The Multiquip 1525 Oil Fill Cap Assembly is a genuine OEM component designed for C30HDNI and C30HDN series Mayco concrete pumps, including the C30HDNI Precision and C30HDNI Zenith variants. As a direct OEM replacement, this cap assembly is produced to the same specifications as the original part, ensuring a correct, trouble-free installation. Sourced directly through authorized Multiquip distribution, the 1525 is the right call when maintaining your concrete pump's fluid system integrity. Verify your model code against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to original Multiquip tolerances, this oil fill cap assembly delivers the correct thread engagement and seal compression needed to keep the pump's lubrication system fully closed and contamination-free.
- Direct Drop-In Installation — Engineered to match the original mounting interface on C30HDNI and C30HDN pumps, this assembly installs exactly as the factory unit did — no reworking of the fill port required.
- Confirmed Fitment for C30HDN Family — Compatible with C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith concrete pump models in the Mayco lineup.
- Protects Lubrication System Performance — A properly seated oil fill cap keeps the pump's oil reservoir sealed against dust, debris, and moisture — all of which accelerate internal wear when allowed to enter the system.
- Fuel System Safety Compliance — A failed or improperly fitted oil fill cap on a working concrete pump can lead to oil loss or contamination under operating conditions; replacing with the correct OEM assembly maintains safe fluid containment.
The oil fill cap assembly seals the oil fill port on the concrete pump's engine or gearbox lubrication system, preventing contaminants from entering the oil reservoir during operation and transport. A damaged, worn, or missing cap allows dirt, water, and debris to mix with the lubricating oil, leading to accelerated internal wear and potential pump failure. Replacing a faulty cap assembly promptly with the correct OEM part is one of the simplest and most effective ways to protect the long-term mechanical health of your concrete pump.
