The Genie 77871-SGT is a genuine OEM Oil Cooler Option built for Genie S-80 and S-85 telescopic boom lifts. As a factory-sourced component, it is engineered to the exact specifications Genie requires for this option fitment, ensuring correct integration with the machine. DHS Equipment supplies part number 77871-SGT direct, so you can order with confidence that you are receiving the right part for your unit.
Key Features
- Genuine OEM Specification — Sourced directly from Genie, this oil cooler option meets the dimensional and material standards set at the factory for the S-80 and S-85.
- Direct-Fit Installation — Designed as an option component for these telescopic boom lifts, this part installs as intended without improvised adaptation.
- Confirmed Telescopic Boom Fitment — Compatible with Genie S-80 and S-85 telescopic boom lifts; cross-reference part number 77871-SGT against your machine's parts manual to confirm applicability to your serial number.
- Fluid Temperature Management — An oil cooler keeps fluid temperatures within the operating range required for consistent machine performance. A failed or missing cooler can allow fluid to overheat, accelerating wear on fluid-circuit components.
- Operational Reliability — Maintaining effective fluid cooling supports sustained duty cycles on demanding jobsites, helping the machine perform through extended lift and boom operations without thermal-related interruptions.
An oil cooler dissipates heat from fluid that circulates through the machine's circuit, keeping operating temperatures within the range the system is designed to handle. When fluid runs too hot, it loses viscosity and lubricating properties, which can cause accelerated wear or erratic component behavior. Fitting the correct OEM cooler option — part number 77871-SGT — ensures the cooling capacity matches what Genie specified for the S-80 and S-85, so the machine operates as intended across its full range of functions.
