The Multiquip 1117500120 Oil Filler Cap is a genuine OEM component designed for the DCA40SSAI, DCA45SSIU2, DCA40SSI, DCA45SSIU2-FEMA, and DCA45SSIU2-GEER ultra-silent diesel generators. As a direct OEM replacement, this cap is manufactured to the exact specifications of the original, ensuring a proper seal and secure fit on the engine oil fill port. Sourced directly through authorized Multiquip supply channels, this is the same part that ships on new equipment from the factory. If you are servicing any of the DCA-series ultra-silent generators listed above, the part is the correct replacement cap for the job.
Key Features
- OEM Sealing Integrity — Manufactured to exact thread pitch and sealing surface tolerances, ensuring the oil fill port is properly closed and protected from contamination and oil vapor loss.
- Direct Drop-In Replacement — Threads directly onto the engine oil fill port of compatible DCA-series generators with no modification to the cap, port, or surrounding components.
- Broad DCA-Series Compatibility — Confirmed fitment for DCA40SSAI, DCA45SSIU2, DCA40SSI, DCA45SSIU2-FEMA, and DCA45SSIU2-GEER ultra-silent generator models.
- Prevents Oil Loss and Contamination — A correctly sealed oil filler cap keeps engine oil clean and contained; a cracked, missing, or poorly fitting cap can allow dirt ingress and oil mist to escape during operation.
- Genuine Multiquip OEM Part — Supplied as original equipment, not a substitute, so you can be confident in material grade, thread engagement, and long-term durability under continuous generator operation.
The oil filler cap seals the engine's oil fill port after servicing, preventing oil from leaking out and blocking airborne contaminants such as dust and debris from entering the crankcase. On generator sets like the DCA-series ultra-silent units — which often run for extended periods in demanding environments — a properly sealing cap is essential to maintaining clean engine oil and stable oil levels. A damaged or missing cap can accelerate engine wear through oil contamination or cause oil consumption issues that go unnoticed until significant damage has occurred.
