The Genie 128987GT is a genuine OEM Water Pump designed for Genie S series telescopic boom lifts and Z series articulating boom lifts. Sourced directly from Genie, this part meets the exact specifications required by the machines it serves, ensuring a correct, direct replacement every time. Compatible across a broad range of models including the S-40, S-45, S-60, S-60 XC, S-60 HC, S-60 TRAX, S-60X, S-65, S-65 TRAX, S-80, S-80X, S-85, Z-45/25 IC, Z-45/25J IC, Z-60/34, Z-62/40, and Z-80/60. Cross-reference part number 128987GT against your machine's parts manual to confirm fitment before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original engineering tolerances, ensuring correct flow rate, pressure output, and seal compatibility for engine cooling systems on boom lifts.
- Direct-Fit Replacement — Matches the original mounting configuration and port dimensions, allowing straightforward installation without adaptation or modification to existing plumbing or brackets.
- Wide Boom Lift Coverage — Fits Genie S series telescopic booms from the S-40 through the S-85, plus Z series articulating booms including the Z-45/25 IC, Z-62/40, and Z-80/60.
- Sustained Cooling Performance — A properly functioning water pump maintains consistent coolant circulation through the engine, preventing overheating during extended duty cycles and heavy-use jobsite conditions.
- Operational Safety Assurance — Cooling system integrity is critical on aerial boom lifts operating at height; a failed pump can trigger thermal shutdowns or engine damage, taking the machine out of service unexpectedly.
The water pump is responsible for circulating coolant through the engine's cooling system, transferring heat away from the engine block and maintaining safe operating temperatures. On Genie boom lifts, where engines often run under sustained load during lifting and positioning cycles, a fully functional water pump is essential to keeping the powertrain within its designed temperature range. When the pump wears out or fails — typically through impeller degradation, bearing failure, or seal leakage — coolant flow drops, engine temperatures rise, and the machine may shut down or suffer internal damage if the condition goes unaddressed.
