Multiquip C1154400004 Bearing Cover

The Multiquip C1154400004 Bearing Cover is a genuine OEM component designed for the DCA180SS, DCA220SS, and DCA250SS series ultra-silent and super-silent diesel generators. As a direct OEM replacement, this part is produced to the same specifications as the original, ensuring a correct fit within the alternator assembly. It is confirmed compatible across a wide range of DCA-series generator models including DCA180SSV, DCA180SSJU, DCA220SSJU, DCA220SSCU, DCA250SSI, and related Tier 4 variants. Sourcing the correct bearing cover by part number C1154400004 ensures you are installing the right component the first time.

Key Features

• Genuine OEM Construction — Manufactured to the original dimensional tolerances required to properly seat and protect the alternator bearing in DCA-series generator units.
• Direct Alternator Assembly Fit — Replaces the original cover at the bearing housing location without rework or modification to the alternator end frame.
• Broad DCA-Series Compatibility — Fits DCA180SS, DCA220SS, and DCA250SS model families including 50Hz, 60Hz, and Tier 4 variants such as DCA180SSJU4F, DCA220SSJU4F, and DCA220SSCU4I.
• Bearing Protection — A correctly fitted cover keeps contaminants away from the alternator bearing, maintaining smooth rotor operation and consistent power output over extended run times.
• Verified Part Number — Ordering by C1154400004 confirms you are specifying the exact Multiquip OEM cover for this generator family, not an approximate substitute.

The bearing cover encloses and protects the alternator's rotor bearing at the end of the generator housing. It acts as a shield against dust, debris, and moisture that could contaminate the bearing surface and accelerate wear. When this cover is cracked, missing, or improperly seated, the bearing is exposed to contaminants that cause premature failure — leading to increased rotor drag, heat buildup, and ultimately alternator damage. Replacing a damaged cover promptly with the correct OEM part keeps the bearing environment clean and the generator producing stable, reliable power output.
