The 822138154 Hose (size φ25×270 mm) is a genuine XCMG hydraulic line specifically engineered for suction, return, and low-pressure applications on motor graders, wheel loaders, and heavy construction equipment. This precision‑manufactured hose assembly, designated as Hose φ25-270, features a 25 mm inner diameter (1 inch) and a total length of 270 mm between fitting faces. It is constructed from a synthetic rubber inner tube, multiple textile or steel spiral reinforcements, and an abrasion‑resistant outer cover. The 822138154 is designed to handle high-flow oil volumes in hydraulic tank suction lines, cooler return circuits, and filter bypass systems on XCMG GR135 through GR350 motor graders. Genuine XCMG 822138154 guarantees OEM fitment, superior kink resistance, and long service life in demanding grading environments.
The 822138154 is typically installed between the hydraulic tank and the main pump inlet, or as a low-pressure return line from the control valve to the oil cooler. Its large 25 mm bore minimizes flow resistance, preventing pump cavitation and reducing oil foaming. The hose is factory‑crimped with swivel or flanged end fittings, ensuring a leak‑free seal under vacuum or return pressure up to 1.5 MPa. Replacing a worn, collapsed, or leaking suction hose with genuine 822138154 restores full oil flow, protects the hydraulic pump from starvation, and extends component life.
A degraded suction hose can collapse internally, restricting oil supply and causing pump cavitation noise, overheating, and premature failure. The 822138154 features a rigid helix wire embedded in the wall to prevent collapse under vacuum, plus an oil‑resistant tube that withstands hot hydraulic fluid up to +120°C. Trust the OEM 822138154 to keep your motor grader’s hydraulic system healthy and productive.

The XCMG 822138154 Hose φ25-270 plays a vital role in ensuring adequate oil supply to the main hydraulic pump on GR series graders. It is most commonly used as the suction line between the hydraulic tank outlet and the pump inlet. Any restriction or collapse in this hose directly reduces pump flow, leading to cavitation, severe pump damage, and loss of implement speed. The 822138154’s large 25 mm bore and helix wire reinforcement guarantee unrestricted oil flow even under high-vacuum conditions.
This hose is also employed as a cooler return line from the control valve to the radiator-type oil cooler. Its short 270 mm length makes it ideal for compact installations where space is limited. The smooth inner tube and optimized bend radius prevent flow turbulence, reducing heat generation and pressure drop. Replacing a swollen or deteriorated return hose with genuine 822138154 restores proper cooling circuit performance.
A failing suction hose may exhibit symptoms such as pump whining noise, slow blade or circle response, and increased oil temperature. The 822138154 is designed with a steel helix spiral that fully resists collapse under vacuum, a common weakness of generic rubber hoses. By choosing genuine XCMG, you protect your hydraulic pump from starvation and avoid costly pump replacements (often exceeding $5,000).
Each 822138154 Hose φ25-270 is manufactured in XCMG’s dedicated hydraulic hose facility using high-precision extrusion lines and braiding machines. The inner tube is made from special NBR compound that resists hydraulic oil degradation and remains flexible at -40°C. Over the tube, two layers of high-tensile textile braid are applied, followed by a helix steel wire to provide vacuum resistance. Finally, a synthetic rubber cover is extruded and vulcanized for abrasion and ozone protection.
All end fittings are crimped using CNC‑controlled machines that apply 25 tons of force, ensuring consistent ferrule compression and leak‑proof connections. The crimp diameter is verified with digital calipers, and each assembly undergoes a 100% vacuum test (-0.09 MPa for 30 seconds) as well as a pressure proof test at 2.5 MPa. XCMG’s quality control also includes a 72‑hour heat aging test at +120°C and cold flexibility at -40°C.
The 822138154 is laser‑etched with the part number and production date for full traceability. Counterfeit hoses often omit the steel helix and use cheap rubber that hardens or cracks rapidly. Genuine XCMG hoses are backed by a 12‑month warranty and meet or exceed SAE 100R4 specifications. Protect your grader with the quality only XCMG can provide.
Replacing the 822138154 suction or return hose begins with draining hydraulic oil below the connection level or isolating the tank valve. Clean the area around both fittings to avoid dirt ingress. Using a backup wrench on the fitting hex, loosen the hose ends and remove the old assembly. Inspect the tank nipple and pump port for damage or old seal remnants. Always replace the sealing O‑rings or gaskets.
Position the new 822138154 hose so that it follows the original routing without sharp bends. The minimum bend radius for this hose is 125 mm – excessive bending can restrict flow and damage the helix wire. Hand‑tighten the fittings, then torque to specification: for M36 swivel ends, torque to 120 Nm; for flanged connections, use 50 Nm on bolts. After installation, fill the hydraulic tank and idle the engine while checking for leaks and listening for pump cavitation (should be quiet).
XCMG recommends inspecting the suction hose every 1,000 hours and replacing it at 4,000 hour intervals or sooner if cracks, bulging, or hardening are seen. Keep a spare 822138154 on hand to avoid extended downtime. Do not attempt to repair a damaged suction hose with tape or patches – always replace with genuine XCMG.
Aftermarket “universal” suction hoses often lack the embedded steel helix wire, leading to collapse under vacuum at higher engine speeds. This starves the pump of oil, causing cavitation damage and eventual pump seizure. The genuine 822138154 incorporates a full-coverage helix that maintains round cross‑section even at maximum vacuum. Aftermarket hoses also use lower-grade rubber that swells when exposed to hot hydraulic oil, reducing flow.
Many generic hoses have incorrect fitting orientations or crimp dimensions, making installation difficult and prone to leaks. The 822138154 is factory‑pre‑angled to match the exact port geometry on XCMG GR graders, saving installation time and eliminating stress on the hose. Additionally, counterfeit products often fail pressure and impulse tests, while genuine XCMG hoses are individually proof‑tested. Protect your grader’s heart – the hydraulic pump – with genuine 822138154.
XCMG provides a full 12‑month warranty against defects in materials and workmanship. Using genuine parts also preserves your machine’s resale value and ensures full compatibility with other OEM components. For fleet managers, the reliability of genuine 822138154 reduces unplanned downtime and maintenance costs over the long term. Insist on XCMG genuine.
Watch for these symptoms indicating the 822138154 hose needs replacement: visible cracks or bulges on the outer cover, a soft or flattened feel when squeezed, pump whining noise (cavitation), slow hydraulic implement response, and oil leaks at fittings. Also, if the hose feels hard and brittle, the rubber has degraded and should be replaced immediately.
During daily walk‑around inspections, visually examine the hose for chafing against frame members or other hoses. Listen for unusual pump noise at startup – a groaning sound often indicates a restricted suction line. If you see small cracks in the cover near the fittings, internal reinforcement may be corroded. Replace the hose at the first sign of deterioration.
Preventive replacement every 4,000 hours or three years (whichever comes first) is recommended for all hydraulic suction and return hoses. The cost of a genuine 822138154 is minimal compared to replacing a hydraulic pump (over $3,500) or cleaning up a major oil spill. Keep a log of hose replacements and always use OEM parts for critical suction circuits.
