The Multiquip 9122746080 Metal Set -0.50MM is a genuine OEM bearing metal set designed for DCA40SSAI, DCA60SSAI, and DCA40SSI ultra-silent diesel generators. As a factory-sourced component, this set is manufactured to the exact dimensional tolerances required by Multiquip for a correct, by-the-book engine rebuild. The -0.50MM undersize specification makes it a precision-matched choice for crankshaft journals that have been machined or worn to that undersize dimension, ensuring proper oil film clearance and consistent engine operation across all covered generator models.
Key Features
- Exact Undersize Specification: — Engineered to the -0.50MM undersize dimension for crankshaft journals machined to that tolerance, delivering the correct oil clearance critical to engine longevity.
- Genuine OEM Component: — Sourced directly from Multiquip, this metal set meets the same material grade and dimensional standards as the original bearings installed at the factory.
- Direct Engine Rebuild Fit: — Designed to seat correctly during engine overhaul without secondary machining or shimming when the crankshaft has been ground to the matching undersize specification.
- Confirmed Generator Compatibility: — Verified fitment for DCA40SSAI, DCA60SSAI, and DCA40SSI ultra-silent generator models, keeping your engine rebuild on-spec for these units.
- Protects Crankshaft and Rod Journals: — Properly sized bearing metals maintain the oil film that separates rotating journals from the housing, preventing metal-to-metal contact that leads to rapid engine wear or seizure.
Bearing metal sets — commonly referred to as engine bearings or shell bearings — are the precision-machined inserts that support the crankshaft and connecting rod journals inside the engine block. They create a thin, pressurized oil film between rotating parts, which is what prevents direct metal contact during operation. An undersize set like this -0.50MM variant is used when a crankshaft has been reground to restore its journal surface, compensating for the reduced diameter so that correct operating clearance is maintained. When bearing metals are worn, out of tolerance, or incorrectly sized, oil pressure drops, heat builds rapidly, and catastrophic journal damage typically follows.
