Multiquip 05148600 Stop Spring 0.4MM

The Multiquip 05148600 Stop Spring 0.4MM is a genuine OEM component designed for QP3TZ and QP2TZ series trash pumps. Sourced directly through Multiquip's authorized parts supply, this spring is built to the exact wire diameter and tension specification required for correct governor or throttle stop function on these units. If you're servicing a QP3TZ or QP2TZ and need a verified, direct replacement, the 05148600 is the correct part.

Key Features

• Exact Wire Diameter: — Manufactured to the specified 0.4MM wire gauge, ensuring the correct spring rate and tension for consistent stop or governor response.
• Genuine OEM Sourcing: — Supplied as an authorized Multiquip OEM part, built to the same specification as the original component installed at the factory.
• Confirmed Trash Pump Fitment: — Verified for use on the QP3TZ and QP2TZ Multiquip trash pumps — cross-reference part number 05148600 before ordering.
• Throttle and Governor Integrity: — A correctly tensioned stop spring keeps engine speed control within its intended operating range; a fatigued or broken spring can cause erratic throttle behavior or loss of engine speed control.
• Drop-In Replacement: — Matches the original spring geometry so it seats and functions correctly without modification to the surrounding hardware.

A stop spring in a small engine application is a small but critical component that limits or returns the throttle or governor lever to a defined position. It provides the mechanical resistance that keeps the throttle linkage or governor arm from over-traveling, ensuring the engine operates within its designed RPM range. When this spring loses tension, stretches, or breaks, the engine may surge, fail to hold a steady speed, or become difficult to control under load — making timely replacement essential for safe and consistent pump operation.
