The Wacker Neuson Spring is a genuine OEM component designed for the PT6LT, PT6LT T4, and PT6LT(I) series trash pumps. As a direct factory replacement, it matches the original specification so the pump operates exactly as intended. This Spring fits the PT6LT Pump with Trailer, PT6LT Pump with Trailer T4, and PT6LT(I) Trash Pump configurations, making it easy to confirm compatibility before you order.
Key Features
- Genuine OEM Construction: — Manufactured to the same material grade and tension spec as the original, ensuring consistent spring force and long service life in a high-cycle pump environment.
- Drop-In Replacement: — Matches the original mounting points and dimensions so the Spring seats correctly without rework or adjustment during installation.
- Broad PT6LT Fitment: — Verified for the PT6LT Pump with Trailer, PT6LT Pump with Trailer T4, and PT6LT(I) Trash Pump — covering the full 6-inch trash pump lineup.
- Maintains Pump Priming and Flow Consistency: — A correctly tensioned spring keeps internal components in their proper operating position, preserving the pump's self-priming capability and steady discharge performance.
- Part Number Confidence: — Order by Wacker Neuson part number 5000077635 to ensure you receive the correct spring for your specific PT6LT model variant.
A spring within a self-priming trash pump typically functions as a return or seating component — holding a valve, flap, or mechanical element in the correct position during priming and pumping cycles. When the spring loses tension, deforms, or breaks, the affected component can fail to seat or return properly, leading to loss of prime, reduced flow, or irregular pump behavior. Replacing a worn spring promptly restores the mechanical action the pump relies on to move water and entrained solids efficiently on the job.
