The Multiquip 04001900 Big End Bearing is a genuine OEM component designed for MVH502DSB2 and MVH502DSB plate compactors, MDR-9D power trowels, and MQ41TDH trash pumps. As a direct factory replacement, this bearing is manufactured to the exact tolerances required by Multiquip equipment, ensuring correct fit without modification. Sourced directly through authorized channels, the part is the same part shipped on new machines from the factory. Confirm your model code before ordering to ensure full compatibility with your specific unit.
Key Features
- OEM-Grade Bearing Tolerancing — Manufactured to Multiquip's exact dimensional and load specifications, ensuring the connecting rod seats and rotates correctly under operating stress.
- Drop-In Replacement — Engineered to install directly into the original bearing journal position with no machining or adaptation required, preserving correct crankshaft geometry.
- Broad Cross-Equipment Compatibility — A single OEM part number covering the MVH502DSB2 and MVH502DSB plate compactors, MDR-9D power trowel, and MQ41TDH trash pump.
- Sustained Power Transfer — A correctly functioning big end bearing keeps the connecting rod rotating smoothly around the crankshaft journal; a worn bearing causes knock, vibration, and rapid engine damage.
- Critical Engine Safety Boundary — Bearing failure in reciprocating equipment can result in connecting rod separation and catastrophic engine damage; replacing at first sign of wear is essential to safe continued operation.
The big end bearing sits at the large end of the connecting rod, wrapping around the crankshaft journal to convert the crankshaft's rotational motion into the reciprocating stroke that drives compaction, troweling, or pumping action depending on the host machine. It operates under high cyclical load and must maintain a precise oil film clearance to prevent metal-to-metal contact. When this bearing wears, operators typically notice increased engine knock or vibration; left unaddressed, bearing failure can lead to a seized or destroyed crankshaft assembly.
