The Multiquip 1525585030 Oil Fill Cap Assembly is a genuine OEM component designed for C30HDNI and C30HDN series Mayco concrete pumps, including C30HDNI Precision and C30HDNI Zenith variants. As a direct OEM replacement, it is manufactured to the same specification as the original part, ensuring a proper seal and correct fitment on the oil fill port without any modification. Sourced directly through authorized Multiquip supply channels, the 1525585030 is the correct part for operators who need a dependable, like-for-like replacement. Confirm your model against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Sealing Integrity — manufactured to original specification, ensuring the oil fill port is properly sealed against contamination and leakage on every service cycle.
- Direct Drop-In Replacement — threads and cap dimensions match the original assembly exactly, so installation on C30HDNI and C30HDN pump housings is straightforward.
- Broad C30 Series Fitment — compatible with C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith concrete pump models.
- Protects Engine Oil from Contamination — a failed or missing oil fill cap allows debris, moisture, and dirt into the oil system, accelerating wear on internal pump components; this assembly restores full protection.
- Fluid System Safety — a correctly seated oil fill cap prevents pressurized oil from escaping during operation, reducing the risk of slips and unplanned fluid loss on the worksite.
The oil fill cap assembly seals the oil fill port on the concrete pump, providing a secure, removable closure that keeps the lubrication system clean and contained. A damaged or degraded cap can allow contaminants into the oil, accelerating internal wear and leading to premature pump failure. Replacing a worn cap assembly promptly with the correct OEM part maintains oil system integrity and supports consistent pump performance on the job.
