Professional Installation Guide for Adjust Slack Adjuster
Safety First Protocol:
Park vehicle on level surface and securely chock all wheels
Engage parking brakes and completely depressurize air systems
Wear appropriate personal protective equipment
Follow all manufacturer safety guidelines and procedures
Installation Procedure:
Component Preparation: Thoroughly clean the brake camshaft splines using appropriate cleaning solutions. Inspect for wear, damage, or corrosion. Replace any compromised components before proceeding with installation.
Precise Alignment: Carefully align the 1-1/2″-28 spline of the adjust slack adjuster with the camshaft splines. Ensure perfect meshing without forcing components together to prevent damage to splines.
Secure Mounting: Slide the adjuster onto the camshaft until fully seated. Select appropriate arm length (5.0″, 6.0″, or 7.0″) based on vehicle specifications. Tighten the clamp bolt to manufacturer’s specified torque using a calibrated torque wrench.
Pin Connection: Install the 5/8″ pin, ensuring proper alignment and secure connection. Use new cotter pins and check for free movement without binding in all linkage components.
Initial Adjustment: Manually adjust the slack adjuster to take up slack until brake shoes contact the drum. Back off according to manufacturer specifications (typically 1/4 to 1/2 turn) to set proper running clearance.
Comprehensive Testing: Conduct thorough testing including:
Visual inspection of all connections and components
Air system pressure and leakage tests
Brake application and release tests
