The genuine OEM 381601182 Bronze Bushing (Py180g.13-5) is a precision-engineered wear component designed specifically for XCMG motor graders. This high-quality bronze bushing provides a low-friction bearing surface between moving parts, reducing wear and ensuring smooth operation in articulation joints, blade pivot points, and suspension systems of GR and PY series graders, delivering uncompromised reliability in the most demanding construction environments.
Manufactured to original XCMG specifications, the 381601182 bronze bushing is cast from high-grade bearing bronze with a hardness of 190-220 HBW, offering exceptional wear resistance and high compressive strength. It operates reliably from -40°C to +150°C and is designed to serve as a sacrificial wear interface, protecting expensive steel shafts and housings from metal-on-metal contact.
Using genuine XCMG 381601182 bronze bushings eliminates pivot point play, reduces friction, and prevents costly structural damage. Each component undergoes 100% dimensional inspection and hardness verification before packaging. Restore your grader’s articulation precision and mechanical smoothness with authentic OEM quality that matches the original equipment fitted at the XCMG factory.
The 381601182 bronze bushing is a critical component in XCMG motor grader pivot joints. It functions as a sleeve bearing between rotating shafts and stationary housings, absorbing radial loads and frictional heat generated during articulation, blade positioning, and suspension travel. By isolating these expensive components, the bushing acts as a sacrificial wear interface, preventing metal-on-metal contact that could lead to costly structural damage.
The bushing is manufactured from high-grade bearing bronze (CuPb10Sn10 / C93200 equivalent), a tin-bronze alloy with excellent wear resistance and high compressive strength. This material is specifically engineered to be slightly softer than the mating hardened steel shaft, ensuring that wear occurs primarily on the easily replaceable bushing rather than the expensive pin. This strategic design significantly reduces long-term maintenance costs and extends the service life of critical grader components.
Precision-machined oil grooves or pockets are integrated into the inner bore of the 381601182 bushing to retain grease and distribute it evenly across the contact surface. This establishes a hydrodynamic film that separates the metal surfaces during operation, drastically reducing wear rates and preventing galling. The outer diameter is ground to strict interference-fit tolerances, ensuring the bushing remains firmly seated in its housing without spinning, which is critical for joint stability and grader performance.
This bronze bushing directly replaces OEM part 381601182 (Py180g.13-5) on XCMG PY165G, PY170G, PY180G, PY200G motor graders, as well as GR135, GR165, GR180, GR215, GR300, GR350, and GR2405 series. The XCMG GR Series Motor Graders are essential construction machines for national defense engineering, mine construction, town and country roads building, and farmland improvement.
The 381601182 bronze bushing is typically installed in the articulation joint (frame pivot), blade lift cylinder pivot points, circle drawbar support, and front axle suspension linkage. These locations experience high cyclic loads, shock impacts, and constant relative motion, making high-quality bronze bushings essential for maintaining machine precision and operator safety.
Standardizing on genuine XCMG 381601182 bronze bushings reduces inventory complexity and ensures consistent wear performance across your fleet. Using genuine components eliminates pivot point play, restores mechanical smoothness, and prevents costly structural repairs. The GR series graders are widely used for ground leveling, ditching, slope scraping, bulldozing, scarification, and snow removal on highways, airports, farmlands, and mining areas.
Before installing the 381601182 bronze bushing, thoroughly clean the housing bore and inspect for burrs, scoring, or elongation. Measure the housing bore diameter and compare to the bushing outer diameter — the correct interference fit is essential for bushing retention. Apply a thin layer of anti-seize compound to the outer diameter and press the bushing into place using a hydraulic press or dedicated installation tool. Never hammer directly on the bushing, as this can distort the inner diameter.
After installation, align the grease groove with the lubrication port to ensure proper grease flow. Install the mating pin and check for smooth rotation. Lubricate the bushing with NLGI #2 lithium-based grease before initial operation. During scheduled maintenance (every 250 operating hours), re-grease the bushing and inspect for signs of wear, scoring, or excessive clearance.
If the bushing has worn beyond tolerance, replace it immediately. Signs of wear include excessive mechanical play (“slop”) in the pivot point, knocking or squeaking noises during articulation, or grease squeezing out too easily from one side. Delaying replacement can lead to pin damage, housing bore elongation, and costly structural repairs.
All 381601182 bronze bushings are manufactured in XCMG’s ISO 9001:2015 and IATF 16949 certified facilities. Each casting undergoes chemical composition verification (spectrometry), hardness testing (190-220 HBW), and dimensional inspection using CMM technology. Random samples are subjected to compressive load testing and accelerated wear testing to validate service life.
Full traceability from raw material ingot to finished bushing allows quality audits. XCMG provides a comprehensive 12-month or 2000-hour warranty against manufacturing defects. Batch traceability covers raw material certificates, heat treatment records, and final inspection documentation.
Counterfeit bronze bushings often use inferior alloys with incorrect hardness, leading to rapid wear, ovality, and premature failure. Genuine 381601182 bushings use certified high-grade bearing bronze with precise metallurgy validated by thousands of field hours. Aftermarket bushings may have incorrect dimensional tolerances, causing loose fits or seizure.

If you notice excessive mechanical play or “slop” in a pivot point, first measure the radial clearance with a dial indicator. If clearance exceeds 0.5 mm, the 381601182 bushing has worn beyond tolerance. Replace the bushing immediately to prevent pin damage and housing bore elongation.
If you hear knocking, clunking, or squeaking noises from articulation points, this indicates metal-on-metal contact due to lubrication failure or advanced wear. Inspect the grease grooves for blockage. Replace the bushing if the inner bore shows scoring or the outer diameter has spun within the housing.
If grease squeezes out too easily from one side of the joint during greasing, the bushing may have fractured or spun within its bore, blocking the grease channels. A spun bushing will quickly wear out the housing bore. Replace the 381601182 bushing immediately and inspect the housing for damage.
