The Multiquip 2258 Low Speed Kit is a genuine OEM replacement designed for HHN34TVD, HHN31V, BS46H11, BS46H90, and QP2TZ series equipment. As a direct OEM part, the 2258 is manufactured to the same specifications as the original component, ensuring a straight drop-in installation with no guesswork on compatibility. This kit covers a range of Multiquip ride-on trowels, walk-behind trowels, and trash pump applications, making it a versatile service item to have on hand. Confirm your model code against the fitment list before ordering to ensure the 2258 is the correct kit for your machine.
Key Features
- Genuine OEM Construction — Sourced directly from Multiquip, this kit matches the original low-speed components in material grade and dimensional tolerancing — no substitutions or compromises.
- Direct-Install Replacement — The 2258 is engineered to install exactly as the original kit did, using existing mounting points and hardware interfaces on supported models.
- Broad Multiquip Fitment — Compatible with HHN34TVD and HHN31V ride-on trowels, BS46H11 and BS46H90 walk-behind trowels, and QP2TZ trash pumps — verify your model code before ordering.
- Restores Low-Speed Operation — A worn or damaged low speed kit can cause erratic throttle response and rough idle behavior; replacing it with the correct OEM kit restores smooth, consistent low-speed function.
- Fuel System Integrity — For the QP2TZ trash pump application, proper low-speed calibration directly affects fuel metering at idle, helping maintain clean combustion and consistent pump output.
A low speed kit typically services the carburetor's idle and low-speed fuel delivery circuit, which controls how the engine runs at throttle positions below full load. This circuit governs smooth startup, stable idle, and response during light-load operation — all critical for equipment that cycles through variable demands like trowels transitioning blade speeds or pumps priming under load. When the low-speed components wear or become fouled, the engine may stumble, stall, or refuse to idle cleanly, signaling that the kit needs to be replaced as part of a routine carburetor service.
