The Genie 1288561GT is a genuine OEM Fuel Injector O-Ring, Deutz (89792GT) built for Genie S and SX telescopic boom lifts, Z articulating boom lifts, and GS scissor lifts equipped with Deutz engines. As a direct OEM replacement, this O-ring is produced to the same material and dimensional standards as the original, ensuring a correct seal at the fuel injector. Cross-reference part number 1288561GT and 89792GT against your machine's parts manual to confirm this is the correct O-ring for your unit before ordering.
Key Features
- Genuine OEM Fuel System Sealing Material — Manufactured to Genie's original compound and hardness specifications for the Deutz fuel injector application, maintaining the integrity of the fuel seal over the service life of the component.
- Direct Replacement for 89792GT — Part number 1288561GT cross-references to O-ring 89792GT; confirm both numbers in your parts manual to ensure an exact match for your engine configuration.
- Broad Genie Boom and Scissor Compatibility — Fits a wide range of Deutz-powered Genie S and SX telescopic booms, Z articulating booms, and GS scissor lifts, including models such as the S-60 XC, S-125, SX-180, SX-135 XC, Z-62/40, Z-45/25J IC, and GS-5390.
- Fuel-Tight Injector Seal — A sound O-ring maintains a leak-free connection at the injector body. A cracked or compressed O-ring allows fuel to weep past the injector seat, leading to rough running, fuel odor, and potential engine damage if left unaddressed.
- Fuel System Safety — A properly seated fuel injector O-ring prevents external fuel leaks at the injector, reducing fire risk and keeping the engine operating as designed on aerial lift equipment where fluid integrity is a safety consideration.
An O-ring at the fuel injector creates a pressure-tight seal between the injector body and the engine head, preventing fuel from escaping the injection circuit at that joint. On Deutz-powered Genie boom lifts and scissor lifts, this small component plays an outsized role — a deteriorated O-ring can allow fuel to leak externally or allow air into the injection circuit, both of which disrupt combustion and engine performance. Replacing a worn or damaged O-ring with the correct OEM part, such as 1288561GT, restores the seal to its original condition and keeps the fuel system functioning as designed.
