The Multiquip 492077 Large Pulley is a genuine OEM component designed for Whiteman plaster and mortar mixer models WM63E, WM63H5, WM63H8, and WM63SLF. Sourced directly from Multiquip, this pulley is an exact match for the original part, ensuring proper belt engagement and drive system performance. If you are servicing any of the WM63 series mixers, the 492077 is the correct OEM replacement to restore the drivetrain to its original operating condition.

Key Features

  • Genuine OEM Drive Geometry — Manufactured to the same dimensional specifications as the original, ensuring correct belt wrap angle and load-bearing capacity for the WM63 mixer drive system.
  • Direct Bolt-On Replacement — Matches the original mounting bore, keyway, and hub profile of the WM63 series, allowing straightforward installation without machining or modification.
  • Broad WM63 Series Fitment — Confirmed compatibility with WM63E, WM63H5, WM63H8, and WM63SLF Whiteman mixer models.
  • Consistent Power Transfer — A correctly sized large pulley maintains the designed drive ratio, keeping drum rotation speed and torque output within the mixer's intended operating range.
  • Verified OEM Part Number — Part number 492077 matches Multiquip's official parts documentation, so you can order with confidence that this is the right component for your machine.

The large pulley is a core element of the belt-driven power transmission system on Whiteman WM63 series mortar and plaster mixers. It works in conjunction with the drive belt and smaller drive pulley to transfer power from the engine to the mixing drum, stepping down speed and multiplying torque in the process. When the large pulley becomes worn, cracked, or damaged, belt slippage and inconsistent drum rotation follow — reducing mixing efficiency and placing additional stress on surrounding drivetrain components.
