The Multiquip 505205 Small Pulley is a genuine OEM component designed for WM63SLF, WM63H8, WM63H5, and WM63E series Whiteman equipment. As a direct OEM replacement, this pulley is manufactured to the same specifications as the original part, ensuring correct belt engagement and drive system alignment across compatible models. If you are servicing a Whiteman mixer or walk-behind power trowel in the WM63 family, the 505205 is the correct replacement pulley to restore proper drivetrain operation.
Key Features
- Genuine OEM Construction — Manufactured to the original dimensional and material specifications, ensuring correct belt seating and groove profile for this drive system.
- Direct OEM Drop-In Replacement — Engineered to match the original mounting configuration on WM63 series equipment, allowing straightforward installation without modification.
- Broad WM63 Family Fitment — Compatible with WM63SLF, WM63H8, WM63H5, and WM63E models, covering both Whiteman mixer and walk-behind trowel applications in this series.
- Drive System Integrity — A correctly sized and properly seated small pulley maintains the right belt tension ratio, preventing slippage, premature belt wear, and loss of power transfer to the working components.
The small pulley is a core element of the belt-drive system on Whiteman mixers and walk-behind trowels. It works in tandem with the larger drive pulley to transfer rotational power from the engine to the machine's working components via a drive belt, with the size differential between the two pulleys determining the output speed and torque. When the small pulley is worn, cracked, or damaged, belt tracking suffers — leading to slippage, uneven wear on the belt, and ultimately a loss of drive performance. Replacing a worn pulley promptly restores efficient power transmission and protects the belt from accelerated deterioration.
