Products Description
The HD90149340019 is a right rear brake adjusting arm for SHACMAN F3000/X3000 (drum brake systems). We've sold it to 30+ repair shops and fleets for 5 years-everyone says it's steady: no adjustment failure, no mechanism wear, no brake drag.
It has forged steel arm body (high-strength), alloy steel adjusting worm gear (wear-resistant), and zinc-plated rust-proof surface. Daily use, vibration, brake pressure, rain, dust, -30℃ to 80℃-none mess it up. It adjusts brake shoe-drum clearance, keeps braking efficient, fits SHACMAN's right rear brake perfect: remove old arm, install direct, no extra work. We test torque resistance, wear resistance, corrosion resistance, so it's reliable.
Features And Advantages
① Precise adjustment: Alloy steel worm gear adjusts clearance accurately-consistent braking, no weak brake or drag.
② Durable & rust-proof: Forged steel resists deformation; zinc-plated stops rust. Sealed mechanism keeps dust out, lasts ≥4 years.
③ Fits SHACMAN fast: Mounts, pins, interface match original brake. Fasten bolts, connect linkage-easy install, saves time.
④ Stable operation: Optimized structure reduces stress; worm gear self-locks, no clearance changes from vibration.
Application Scope
Only SHACMAN F3000/X3000 (drum brake; right rear brake). No SHACMAN disc brake trucks or other brands (HOWO)-different brake specs, can't fit.
