The 380900910 Tie Rod (steering linkage) is a genuine OEM steering component manufactured by XCMG for motor graders and heavy construction equipment. This precision‑forged tie rod, also known as a steering link or drag link, provides the critical connection between the steering gear and the front wheel knuckles on XCMG GR series motor graders. Constructed from high‑strength alloy steel with induction‑hardened ball joints, the 380900910 tie rod is designed to withstand extreme steering forces, vibration, and impact loads in demanding grading environments.
The tie rod 380900910 is a direct replacement for worn or damaged steering linkage on XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders. It features left‑hand and right‑hand threaded ends for precise toe‑in adjustment, sealed greaseable ball joints, and corrosion‑resistant zinc plating. Proper steering geometry depends on a rigid, correctly adjusted tie rod; a damaged or bent tie rod causes uneven tire wear, poor tracking, and reduced machine control.
Replacing a faulty tie rod with the genuine XCMG 380900910 restores original steering precision, eliminates play in the front axle, and extends tire life. Do not compromise safety with aftermarket alternatives – choose the OEM‑specified component engineered for your XCMG grader.

The XCMG 380900910 Tie Rod is a central component of the grader’s front axle steering linkage. It connects the left and right steering knuckles, ensuring both front wheels turn synchronously according to the driver’s input. Without a properly aligned tie rod, the front wheels would toe in or out incorrectly, causing erratic steering, excessive tire wear, and reduced grading precision.
On XCMG GR series graders, the tie rod 380900910 is subjected to extreme forces: steering cylinder thrust, ground reaction from uneven terrain, and impact loads when the front wheels strike obstacles. Its forged steel construction and induction‑hardened ball joints are designed to absorb these forces without bending or seizing.
A worn tie rod can be detected by excessive steering wheel play, uneven tire wear (particularly inner‑edge feathering), and a clunking noise when turning the wheel back and forth. Replacing a damaged tie rod with the genuine 380900910 restores factory steering geometry and eliminates these symptoms.
Each 380900910 tie rod begins as a solid alloy steel bar, which is forged into a dog‑bone shape with integral threaded ends. The forging process aligns the grain flow for maximum strength. After forging, the part is normalized to relieve internal stresses and then CNC machined to precise dimensions. The left‑hand and right‑hand threads are roll‑formed rather than cut, improving fatigue resistance by 40%.
The ball joints are assembled with a hardened chrome steel stud (58‑62 HRC) and a PTFE‑lined bearing shell, then sealed with a multi‑lip rubber boot. Each joint is greased at assembly with a high‑quality lithium complex grease. The assembled tie rod is then 100% tested for rotational torque, axial play, and thread conformity.
The finished 380900910 tie rod receives a zinc‑nickel plating that provides 480 hours of salt spray resistance. XCMG’s quality control includes magnetic particle inspection of the forging and eddy current testing of the threads. Only parts that pass all tests receive the coveted XCMG Genuine Parts label.
Replacing the tie rod 380900910 requires lifting the front axle and removing the front wheels. Loosen the lock nuts on each end of the old tie rod, then use a tie rod separator to disconnect the ball joints from the steering knuckles. Do not hammer the knuckle directly, as this can damage the taper bore.
Install the new tie rod 380900910 by inserting the ball stud tapers into the knuckles, then tightening the castellated nuts to 200 Nm. Install new cotter pins. Adjust the tie rod length by turning the center barrel so that the front wheel toe‑in is set to 2‑4 mm (measured at the wheel rim center height). Tighten the lock nuts to 300 Nm.
After installation, cycle the steering from lock to lock to check for binding. Grease both ball joints through their fittings. Perform a road test; the grader should track straight without steering wheel wander. Re‑check toe alignment after 50 hours of operation.
Aftermarket tie rods often use lower‑grade steel that bends under impact, or they have loose ball joints that quickly develop play. The genuine XCMG 380900910 is forged from 40Cr alloy steel and heat‑treated to achieve 900 MPa tensile strength, making it far more resistant to bending than generic alternatives.
Counterfeit steering linkage may have poorly cut threads that cross‑thread or gall, making toe adjustment impossible. The 380900910 features precision roll‑formed threads that turn smoothly and lock securely. Additionally, genuine XCMG ball joints have zero perceptible play when new, while aftermarket joints often have 1‑2 mm of free play that worsens within hours of operation.
XCMG provides a 12‑month warranty against manufacturing defects. Each tie rod is etched with the XCMG logo and part number. Using genuine parts ensures safety, predictable handling, and the longest possible service life. Don’t risk loss of steering control – choose the 380900910 genuine tie rod.
Common signs that the tie rod needs replacement include: steering wheel free play greater than 30 mm, abnormal front tire wear (feathering or scalloping), a clunking or popping sound when turning, and visible rust pitting on the tie rod barrel. If the grader pulls to one side despite correct tire pressures, the tie rod may be bent or the ball joints may be worn.
Preventive replacement is recommended every 5,000 operating hours or whenever the ball joints show radial play (excessive movement). Use a pry bar between the knuckle and tie rod to check for vertical play. If any movement is felt, replace the tie rod immediately.
Keep a spare 380900910 tie rod in your parts inventory for rapid field replacement. A failed tie rod can cause complete loss of steering, leading to serious accidents. Regular inspection and timely replacement with genuine XCMG parts is the only acceptable maintenance strategy.
