The 980-307 Key is a precision‑ground square or rectangular key used to secure rotating components such as gears, pulleys, and sprockets to drive shafts. It fits into keyways machined into both the shaft and the mating part, transmitting torque without relying on friction alone.
A worn, sheared, or missing key can cause complete loss of power transmission, slipping, or catastrophic component damage. Replacing a damaged key with this OEM‑spec part restores reliable torque transfer and prevents further wear to shafts and hubs.
| Torque transmission | Transfers rotational force from shaft to mounted component |
|---|---|
| Alignment | Maintains precise angular alignment between shaft and hub |
| Prevents slippage | Eliminates reliance on friction only, preventing fretting and wear |
| Sheared / broken key | Key is split, cracked, or missing |
|---|---|
| Worn keyway | Key exhibits excessive wear or deformation |
| Slipping drive | Component slips on shaft under load |
| Vibration / noise | Unusual noise or vibration indicating loose drive component |
