The Multiquip 18045-501 is a genuine OEM Eccentric Crankshaft Assembly Gas Vibrator designed for the G55H gas-powered concrete vibrator. As a direct OEM replacement sourced through Multiquip's authorized parts network, this assembly is built to the same tolerances and specifications as the original component installed at the factory. Verified fitment for the G55H ensures this part installs correctly without guesswork, keeping your vibrator running the way it was engineered to perform.
Key Features
- OEM-Matched Eccentric Mass Tolerancing — Manufactured to the original eccentric weight and balance specifications, delivering consistent vibration frequency and amplitude output in the G55H.
- Direct Drop-In Replacement — Matches the original crankshaft assembly mounting points and dimensions, allowing straightforward installation into the G55H vibrator housing without custom fitting.
- Confirmed G55H Fitment — Verified compatibility with the Multiquip G55H gas concrete vibrator series for confident ordering.
- Restores Full Consolidation Power — A worn or damaged eccentric crankshaft causes erratic or reduced vibration output; replacing it with this OEM assembly restores the full compaction force needed for proper concrete consolidation.
- Genuine OEM Part Integrity — Sourced directly through Multiquip's authorized parts chain, this assembly meets the same material and machining standards as the original production component.
The eccentric crankshaft assembly is the core mechanical component responsible for generating the vibration in a gas-powered concrete vibrator. As the engine drives the crankshaft, the offset eccentric mass creates the rapid oscillating motion that is transmitted through the flex shaft and vibrator head into freshly poured concrete, consolidating the mix and eliminating air pockets. When the eccentric crankshaft wears, becomes damaged, or loses balance, vibration output becomes inconsistent or drops off entirely — resulting in poorly consolidated concrete, honeycombing, and structural weakness in the finished pour.
