The Multiquip 1117510051 Oil Filler Cap is a genuine OEM component designed for the DCA40SSAI diesel powered generator. As a direct OEM replacement, it is manufactured to the exact specifications of the original part, ensuring a correct seal and proper fit at the oil fill port. This cap is confirmed for use on DCA40SSAI series equipment, making it a straightforward, no-guess replacement when servicing your generator's engine.
Key Features
- OEM Sealing Integrity — Manufactured to original material and thread specifications, delivering the same compression seal as the factory-installed cap to keep oil in and contaminants out.
- Direct Drop-In Replacement — Threads directly onto the oil fill port of the DCA40SSAI with no modification, matching the original cap's dimensions and thread pitch exactly.
- Confirmed DCA40SSAI Fitment — Verified for the Multiquip DCA40SSAI ultra-silent diesel generator series, so you can order with confidence.
- Protects Engine Oil from Contamination — A properly sealing oil filler cap prevents dust, debris, and moisture from entering the engine, protecting internal components during operation and storage.
- Fuel System Safety Relevance — A degraded or missing oil filler cap can allow oil vapors to escape and contaminants to enter, posing a risk to engine reliability and operator safety during extended run cycles.
The oil filler cap seals the engine's oil fill port, maintaining a closed crankcase system during operation. When the cap is cracked, cross-threaded, or missing its gasket, it allows oil mist to escape and creates an open path for dirt and moisture to contaminate the engine oil — accelerating wear on internal components. Replacing a damaged cap with a genuine OEM part like the Multiquip 1117510051 restores proper crankcase sealing and helps maintain clean, uncontaminated oil throughout the service interval.
