Multiquip 04033100 Rod Bearing 0.5

The Multiquip 04033100 Rod Bearing 0.5 is a genuine OEM connecting rod bearing designed for MQ trash pump, MVH502DSB and MVH502DSB2 plate compactor, and MDR-9D power trowel applications. As a direct Multiquip OEM component, it is manufactured to the same tolerances and material specifications as the original bearing installed at the factory. This undersized 0.5 bearing is intended for use during engine reconditioning when the crankshaft journal has been reground to accept the increased bearing wall thickness. Confirm your model code against the fitment list — MQ trash pumps, MVH502DSB series compactors, and MDR-9D trowels — before ordering.

Key Features

• OEM-Grade Bearing Material — Manufactured to the same metallurgical and dimensional tolerances as the original Multiquip bearing, ensuring correct load distribution across the crankshaft journal.
• 0.5 Undersize Specification — Purpose-built for engines where the crankshaft has been reground 0.5mm undersize; drops directly into the reconditioned rod housing without additional machining.
• Broad Cross-Equipment Fitment — Compatible with MQ trash pumps, MVH502DSB and MVH502DSB2 heavy-duty reversible plate compactors, and MDR-9D mid-sized hydrostatic ride-on trowels.
• Protects Rebuilt Engine Longevity — A correctly sized rod bearing maintains the oil film between the connecting rod and crankpin; an incorrect fit accelerates journal wear and can lead to catastrophic engine failure.
• Critical Fuel and Ignition System Adjacency — Proper bearing clearance directly affects oil pressure; using the correct undersize specification during a rebuild safeguards the entire lubrication circuit on reconditioning.

The connecting rod bearing sits between the connecting rod big-end and the crankshaft crankpin journal, forming the critical interface that converts the piston's linear motion into rotational power. It relies on a thin pressurized oil film to prevent metal-to-metal contact during operation. When this bearing wears beyond tolerance or is fitted incorrectly during a rebuild, oil pressure drops, the crankpin journal suffers accelerated scoring, and the engine will ultimately seize. Using the correct 0.5 undersize specification — Multiquip 04033100 — during a crank regrind ensures that proper bearing clearance is restored and the reconditioned engine performs as intended.
