The Multiquip 2521110121 Main Bearing Cover Complete is a genuine OEM component designed for MT-74F, MT-74FA, MT-84F, MT-84FA, and MT74FAF series rammers. As a direct factory replacement, this cover assembly ensures the internal bearing components of your Multiquip tamper remain properly housed, sealed, and protected during operation. Sourced directly through authorized Multiquip distribution, part number 2521110121 is built to the same specifications as the original component installed at the factory. Confirm your model code against the fitment list before ordering to ensure a direct match.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip tolerances, ensuring the bearing bore geometry and sealing surfaces meet the same standards as the factory-installed cover.
- Direct Bolt-On Replacement — Matches the original mounting configuration on MT-74F, MT-74FA, MT-84F, MT-84FA, and MT74FAF rammers, allowing straightforward installation without machining or adaptation.
- Confirmed Rammer Fitment — Verified compatible across the MT-74F, MT-74FA, MT-84F, MT-84FA, and MT74FAF tamper models in the Multiquip rammer lineup.
- Bearing Protection — Keeps internal bearing assemblies properly enclosed, preventing contamination from dirt, debris, and moisture that can accelerate bearing wear and lead to crankcase damage.
- Structural Integrity — As a complete cover assembly, this part maintains the correct clamping load and alignment on the main bearing, which is critical to consistent stroke performance and machine longevity.
The main bearing cover on a rammer encloses and retains the crankshaft's main bearing assembly within the crankcase. It keeps the bearing correctly seated and shields it from external contaminants that would otherwise accelerate wear on the rotating components. When this cover cracks, warps, or loses its sealing integrity, the main bearing is exposed to debris and loses proper support — leading to increased vibration, irregular stroke, and ultimately crankshaft or crankcase damage if left unaddressed.
