The Genie 77387GT is a genuine OEM M46/Gear Pump, 2.8/.67 built for Z-45/25 and Z-45/25J IC Power articulating boom lifts. As a direct Genie OEM part, it is manufactured to the same specifications as the original unit installed at the factory, ensuring proper fit and function within the machine. Cross-reference part number 77387GT against your machine's parts manual to confirm this is the correct pump for your specific unit before ordering.
Key Features
- Genuine OEM Gear Pump — Built to Genie OEM specifications with the correct displacement ratings (2.8/.67) to match the original pump's output characteristics and dimensional envelope.
- Direct-Replacement Fit — Engineered to install in place of the original unit with the correct porting, mounting configuration, and gear specifications for a straightforward swap.
- Confirmed Fitment — Compatible with Z-45/25 and Z-45/25J IC Power articulating boom lifts; always verify against your serial number and parts manual before ordering.
- Restored Hydraulic Output — A worn or failed gear pump causes sluggish boom movement, erratic lift response, or complete loss of hydraulic function. Replacing it with this genuine OEM part restores the fluid flow the machine depends on for full articulating boom operation.
- Operational Safety — On an articulating boom lift, reliable hydraulic pump function is directly tied to safe platform movement and positioning. Using the correct OEM replacement supports the system integrity the machine was designed around.
A gear pump is a positive-displacement pump that moves hydraulic fluid through the machine by meshing rotating gears, which draw fluid in on one side and push it out under pressure on the other. On articulating boom lifts like the Z-45/25 and Z-45/25J IC Power, this pump is responsible for generating the hydraulic pressure that drives boom articulation, lift, and other powered functions. When the pump wears out or fails, fluid pressure drops, causing slow or unresponsive boom movement — and the machine must be taken out of service until the pump is replaced.
