Key Features
- Genuine OEM Material Grade — Manufactured to the same hardness and dimensional tolerancing as the original, ensuring the key seats correctly under rotational load without slipping or deforming.
- Direct Drop-In Replacement — Sized to fit the existing keyway slot without machining or filing, allowing straightforward installation during shaft or pulley service.
- Broad Multiquip Fitment — Confirmed for V304, V305EH, V305EK, and FS1 series, covering walk-behind rollers and concrete saw applications in a single part number.
- Torque Transfer Integrity — A correctly fitted key square maintains positive power transmission between shaft and hub; a worn or missing key allows slippage that accelerates damage to both mating components.
- Drive Safety Assurance — Proper keying of rotating shafts prevents unexpected hub disengagement, which is critical on both compaction and cutting equipment where sudden loss of drive can create hazardous conditions.
A key square is a small, precision-cut metal block that fits into matching slots — called keyways — machined into both a shaft and the hub of a gear, pulley, or sprocket. Its purpose is to lock the two components together so that rotational force from the shaft is transmitted directly to the driven component without slipping. When a key square wears, shears, or goes missing entirely, the hub spins freely on the shaft, causing immediate loss of drive and potential damage to the surrounding keyway surfaces that can be costly to repair.
