Carburized to a depth of 1.0‑1.4 mm, the sleeve achieves extreme surface hardness while maintaining a tough core that absorbs shock loads without cracking.
Both internal and external splines are broached to Class 5 tolerance, ensuring a tight, backlash‑free fit with mating shafts and gears.
The sleeve design smoothly transfers torque between different spline sizes, minimizing stress concentrations and preventing fatigue failure.
Every sleeve is scanned for cracks; only defect‑free components receive the SINOTRUK stamp, guaranteeing reliability.
This transition sleeve is used to connect components with different spline profiles in the following SINOTRUK Howo driveline applications:
The WG2210100062 spline transition sleeve is a precision component that enables the connection of shafts and gears with differing spline specifications. It is manufactured from high‑quality 20MnCr5 alloy steel, which is first forged to near‑net shape, then precision machined and heat‑treated to achieve the optimal balance of surface hardness and core toughness. The internal and external splines are broached in a single setup, ensuring concentricity and accurate pitch spacing.
In heavy‑duty Howo transmissions, it is often necessary to connect components with different spline sizes or tooth counts. The WG2210100062 sleeve serves as an adapter, transmitting full engine torque without introducing excessive backlash. Its case‑hardened surface resists wear from fretting and micro‑movement, while the ductile core absorbs shock loads from sudden clutch engagement or rough terrain.
Installation of this sleeve requires careful attention to cleanliness and alignment. The sleeve should be slid onto the shaft with a light interference fit; heating the sleeve to 80‑100°C may be necessary for assembly. Ensure that the mating splines are free of burrs and lubricated with assembly oil. The sleeve must be fully seated against the shoulder, and any retaining rings or snap rings must be properly engaged.
Quality control for the WG2210100062 includes 100% dimensional inspection using coordinate measuring machines (CMM). Both internal and external splines are checked for lead, pitch, and tooth thickness. Every sleeve is subjected to magnetic particle inspection to detect any surface or subsurface cracks. Samples from each batch are tested on a torsional fatigue rig to verify durability under cyclic loads.
Environmental sustainability is considered in production. The steel is sourced from mills with ISO 14001 certification, and all machining scrap is recycled. The heat treatment process uses energy‑efficient furnaces with minimal emissions. At the end of its long service life, the sleeve is fully recyclable as steel scrap.
For transmission rebuilders and driveline specialists, the WG2210100062 spline transition sleeve is available individually or as part of a conversion kit. Each sleeve is packaged in a protective foam‑lined box to prevent damage to the precision‑broached splines during shipping. A data sheet with actual measured dimensions is included with each sleeve, providing full traceability.
Field performance data collected from over 250 heavy‑duty trucks shows that this sleeve has a mean time between failures exceeding 750,000 kilometers when properly maintained. Its robust construction and precise spline fit significantly reduce the incidence of spline wear and fretting corrosion, common issues with inferior aftermarket adapters.
When ordering, always verify the shaft and gear spline specifications. The WG2210100062 is specifically engineered for Howo applications with DIN 5480 splines. For other standards, consult the SINOTRUK parts catalog. Technical support is available through your local dealer – no contact details are listed here, in line with our policy.
In summary, the WG2210100062 spline transition sleeve represents the highest standard of quality and engineering for SINOTRUK Howo drivelines. Its case‑hardened splines, precision broaching, and rigorous inspection ensure reliable torque transfer and extended service life. Trust this genuine component to keep your fleet moving.
During driveline service, inspect the WG2210100062 sleeve for spline wear, pitting, or discoloration. Check that it fits snugly on the shaft without excessive play.
Use only the recommended gear oil. Ensure that splines are adequately lubricated during assembly to prevent galling.
Only the authentic WG2210100062 sleeve uses the exact steel grade and heat treatment specified by SINOTRUK. Imitations often use lower‑grade materials that wear quickly or have incorrect spline geometry, leading to backlash and driveline vibration. The genuine sleeve is 100% inspected and traceable to an ISO 9001 certified facility. Fleet data shows that OEM sleeves reduce spline‑related failures by 60%.
Preparation: Clean the shaft and sleeve bore thoroughly. Apply a thin coat of assembly lubricant to both spline sets. Inspect for burrs.
Assembly: Heat the WG2210100062 sleeve to 90°C and slide onto the shaft until seated against the shoulder. Secure with retaining ring. Verify free rotation.
After installation, check that the mating component slides smoothly into the external splines. Torque all fasteners to specification.
Precision‑matched splines minimize backlash, reducing driveline vibration and improving driver comfort.
The case‑hardened structure retains hardness up to 150°C, ensuring reliable performance in high‑temperature environments.
Steel contains >85% recycled content; 100% of machining scrap is recycled.
At end of life, the sleeve is 100% recyclable, supporting a circular economy.
Every WG2210100062 spline transition sleeve is laser marked with the part number for full traceability. When you order from our official distribution channel, you receive the latest production with optimized spline geometry for even better load distribution.
