The genuine XCMG 800106871 Turbine Shaft is a precision‑engineered powertrain component manufactured for XCMG GR series motor graders. This turbine shaft transfers rotational power from the torque converter turbine to the transmission input gears, enabling smooth, progressive acceleration and optimal torque multiplication during grading operations. Made from high‑alloy chromium‑molybdenum steel with induction‑hardened bearing journals, the 800106871 turbine shaft withstands extreme torsional stress, shock loads, and continuous high‑speed rotation encountered in heavy construction environments.
The 800106871 shaft integrates precisely machined spline ends on both sides – one side engages with the turbine hub inside the torque converter, while the other side meshes with the transmission’s input gear set. Dynamic balancing to ISO 1940 G6.3 ensures vibration‑free operation even at maximum engine RPM. The shaft is case‑carburized to a depth of 0.8–1.2 mm and hardened to 58–62 HRC on wear surfaces, while maintaining a tough, ductile core.
A cracked, twisted or worn turbine shaft can cause transmission slippage, erratic power delivery, and eventual drivetrain failure. Replacing a damaged shaft with genuine XCMG 800106871 restores original clearance tolerances and torque capacity, extending the life of your grader’s transmission and torque converter. Keep this critical component in your parts inventory to minimize costly unplanned repairs.

The 800106871 turbine shaft is the central link between the torque converter turbine wheel and the transmission input assembly. When the engine drives the converter pump, hydraulic oil spins the turbine, and the turbine transfers that rotational force through the splined shaft to the transmission. Any distortion or fracture of this shaft directly interrupts power delivery, causing imprecise movement of the grader blade and wheels.
On XCMG GR graders, this shaft operates in a high‑temperature ATF bath, often exceeding 100°C during heavy ripping or dozing operations. The induction‑hardened journals maintain dimensional stability and resist galling even under marginal lubrication. A worn turbine shaft will produce vibration, gear clash, and metallic debris in the transmission oil pan.
Failure to replace a fatigued shaft can result in complete turbine‑to‑transmission disconnection, leaving the grader immobile. Routine transmission overhauls (every 5,000 hours) should include magnaflux inspection of the 800106871 shaft for micro‑cracks. Install genuine XCMG to guarantee full power transfer and drivetrain longevity.
XCMG selects AISI 8620 chromium‑molybdenum alloy steel for its combination of core toughness and case hardenability. The shaft blank is forged to refine grain structure, then rough‑machined before carburizing. The carburizing furnace controls carbon potential at 0.85–0.95% C, with a cycle time of 8 hours to achieve uniform case depth of 0.9 mm on all spline flanks and bearing journals.
After carburizing, the shaft is quenched in agitated oil at 60°C, then double‑tempered at 180°C to convert retained austenite and relieve residual stresses. The resulting microstructure is fine‑grained martensite in the case with tempered martensite in the core, providing exceptional resistance to contact fatigue and plastic deformation.
Final operations include centerless grinding of the bearing journals to precision h6 tolerance, followed by superfinishing to a mirror‑like Ra 0.2 μm. Each 800106871 shaft is 100% eddy‑current tested for cracks and verified for spline geometry using a coordinate measuring machine. This ensures drop‑in fitment and zero premature failures.
Replacing the 800106871 turbine shaft requires removing the torque converter from the transmission housing. Drain ATF, disconnect driveline, and support the converter assembly on a dedicated stand. Unbolt the turbine hub and slide out the old shaft. Inspect the turbine hub splines for wear – if damaged, replace the turbine as well.
Before installing the new shaft, lubricate all splines with clean ATF and ensure the shaft rotates freely in the converter stator support bearing. Check end‑play using a dial gauge: acceptable range is 0.10–0.25 mm. If end‑play exceeds specification, inspect thrust washers and bearing preload. Tighten the turbine hub nut to 180 Nm (133 lb‑ft) using a torque wrench.
Always replace the front pump seal and transmission input gasket during this repair. After reassembly, fill with approved ATF, run the engine at idle, and check for leaks. Perform a stall test to verify torque converter performance. Keep a spare 800106871 shaft on hand for quick turnaround in case of transmission overhaul.
Aftermarket turbine shafts often use lower‑grade carbon steel with only surface hardening (shallow case depth 0.3 mm), causing spline wear within 1,000 hours. Many have incorrect spline geometry that accelerates wear on both the turbine hub and transmission input gear. Genuine XCMG 800106871 features full‑depth carburizing and precision grinding for ultimate durability.
Counterfeit shafts may lack proper dynamic balancing, leading to vibration that damages torque converter bearings and transmission seals. Some aftermarket parts have poor journal roundness (exceeding 5 microns), causing oil film breakdown and seizure. The genuine shaft is balanced to G6.3 and has journal roundness below 2 microns.
XCMG provides a 12‑month unlimited‑hour warranty. Each genuine 800106871 shaft is laser‑etched with a unique serial number and the XCMG logo. Investing in an OEM turbine shaft prevents catastrophic transmission failure and saves thousands in labor and towing costs. Always choose authenticity.
Typical indicators that the 800106871 turbine shaft requires replacement: vibrations felt in the cab during load, metallic particles on the transmission magnetic drain plug, difficulty engaging forward/reverse gears, and a whining noise from the torque converter area that changes with engine RPM. Also, any axial play exceeding 0.4 mm measured at the input shaft flange.
Preventive replacement is recommended every 6,000 operating hours or during any major transmission rebuild. The cost of a genuine shaft is trivial compared to a full transmission replacement (USD 8,000–12,000). During 1,000‑hour services, sample ATF for spectrographic analysis – elevated iron and chromium levels indicate shaft or spline wear.
Keep a stock of 800106871 shafts in your central warehouse. When rebuilding a torque converter, always install a new turbine shaft – the old one will have micro‑cracks from torsional fatigue. A well‑maintained drivetrain provides years of reliable grading performance without unexpected breakdowns.
