The Multiquip 28451ZH8003 is a genuine OEM Starter Pulley designed for a broad range of Multiquip and Whiteman equipment including CA4HM, MC64P, WM70S, MVC90H, QP205SH, and MP1455HP models. As a direct OEM replacement, this pulley is manufactured to the same specifications as the original component, ensuring a proper fit and consistent operation across the compatible equipment families. Sourced directly through authorized channels, part number 28451ZH8003 eliminates the guesswork of fitment when servicing your equipment. If your model is listed in the compatibility data, this is the correct starter pulley for the job.
Key Features
- Genuine OEM Construction — Manufactured to the same dimensional and material tolerances as the original pulley, ensuring the recoil starter rope seats and winds correctly every time.
- Drop-In Replacement — Mounts directly to the existing recoil starter housing with no additional hardware or modification to the starter assembly.
- Wide Equipment Compatibility — A single part number covering walk-behind trowels, plate compactors, mixers, pumps, saws, and generators including CA4HM, WM70S, MC64P, MVC90H, and QP205SH.
- Consistent Start Performance — A worn or cracked starter pulley causes the rope to slip, fray, or fail to retract, leaving equipment unable to start. Replacing it restores clean, repeatable pull-start engagement.
- Recoil System Integrity — Correct pulley geometry maintains proper rope tension and spring preload, protecting the broader recoil starter assembly from premature wear.
The starter pulley is the grooved spool inside the recoil starter housing around which the pull cord winds and unwinds. When you pull the starter rope, the pulley transfers that rotational force to the engine's crankshaft to initiate combustion. Over time, the pulley groove can wear, chip, or crack — causing the rope to slip out of the channel, retract unevenly, or fail to engage the engine altogether. Replacing a damaged starter pulley with a correctly sized OEM part restores the mechanical link between the operator and the engine, getting the machine started reliably on the first or second pull.
