The Genie 43684GT Piggyback Pump is a genuine OEM component built for the Z-34/22 IC and Z-34 IC articulating boom lifts. As a direct OEM replacement, this pump is sourced to Genie's own specifications — the same Barnes M42, 4CC unit fitted at the factory — so there are no compatibility concerns when swapping it in. Cross-reference part number 43684GT against your machine's parts manual to confirm it is the correct item for your serial number before ordering.
Key Features
- Genuine OEM Construction — Supplied as an authentic Genie part, built to the same Barnes M42, 4CC specification as the original unit, ensuring dimensional and performance conformity.
- Direct Drop-In Replacement — Engineered to mount and connect exactly as the factory-installed pump, eliminating guesswork during installation.
- Confirmed Fitment — Designed for the Z-34/22 IC and Z-34 IC articulating boom lifts; verify against your parts manual using part number 43684GT before ordering.
- Restored Output Capacity — A fresh pump at the correct 4CC displacement restores proper fluid flow to the circuit it serves, maintaining normal machine operation after wear or failure.
- Operational Safety — On an aerial lift, a failing pump can compromise boom movement and control response; replacing it with the correct OEM unit keeps the machine performing as designed.
A piggyback pump is a secondary pump mounted in tandem with a primary pump, drawing drive from the same shaft to supply a separate circuit on the machine. When this pump wears out or loses displacement, the circuit it serves becomes sluggish or unresponsive, which can affect boom functions on the lift. Replacing it with the correct OEM unit — the Barnes M42 at 4CC displacement — restores proper flow and pressure to that circuit, bringing the machine back to its intended operating condition.
