Core Advantages
Smooth Power Transmission
Precision-machined tooth profiles and tight tolerances ensure seamless power transfer from engine to transmission, eliminating jolts and vibrations during startup and load changes.
Shock-Resistant & Durable
Made of high-strength alloy steel with heat treatment, it can handle heavy loads and frequent impact forces. The anti-corrosion coating protects it from rust and wear, doubling its service life compared to generic couplings.
Direct OEM Fit, No Mods
Designed as a direct replacement for WA320-5/6/7 loaders - bolt it on without custom adjustments or extra parts, cutting installation time in half and getting your machine back to work fast.
Warning Signs, Installation & Maintenance
Time to Replace Your Coupling Assembly?
Abnormal vibrations or rattling noises when the loader is running
Sluggish power transmission, slow response when shifting gears
Visible wear, cracks, or deformation on the coupling teeth
Oil leaks around the coupling connection area
No-Fuss Installation Steps
Shut down the engine and disconnect the power supply for safety.
Remove the old coupling assembly, and clean the mounting surfaces of the engine and transmission.
Align the 419-12-31110 coupling with the shaft splines, and tighten the mounting bolts according to OEM torque specs.
Test-run the loader to check for abnormal noises or vibrations - if everything runs smoothly, installation is complete.
Maintenance Tips for Longevity
Inspect the coupling assembly monthly for wear, cracks, or loose bolts.
Apply lubricating grease to the spline connection every 500 working hours to reduce friction.
Avoid overloading the loader for extended periods, which can cause premature wear on the coupling.
Keep the coupling area clean and free of debris to prevent abrasive damage.
