OEM 800168878 The XCMG Water Transfer Tube 800168878 is a genuine OEM coolant tube engineered to carry engine coolant between the water pump and the cylinder block.
Identified by part number 800168878, this factory-formed tube completes the cooling circuit on XCMG hydraulic excavators and keeps flow steady.
It is produced from corrosion-resistant steel tube, mandrel-bent to the exact route, and fitted with correct end connections for a sealed fit.
Exact OEM length, bend radius, and port geometry allow direct replacement without cutting, welding, or adding adapters on site.
By keeping coolant flow sealed and unrestricted, this water transfer tube protects the engine from overheating and unstable temperature.
The 800168878 Water Transfer Tube is formed from seamless steel tube that resists rust, scale, and wall thinning in hot coolant service.
Mandrel bending keeps the bore round through every curve, so coolant flows without restriction, hot spots, or pressure loss.
Correctly formed end connections seal tightly against the pump and block ports, preventing coolant loss and air pockets.
The exact OEM route keeps the tube clear of belts, fan blades, exhaust heat, and moving parts in the engine bay.
A protective outer coating shields the tube from mud, coolant splash, and vibration rubbing that wears through bare metal.
Direct bolt-on dimensions mean the tube fits the first time, cutting diagnostic time and keeping machine downtime low.
Production begins with certified tube inspected for wall thickness, outside diameter, and material grade before bending starts.
CNC mandrel benders follow the XCMG drawing path, producing repeatable radii without flattening, wrinkling, or ovality.
End fittings are brazed or rolled under controlled conditions, then checked for penetration, squareness, and clean sealing faces.
Inspectors compare finished tubes against routing fixtures to confirm length, bend angles, and port positions match the machine.
Batch records let XCMG trace every 800168878 tube back to its tube lot and bending station, so quality questions are resolved quickly.
The water transfer tube carries coolant from the pump to the block, and it is a fixed part of the engine cooling loop.
A cracked or restricted tube starves the block of coolant, which raises cylinder head temperature and stresses the gasket.
The genuine 800168878 keeps the passage sealed and unobstructed, so the pump delivers full flow at every engine speed.
Correct routing away from heat sources prevents coolant boiling and bubble formation, which can stall the engine under load.
Stable engine temperature also keeps hydraulic oil cooler, which protects seals and maintains predictable machine response.
The 800168878 Water Transfer Tube installs with standard hand tools, keeping labour time and downtime low during service.
Let the engine cool completely, release cooling system pressure, and drain coolant to the level in the workshop manual.
Loosen the clamps or unions, remove the old tube, and clean both ports so old sealant and scale are fully removed.
Fit new seals or clamps where required, position the new tube along its original route, and tighten to the manual torque.
Refill with the specified coolant, run the engine to operating temperature, and check both connections for weeping.
During routine maintenance, check the tube for corrosion, rubbing marks, and loose clamps, and replace any suspect part early.
Every 800168878 tube is produced in an ISO 9001 and ISO 14001 certified facility with traceability from raw tube to packed carton.
Incoming tube is checked for grade and wall thickness, and finished tubes are measured for bend accuracy and union alignment.
During production, inspectors monitor bend angles and port positions against routing fixtures to keep tolerances tight.
Post-production checks include visual inspection, dimensional verification, and pressure testing of each brazed or rolled joint.
Sample tubes from every batch undergo vibration and thermal cycling to confirm they hold up under real engine conditions.
Inexpensive aftermarket coolant tubes often use thin tube, rough bends, or weak brazing that cracks and leaks within months.
The genuine 800168878 is manufactured to exacting XCMG standards, giving correct fit, reliable sealing, and long service life.
Its accurate forming and protective coating lower the risk of coolant loss, overheating, and unexpected engine shutdowns.
Genuine XCMG parts also preserve warranty coverage, protect resale value, and stay compatible with other OEM components.
Backed by XCMG global quality standards and technical support, this tube delivers dependable performance in tough conditions.
Selecting the genuine 800168878 tube stops small coolant seeps from becoming major engine failures on the job site.
A leaking or restricted transfer tube causes overheating, head gasket stress, and pump wear that escalates repair costs.
Durable steel and a proper coating keep coolant flow steady over a long service life, reducing how often the part is replaced.
Reliable coolant delivery also extends hose, seal, and oil life, lowering the total cost of ownership for fleet operators.
Fleet records from construction and mining operations show genuine XCMG cooling parts cut engine downtime noticeably.
XCMG applies sustainable manufacturing to the 800168878 tube through recyclable steel content and efficient bending processes.
A long service life reduces material waste and lowers the environmental footprint of replacement parts over the machine lifecycle.
Preventing coolant leaks protects soil and groundwater and supports compliance on environmentally sensitive construction sites.
Steel and coating materials in this component meet RoHS and REACH rules for safe handling and responsible disposal.
The 800168878 Water Transfer Tube is held in XCMG regional distribution centres across North America, Europe, Asia, and Australia.
Each tube is capped and wrapped in a protective sleeve inside a sturdy carton that guards against bending and impact.
For fleet-wide orders, XCMG provides volume pricing and consolidated freight options that simplify planning and reduce cost.
Real-time stock visibility and dedicated supply chain support help fill urgent requests quickly, shortening downtime on active projects.
Robust packaging preserves factory condition until installation, preventing the deformation that ruins spare tubes in storage.
The XCMG Water Transfer Tube 800168878 is a vital cooling system component for XCMG excavators, delivering coolant securely in demanding conditions.
Its seamless steel tube, mandrel-formed bends, and protective coating provide dependable performance in hot and dusty environments.
By stopping coolant leaks and flow restriction, this tube reduces downtime, lowers maintenance spending, and extends engine service life.
