Key Features
- Genuine OEM Engine Compatibility — Engineered specifically for the Cummins B3.9 engine, matching the exact tube geometry, connection points, and material grade required for correct starting-aid delivery.
- Direct OEM Replacement — Mounts into the existing starting-aid circuit without modification, using the original attachment points on Cummins B3.9-powered machines.
- Confirmed Fitment for Large Telescopic Booms — Compatible with Genie S-100, S-105, S-120, and S-125 telescopic boom lifts equipped with the Cummins B3.9 engine.
- Cold-Start Reliability — A functioning starting aid tube delivers ether or starting fluid directly into the intake, enabling the engine to fire in low-temperature conditions where a failed or cracked tube would leave the machine unable to start.
- Operational Safety on Large-Platform Booms — On high-reach telescopic booms, reliable engine starting is critical to controlled operation and safe lowering of the platform. A compromised starting-aid system can create unpredictable engine behavior in cold conditions.
The starting aid tube routes starting fluid from the aid canister into the engine's air intake to assist combustion during cold-weather starts. On diesel engines like the Cummins B3.9, this tube must deliver a precise, directed flow — a cracked, blocked, or incorrectly routed tube reduces starting-fluid delivery and can result in hard starts or a no-start condition in cold temperatures. Replacing a worn or damaged tube with this genuine OEM part restores the engine's cold-start system to its original operating condition, keeping your large-platform boom lift productive through seasonal temperature swings.
