The Multiquip 492055 is a genuine OEM Pulley (Small) Honda 5.5 HP designed for Whiteman mortar mixer models WM70S/P, WM63H8, WM63H5, and WM63E, Essick mixer models EM70P/S, and RAMMAX roller models RW1504HF (up to S/N ) and RW1404MR (S/N 326075 and up). As a direct Multiquip OEM component, part 492055 is manufactured to the same specification as the original, ensuring correct belt engagement and drive performance. Verify your model number and serial number range before ordering to confirm fitment, particularly for the RW-series rollers where serial number breakpoints apply. DHS Equipment supplies this part direct, so you can order with confidence knowing you are receiving the correct component for your machine.
Key Features
- Genuine OEM Drive Geometry — Machined to the exact diameter and groove profile of the original Honda 5.5 HP drive pulley, maintaining proper belt tension and speed ratio.
- Drop-In Installation — Matches the original shaft bore and keyway dimensions on compatible Whiteman and Essick mixer engines, allowing straightforward swap-out without modification.
- Broad Whiteman and Essick Mixer Fitment — Confirmed for WM70S/P, WM63H8, WM63H5, WM63E, and EM70P/S mixer models, covering a wide range of Honda 5.5 HP-equipped units.
- Serial-Number-Verified Roller Compatibility — Fits RW1504HF rollers up to S/N 1534188 and RW1404MR rollers from S/N 326075 and up — always cross-reference your serial number before ordering.
- Sustained Drive Belt Performance — A correctly sized small pulley maintains the belt path alignment that keeps mixer drum speed consistent; a worn or undersized pulley causes belt slippage, premature belt wear, and reduced mixing output.
The small drive pulley sits on the engine output shaft and works in tandem with the larger driven pulley to transfer engine power through a belt to the mixer drum or roller drive system. The diameter ratio between the two pulleys determines the output speed, so using the correct OEM-specification pulley is essential for the machine to operate at its intended drum or roller speed. When this pulley wears, develops groove damage, or is replaced with an incorrect size, belt slip and accelerated belt wear follow, ultimately reducing the machine's ability to mix material evenly or drive the roller drum at proper speed.
