The Multiquip EM511890 Lever Pump Override V30-4 is a genuine OEM component designed for V304EH, V304ER, V304EY, V305EH, and V305EK walk-behind vibratory rollers. As a direct Multiquip OEM part, EM511890 is manufactured to the same standards as the original component installed at the factory, ensuring correct fit and proper function within the hydraulic pump control system. Verify your roller's model code against the fitment list to confirm compatibility before ordering.
Key Features
- Genuine OEM Construction — Manufactured by Multiquip to original design tolerances, ensuring the lever engages and releases the pump override mechanism with the correct travel and resistance.
- Direct-Fit Replacement — Engineered as a drop-in replacement for the V30-4 pump override assembly; mounts to existing hardware without modification to the roller's control linkage.
- Broad Roller Compatibility — Confirmed fitment across V304EH, V304ER, V304EY, V305EH, and V305EK walk-behind vibratory roller models.
- Restores Pump Override Control — A worn or damaged override lever can leave the pump locked in bypass or prevent proper disengagement, disrupting drive and compaction operation; replacing it restores full hydraulic control authority.
- Hydraulic System Integrity — Using the correct OEM lever ensures the override valve seats and releases cleanly, protecting downstream hydraulic components from pressure irregularities caused by a misfit or worn part.
The pump override lever is a manual control component that allows the operator to bypass or disengage the hydraulic drive pump — typically used when moving the roller without engine power or when servicing the drive system. When the lever is functioning correctly, the operator can engage and release the bypass position smoothly and positively. A cracked, bent, or worn lever can make it difficult to engage the override fully or cause it to slip out of position unexpectedly, which can affect machine controllability and the ability to safely move or service the roller.
