The Multiquip MM434347 Crankshaft Bearing Set BLW-300 is a genuine OEM crankshaft bearing set designed for the BLW-300. As a direct OEM replacement, MM434347 is manufactured to the same tolerances and material specifications as the original component, ensuring correct clearances and a proper press fit within the crankcase. This bearing set is confirmed for BLW-300 equipment, so you can order with confidence knowing it is the right part for your machine. Sourced directly through authorized Multiquip supply channels, this is the same part that ships in new equipment — not an approximation.
Key Features
- OEM-Grade Bearing Precision — Manufactured to exact dimensional tolerances for the crankshaft journal, maintaining correct clearance and load distribution at operating speeds.
- Drop-In Crankcase Fit — Engineered to the original press-fit specification, allowing installation without machining or shimming adjustments.
- Confirmed BLW-300 Fitment — Verified for BLW-300 equipment; use part number MM434347 to confirm compatibility before ordering.
- Sustained Engine Integrity — Correctly spec'd crankshaft bearings prevent journal wear, oil film breakdown, and the vibration that accelerates damage to surrounding engine components.
- Genuine Multiquip OEM Part — Supplied through authorized Multiquip distribution, ensuring the part meets the same material and hardness standards as the original.
The crankshaft bearing set supports the crankshaft within the engine block, allowing it to rotate smoothly under the cyclical loads generated during operation. These bearings maintain the precise oil film clearance needed to prevent metal-to-metal contact between the crankshaft journals and the crankcase. When crankshaft bearings wear or fail, the result is increased vibration, abnormal engine noise, accelerated journal damage, and — if left unaddressed — catastrophic engine failure. Replacing them with a correctly toleranced OEM set like the Multiquip MM434347 restores proper crankshaft support and protects the engine's long-term serviceability.
