to keep your fleet at full capacity.
Every 800167138 oil supply line comes from an ISO 9001 and ISO 14001 certified plant with full traceability from raw stock to packed product.
Incoming steel tube is tested for chemical composition, tensile strength and dimensional accuracy before release to production lines.
During manufacturing, bore diameter, wall thickness, bend radius and fitting thread dimensions are monitored continuously by trained operators.
Post-production checks include pressure testing, leak testing and dimensional verification to confirm that each line meets specification.
Sample lines from each batch undergo vibration testing and corrosion testing to prove long-term durability and stable oil flow performance.
Only lines that pass every quality gate are released, so you receive a dependable, high-performance engine component every time you order.
Cheap aftermarket oil supply lines often use thin walls, inaccurate fittings or poor routing that lead to leaks and oil starvation.
Those shortcuts create oil pressure loss, turbo bearing damage and unreliable performance in demanding construction and mining conditions.
The genuine 800167138 is built to exacting XCMG standards, delivering correct fit, stable oil flow and durable performance on site.
