Key Features
- OEM-Matched Dimensions — Machined to exact tolerances for correct shaft and hub engagement, ensuring the key seats fully without play or binding.
- Genuine Multiquip Part — Sourced directly from Multiquip as an authorized OEM component, not an approximated substitute.
- Direct-Fit for MVH304GSB — Confirmed fitment for the MVH304GSB reversible plate compactor; part number 457010090 is the verified OEM reference for this model.
- Torque Transfer Integrity — A correctly fitted crescent key locks rotating components in precise alignment, maintaining full power transmission from engine to eccentric assembly.
- Prevents Slippage and Component Damage — A worn or missing key allows shaft components to rotate independently, causing rapid wear to mating surfaces and potential drivetrain failure.
A crescent key — also known as a Woodruff key — is a small, semi-circular metal component that fits into matching keyways cut into a shaft and hub. Its role is to lock the two components together rotationally, ensuring torque is transferred cleanly without slip. On a reversible plate compactor like the MVH304GSB, this type of key is commonly used to secure drive pulleys, eccentric shafts, or engine output components. When a crescent key shears or wears, the connected components lose their rotational lock, leading to vibration irregularities, accelerated wear on the keyway, and ultimately loss of compaction force or drivetrain damage.
