Steering shaft sleeves are crucial components in maintaining steering system rigidity and smooth operation. They are subjected to continuous torsional forces during turning and relentless vibration and road shock. While the joint must be structurally sound for safety, the component must be serviceable for repairs to the steering column, demanding a locking solution that allows for removal.
The optimal solution is a retaining compound engineered for structural holding power while offering the lowest strength for serviceability.
INCURE WeldLock™ 338 Retaining Compound (Yellow)
The INCURE WeldLock™ 338 Retaining Compound is the functional “Medium Strength” solution. It is designed for press or slip-fit applications where future disassembly is required, providing excellent security against vibration without making future steering column service a destructive process.
| Key Feature | Performance for Steering Shaft Sleeves |
| Serviceable Bond (Yellow) | Specifically designed for assemblies requiring removal or repositioning. Locks the sleeve securely against vibration and torque, but allows for non-destructive removal during maintenance. |
| Excellent Vibration Resistance | Provides reliable holding power against continuous road shock and engine vibration, preventing the sleeve from shifting or rattling. |
| Gap Fill (Up to 0.25mm) | Effectively fills the annular space, eliminating play that could lead to slop in the steering feel and premature wear. |
| Temperature Resistance (150∘C) | Maintains integrity under standard vehicle operating temperatures. |
Application Steps: Installing Steering Shaft Sleeves
For optimal performance and reliable retention of the steering shaft sleeve, follow these steps:
1. Surface Preparation (The Foundation)
- Clean: Thoroughly clean both the steering shaft surface and the sleeve bore. Surfaces must be free of all grease, oil,and residue. Use an industrial cleaner or solvent (e.g., acetone) and wipe dry.
- Activate (If Needed): If using passive metals (like stainless steel or plated parts) or if the ambient temperature is below 15∘C (59∘F), apply a chemical activator to the bond surfaces and allow it to flash off completely.
2. Product Application
- Apply: Apply a continuous, thin bead of WeldLock™ 338 around the full circumference of either the shaft or the internal bore of the sleeve.
- Ensure Coverage: For optimal retention, ensure the adhesive completely wets the entire mating surface as the components slide together.
3. Assembly and Curing
- Assemble: Immediately slide or press the sleeve onto the shaft. Ensure the components are aligned correctly before the compound fixtures.
- Wipe Excess: Remove any excess adhesive visible outside the joint immediately after assembly.
- Cure: Allow the assembly to fixture before handling (typically 10-30 minutes). Allow a full 24 hours for the compound to reach maximum strength before returning the vehicle to service.
