The Genie 77986GT is a genuine OEM 2.0MM Orifice designed for the Z-34/22 IC and Z-34 IC articulating boom lifts. This component equalizes pressure on both sides of the flow divider/combiner valve, ensuring balanced fluid distribution across the circuit it serves. As a genuine Genie OEM part, it is manufactured to the exact dimensional and material specifications required for correct installation. Cross-reference part number 77986GT against your machine's parts manual to confirm this is the correct item for your unit.
Key Features
- Genuine OEM Dimensional Accuracy — Precision-machined to the exact 2.0MM orifice diameter specified for this application, ensuring correct flow characteristics in the circuit it serves.
- Direct OEM Replacement — Manufactured to Genie's original specifications for a direct drop-in fit with no secondary modification needed.
- Pressure Equalization Function — Designed specifically to equalize pressure on both sides of the flow divider/combiner valve, keeping fluid distribution balanced across the system.
- Correct Fitment for Z-34 IC Models — Built for the Z-34/22 IC and Z-34 IC articulating boom lifts; cross-reference part number 77986GT against your parts manual before ordering.
- Operational Reliability — A correctly sized orifice maintains the intended pressure balance in the circuit; an incorrect or worn orifice can disrupt flow distribution and affect machine performance.
An orifice is a precisely sized restriction within a fluid circuit, used to meter flow and control pressure differentials between connected passages. In this application, the orifice equalizes pressure on both sides of the flow divider/combiner valve, ensuring that fluid is distributed evenly to the circuits the valve serves. When an orifice is blocked, damaged, or replaced with an incorrect size, pressure balance is lost, which can result in uneven or erratic machine movement. Using the correct OEM orifice — sized to the original 2.0MM specification — restores proper function to the circuit.
