Multiquip 28451ZH8003 Starter Pulley

The Multiquip 28451ZH8003 Starter Pulley is a genuine OEM component designed for a wide range of Honda-engine-powered Multiquip equipment, including plate compactors such as the MVC-64H, MVC-70H, MVC-77, MVC-88GH, MVH-120GH, and MVH-R60H; concrete and mortar mixers including the MC-42S, MC-62S, MC-64S, EC-62S, WC-62S, and EM-70S; centrifugal and trash pumps such as the QP303H, QP-202TH, and T-20H; masonry saws including the MP1455H, MS18H5.5, and TRAK-14; and walk-behind trowels in the CA and HDA series. As a direct Multiquip OEM part, 28451ZH8003 is manufactured to the same specification as the original, ensuring a drop-in fit with no guesswork. Cross-equipment compatibility makes this pulley a smart stocking item for shops and fleets running multiple Multiquip Honda-powered units.

Key Features

• Genuine OEM Construction — Molded to the exact profile and engagement dimensions of the original Honda-engine recoil starter system, so rope wrap, tensioning, and spring engagement behave exactly as designed.
• Broad Honda-Engine Compatibility — A single part number covers plate compactors, concrete and mortar mixers, centrifugal and trash pumps, masonry saws, and walk-behind trowels across the Multiquip, Whiteman, Essick, and STOW product lines.
• Direct Drop-In Replacement — Installs into the existing recoil starter housing using the original hardware and rope routing, requiring only basic hand tools to complete the swap.
• Restores Reliable Starts — A cracked, worn, or rope-groove-damaged pulley causes hard starts, rope slippage, or complete starter failure; replacing with this part restores crisp, consistent engine engagement.
• Fleet-Friendly Stocking Part — One SKU serves dozens of models across multiple equipment categories, reducing the number of unique parts needed to keep mixed Multiquip fleets field-ready.

The starter pulley is the grooved disc at the center of the recoil starter assembly that winds and stores the pull rope under spring tension. When the operator pulls the starter handle, the rope unwinds from the pulley, spinning the engine crankshaft to initiate combustion; once released, the recoil spring retracts the rope back onto the pulley for the next pull. Over time, the rope groove can wear smooth, crack under UV exposure, or chip from impact, causing the rope to slip or jam. Replacing a damaged pulley promptly restores the full mechanical advantage of the recoil starter and prevents accelerated wear on the surrounding starter housing and recoil spring.
