OEM WG2210100100 The spline sleeve is a critical chassis component that transmits torque from the transmission to the drive shaft while accommodating slight misalignments. The genuine SINOTRUK HOWO WG2210100100 Spline Sleeve is an OEM‑grade component engineered for a perfect fit and long‑term durability. As a vital element of the trusted Sinotruk howo parts family, this spline sleeve is crafted from high‑grade alloy steel to withstand extreme torque and vibration, restoring or enhancing driveline reliability efficiently. Its precision‑ground splines and robust metallurgy ensure smooth power transfer and extended service life.
The WG2210100100 is forged from 20CrMnTi, carburized to a case depth of 0.8‑1.2mm for exceptional wear resistance.
Splines are profile‑ground to DIN 5480 class 6e, ensuring backlash‑free engagement with the mating yoke.
Manganese phosphate coating with oil dip (MIL‑DTL‑16232G) prevents rust during storage and service.
Core hardness 32‑38 HRC provides toughness to absorb shock loads without cracking.

The spline sleeve connects the transmission output shaft to the drive shaft, transmitting full engine torque while allowing for slight axial movement. A worn or broken WG2210100100 sleeve can lead to driveline vibration, clunking noises, and eventual component failure. The genuine SINOTRUK HOWO sleeve is engineered with precise tolerances to maintain concentricity and prevent premature wear of mating parts.
The WG2210100100 is produced on CNC multi‑spindle lathes and profile grinders, ensuring every spline tooth is identical within 5 microns. Each sleeve is 100% inspected for dimensional accuracy.
Every batch undergoes magnetic particle inspection to detect surface defects, plus sample destructive testing for case depth and hardness. Only parts meeting Sinotruk specifications are released.
The development of the WG2210100100 Spline Sleeve focused on providing a durable and reliable connection under the most severe conditions. These sleeves are subjected to millions of torque cycles during the life of a truck and must maintain their integrity. A failed sleeve can cause expensive downtime. This genuine component is engineered to maintain its precision fit for hundreds of thousands of kilometers.
The metallurgy of the WG2210100100 starts with a seamless alloy steel tube. After rough machining, it undergoes gas carburizing at 920°C for 8 hours, then oil quenching and tempering. This creates a hard, wear‑resistant case while keeping the core tough. The splines are then profile‑ground to achieve a tolerance that minimizes backlash and distributes load evenly across all teeth.
Quality control for the WG2210100100 is exhaustive. In addition to 100% dimensional inspection, sample sleeves are tested for surface hardness, case depth, and core toughness. They are also subjected to axial fatigue testing to verify life expectancy. Only components that pass all these rigorous checks are approved for shipment as genuine Sinotruk Howo parts.
A failing spline sleeve can cause a range of issues. Symptoms include driveline vibration during acceleration, a clunk when engaging gears, or visible wear on the output shaft. During regular maintenance, the sleeve should be inspected for any signs of spline wear or corrosion. If any issues are found, immediate replacement with a genuine WG2210100100 sleeve is recommended to prevent damage to the transmission and driveshaft.
Installation is straightforward but requires attention to cleanliness. The old sleeve is removed, the splines are cleaned, and a thin layer of molybdenum disulfide paste is applied to the new WG2210100100 before sliding it onto the shaft. Ensure the retaining clip is properly seated.
Field performance of the WG2210100100 sleeve has proven its exceptional reliability. In a study of 200 Howo trucks operating in mining conditions, none showed signs of spline wear before 400,000 km. This reliability translates directly to reduced downtime and lower operating costs for fleet operators.
For parts managers, the WG2210100100 spline sleeves are available individually, each with a lot traceability label. Bulk orders (10+ units) receive additional packaging discounts and priority handling. The sleeves are packaged in VCI paper and foam‑lined cartons to prevent transit damage.
Warranty and support for the WG2210100100 are comprehensive. SINOTRUK HOWO provides a 2‑year/unlimited mileage warranty against manufacturing defects. Our technical support team is available via email to answer any questions regarding installation or compatibility, and we are committed to providing a response within 24 hours.
When ordering, always verify your transmission model and spline specifications. The WG2210100100 is specifically designed for Sinotruk Howo transmissions with 24‑tooth, 2.5 module splines. Using the correct part ensures a perfect fit and optimal performance.
In summary, the WG2210100100 Spline Sleeve is a vital component for ensuring the reliability and longevity of your SINOTRUK HOWO truck’s driveline. Its premium materials, precision manufacturing, and rigorous testing make it the preferred choice for spline sleeves. Trust the genuine WG2210100100 – it keeps your power flowing smoothly.
Inspect the spline sleeve during every transmission service. Look for wear on the spline teeth or corrosion. Always replace the sleeve if any damage is visible. Use only genuine WG2210100100 for replacement.
