💡 [ESSENTIAL PAIRING]:

🔧 Install Tips

Torque Spec: Check your GV300S manual for the specific Newton Meters (Nm). It’s a high torque setting (usually 80-100 Nm). Use a torque wrench.
Clean Threads: Ensure the engine shaft threads are clean before fitting to get an accurate torque reading.
Lock It Down: Once tightened, fold the edges of the new locking washer over the flat sides of the nut to prevent it from ever backing out.
