The genuine XCMG 800106960 Auxiliary Drive Shaft is a precision‑engineered powertrain component designed for XCMG GR series motor graders. This OEM auxiliary shaft transfers mechanical power from the transmission or transfer case to driven accessories such as hydraulic pump drives, fan drives, and other PTO (power take‑off) systems. Manufactured from high‑strength alloy steel (42CrMo4) with induction‑hardened bearing journals and precision‑ground splines, the 800106960 auxiliary drive shaft delivers reliable torque transmission under continuous heavy‑duty operation. Typical applications on GR135, GR165, GR180, GR215, GR260, GR300, GR350, and GR2003 graders include powering the main hydraulic pump, steering pump, and charge pump for the hydrostatic transmission.
The 800106960 shaft features multiple splined ends and ground bearing seats, allowing it to mesh seamlessly with both the internal spline of the drive gear and the pump coupler. The shaft is balanced to ISO 1940 G6.3 quality grade, ensuring vibration‑free operation up to 3,500 rpm. The material is through‑hardened to 38–42 HRC on the core, with induction hardening on wear surfaces reaching 55–60 HRC. This dual‑hardness design provides toughness to withstand torsional shock loads while offering superior wear resistance at splines and journal interfaces.
A cracked, twisted, or worn auxiliary drive shaft will cause loss of hydraulic power, erratic pump operation, and potential damage to the transmission housing. Replacing a damaged shaft with genuine XCMG 800106960 restores original driveline geometry, eliminates play, and ensures all auxiliary systems receive full power. Keep this critical component in your parts inventory to avoid costly downtime during grader operation.

The 800106960 auxiliary drive shaft is the mechanical link between the grader’s transmission/transfer case and the hydraulic pump stack. Without this shaft, the main hydraulic pump would not rotate, and critical systems such as blade lift, circle rotation, steering, and brakes would be inoperable. The shaft transmits up to 950 Nm of torque directly to the pump input shaft, ensuring full flow and pressure.
On XCMG GR graders, this shaft is also used to drive the hydraulic charge pump for the hydrostatic transmission. A failure of the auxiliary shaft will cause immediate loss of hydrostatic drive, leaving the machine immobile. Additionally, the shaft drives a cooling fan motor on some models, preventing engine overheating. Proper spline engagement and journal concentricity are essential for vibration‑free operation.
Typical failure modes include spline wear (caused by insufficient grease or misalignment), shaft twist from repeated shock loading, and fatigue cracks originating from keyways or stress risers. Regular inspection during transmission overhauls is recommended. Replacing a suspect shaft with genuine 800106960 eliminates hidden cracks and restores original power transmission efficiency.
XCMG selects 42CrMo4 alloy steel for its excellent hardenability and toughness. The shaft blank is hot‑forged to refine grain orientation, then normalized to relieve forging stresses. CNC turning and spline hobbing are performed after soft machining. The splines are cut to DIN 5480 standards, ensuring perfect mating with OEM pump couplers.
The shaft undergoes through‑hardening by austenitizing, oil quenching, and tempering at 550°C, achieving a uniform core hardness of 38–42 HRC. Then, selective induction hardening is applied to the bearing journals and spline flanks, raising surface hardness to 55–60 HRC with a case depth of 1.5 mm. This provides a hard, wear‑resistant surface while maintaining a tough, shock‑absorbing core.
After hardening, the journals are centerless ground to precise h6 tolerance and superfinished to Ra 0.2 μm. The shaft is then dynamically balanced on a Schenck machine, with residual unbalance less than 2 g·mm. Each 800106960 shaft is 100% magnaflux inspected for surface cracks and verified for spline dimensions using an optical comparator.
To replace the auxiliary drive shaft, first drain the transmission or transfer case oil. Remove the PTO cover and disconnect the pump driveshaft. Support the pump assembly to avoid overhanging load. Use a puller to remove the old shaft, being careful not to damage the housing or bearings. Inspect the housing bore for scoring or ovality.
Lubricate the splines and bearing journals with clean transmission fluid. Insert the new 800106960 shaft, engaging the internal spline of the drive gear. Rotate the shaft slightly to align splines. Install new snap rings and thrust washers as per the service manual. Torque the retaining bolt (if present) to 120 Nm (89 lb‑ft).
Before reinstalling the pump, check the shaft end‑play using a dial gauge; acceptable range is 0.05–0.15 mm. If end‑play is out of specification, adjust shims accordingly. After final assembly, refill with approved oil, run the engine at idle, and check for unusual noise or vibration. Keep spare 800106960 shafts in your central parts store to support emergency field repairs.
Aftermarket auxiliary shafts often use lower‑grade 1045 carbon steel without induction hardening, leading to rapid spline wear within 500 hours. Many have poor spline geometry that accelerates wear on the mating pump coupler. Genuine XCMG 800106960 uses induction‑hardened 42CrMo4 for long spline life and proper fit.
Counterfeit shafts may lack dynamic balancing, causing vibration that destroys bearings and seals in the pump and transmission. Some have incorrect journal diameters (oversized or undersized), resulting in either loose fit (shaft whip) or interference fit that seizes bearings. Genuine parts are precision ground and balanced to factory specifications.
XCMG provides a 12‑month unlimited‑hour warranty against manufacturing defects. Each genuine shaft is laser‑etched with the 800106960 part number and production lot code. Using OEM components protects your grader’s transmission and hydraulic pumps – the cost of an aftermarket failure far exceeds the price of a genuine shaft.
Common symptoms of a failing auxiliary drive shaft: audible clicking or grinding noise from the PTO area, vibration felt in the cab when the hydraulic system is under load, metal particles in the magnetic transmission drain plug, and intermittent loss of hydraulic pump pressure. Also, difficulty in removing the shaft during maintenance indicates spline galling.
Preventive replacement is recommended every 4,000 operating hours or during any transmission rebuild. The cost of a genuine shaft is negligible compared to the damage caused by a snapped shaft – which can destroy the transmission housing and require a full replacement (over USD 10,000). During every 1,000‑hour service, inspect the PTO area for oil leaks and unusual noise.
Keep a stock of 800106960 shafts in your fleet warehouse. When replacing bearings or seals in the auxiliary drive housing, always install a new shaft – the old one will have micro‑cracks from torsional fatigue even if visually acceptable. A proactive replacement strategy minimizes unplanned downtime and extends grader life.
