Multiquip 21173-001 Magura Throttle Cables Housing

The Multiquip 21173-001 is a genuine OEM Magura Throttle Cables Housing designed for a wide range of Whiteman and Multiquip walk-behind power trowels, including the BH11C, BH90C, BS90C, JH55C, JH90C, B46S90, HDA-Series, JS36, JS60C, J36, M30H55, and many additional models in the J, JA, B, BA, C, and HDA series. As a factory-sourced component, this housing is manufactured to the same standards as the original part, ensuring a direct, trouble-free installation with no guesswork on fitment. This is the correct replacement for operators and service technicians maintaining throttle control integrity on their concrete finishing equipment.

Key Features

• Genuine OEM Construction — Sourced directly from Multiquip, this housing is manufactured to the same tolerances and material specifications as the original Magura throttle cable assembly it replaces.
• Direct-Fit Installation — Engineered to match the original mounting points and cable routing geometry on compatible walk-behind trowel models, allowing straightforward swapping with no fabrication or adaptation.
• Broad Model Coverage — Fits an extensive range of Whiteman and Multiquip walk-behind power trowels across the B, BH, BS, J, JA, JS, M30, HDA, and HPHA/HPLA series platforms.
• Throttle Control Integrity — A correctly seated throttle cable housing maintains smooth, consistent engine speed response at the operator handle — a worn or cracked housing can cause erratic throttle behavior, reducing finishing precision.
• Verified Part Number — Order with confidence: this part is the exact Multiquip OEM part number for this housing, eliminating compatibility risk when sourcing a replacement.

The Magura Throttle Cables Housing secures and guides the throttle cable assembly between the operator handle and the engine throttle linkage on walk-behind power trowels. It keeps the cable properly routed and protected, allowing the operator to make smooth, controlled adjustments to engine speed during concrete finishing operations. When the housing becomes cracked, worn, or damaged, cable movement can become inconsistent or restricted, leading to loss of throttle control and uneven blade speed — both of which directly affect the quality of the finished concrete surface.
