The Multiquip 1685107090 is a genuine OEM Main Bearing Case Assembly designed for the Z482-E3B engine found in DAC7000SS, DAC7000SSW, DAC7000SSA ultra-silent diesel generators and DLW300ES series diesel light welders. As a direct OEM replacement sourced through Multiquip's authorized parts network, this assembly is held to the same manufacturing standards as the original component that left the factory. Confirm your model code and engine designation before ordering to ensure a correct, trouble-free installation.
Key Features
- Precision-Matched Bearing Housing — Manufactured to the exact bore tolerances of the Kubota Z482-E3B engine block, ensuring proper crankshaft alignment and bearing retention.
- Genuine OEM Component — Supplied directly through Multiquip's authorized parts chain, identical in material and specification to the original assembly installed at the factory.
- Confirmed Fitment — Verified for DAC7000SS, DAC7000SSW, and DAC7000SSA ultra-silent generator models, as well as DLW300ES series diesel light welders powered by the Z482-E3B engine.
- Protects Crankshaft and Engine Longevity — A correctly seated main bearing case maintains oil film integrity around the crankshaft journals; a worn or damaged housing accelerates bearing failure and risks catastrophic engine damage.
- Drop-In Replacement — Matches the original bolt pattern and housing geometry of the Z482-E3B engine, allowing straightforward installation without machining or modification.
The main bearing case is a structural engine component that houses and retains the crankshaft's main bearings, holding them in precise alignment with the engine block. It works in conjunction with the crankshaft and bearing inserts to maintain the tight tolerances needed for proper oil pressure and smooth power transfer. When the bearing case becomes worn, cracked, or warped, it can cause bearing knock, loss of oil pressure, and ultimately engine seizure — making timely replacement critical to keeping the engine operational.
