The Genie 45177PGT Hydraulic Reservoir Top is a genuine OEM component designed for the Z-45/22D and Z-45/22DRT articulating boom lifts. Sourced directly from Genie, this part delivers the exact fit and seal integrity required to maintain a properly functioning hydraulic system on these machines. Cross-reference part number 45177PGT against your parts manual to confirm compatibility before ordering. For operators running either the standard or rough-terrain variant of the Z-45/22, this is the correct OEM-specified replacement.
Key Features
- Genuine OEM Seal Integrity — Manufactured to Genie's original material and dimensional specifications, ensuring the reservoir top seats correctly and maintains a contamination-free hydraulic system.
- Direct-Fit Replacement — Engineered to drop into the existing reservoir assembly on the Z-45/22D and Z-45/22DRT without rework or modification to surrounding components.
- Confirmed Fitment for Z-45/22 Variants — Compatible with both the Z-45/22D and Z-45/22DRT articulating boom lifts, covering the standard and rough-terrain configurations of this platform.
- Contamination Control — A properly seated reservoir top keeps airborne debris, moisture, and particulates out of the hydraulic fluid, protecting pumps, valves, and cylinders from premature wear.
- Operational Safety on Aerial Equipment — Hydraulic system integrity is critical on articulating booms; a failed or improperly sealed reservoir top can lead to fluid loss and unpredictable boom response, making correct replacement essential.
The hydraulic reservoir top serves as the protective cover and sealing interface for the machine's hydraulic fluid tank. It keeps the fluid supply clean and properly contained, preventing pressure loss and external contamination that can degrade hydraulic performance across the boom, platform, and drive functions. When this component is cracked, warped, or no longer sealing correctly, fluid contamination and air ingestion can accelerate wear throughout the entire hydraulic circuit — making timely replacement with the right part a straightforward way to protect the broader system.
