The Multiquip 9475021030 Oil Switch Assembly C30HDG is a genuine OEM component designed for the C30HDG concrete pump. As a direct OEM replacement sourced through Multiquip's authorized parts program, this assembly is built to the same specification as the original unit installed at the factory. If you're servicing a C30HDG and need a like-for-like swap, this is the correct part to restore proper oil pressure monitoring to your machine.
Key Features
- Genuine OEM Specification — Manufactured to the exact electrical and pressure-sensing parameters required by the C30HDG oil monitoring circuit, ensuring accurate switch activation at the correct threshold.
- Direct Assembly Replacement — Supplied as a complete switch assembly, dropping into the existing mount point without the need to source individual sub-components.
- Confirmed C30HDG Fitment — Verified for the Multiquip C30HDG cycloidal-drive concrete pump; always cross-reference your serial plate before ordering.
- Protects Engine and Drive Components — A correctly functioning oil switch triggers shutdown or warning when oil pressure drops, preventing catastrophic internal damage during operation.
- Electrical Integrity — OEM-grade connector and sensing element maintain the correct circuit resistance and switching behavior expected by the C30HDG control system.
The oil switch assembly monitors engine or pump oil pressure and sends a signal to the machine's control system when pressure falls outside the safe operating range. When functioning correctly, it acts as a first line of defense against low-oil conditions that could seize internal components or cause irreversible damage to the drive system. A failed or faulty oil switch may allow the machine to continue running under dangerous conditions — or conversely, cause nuisance shutdowns that interrupt work — making timely replacement essential for both protection and productivity.
