Multiquip 3233 Fender Washer 1.5 OD x 3/8 ID

The Multiquip 3233 is a genuine OEM Fender Washer 1.5 OD x 3/8 ID designed for a wide range of Multiquip and Whiteman equipment including HTX, STX, HHN, HTN, and J-Series power trowels, as well as QP4TKT trash pumps and WT/WTE water trailers. As a genuine OEM part, the 3233 is sourced directly from Multiquip to match the original hardware specifications used during manufacturing. This washer fits an extensive list of walk-behind and ride-on power trowels, making it a versatile hardware staple for service and repair across multiple machine families. Confirmed fitment includes models such as HTX6H, STX6H, HTX44Y5, HTX44K5, STX55Y6, HHN34TVD, HTN28K, and many others in the Whiteman and International trowel lineup.

Key Features

• Genuine OEM Hardware Grade — Manufactured to Multiquip's original dimensional specification, ensuring the correct bearing surface area and load distribution for the fastener assemblies it supports.
• Wide OD Bearing Surface — The 1.5-inch outer diameter spreads clamping load across a larger surface area, preventing pull-through on panels, covers, and structural mounting points.
• Direct-Fit Replacement — The 3/8-inch inner diameter matches the original bolt sizing used across Multiquip trowel, pump, and water trailer assemblies, dropping in without modification.
• Broad Cross-Family Fitment — Compatible with HTX, STX, HHN, HTN, JWN, J-Series, B-Series, HDA-Series trowels, QP4TKT trash pumps, and WT/WTE water trailers — one part number serves multiple machines in your fleet.
• Fastener Assembly Integrity — A correctly sized fender washer maintains proper clamp load and prevents fastener loosening under vibration, which is critical on high-cycle power trowel and pump applications.

A fender washer serves as a load-spreading interface between a bolt or nut and the surface being fastened. Its oversized outer diameter distributes the clamping force across a wider area, reducing the risk of the fastener pulling through sheet metal, housings, or panels — particularly on equipment that operates under constant vibration or mechanical stress. When a washer is missing, undersized, or deformed, fastener joints can loosen prematurely, leading to misaligned components, increased wear on adjoining hardware, or structural failure at the mounting point. Using the correct OEM specification washer ensures the fastener assembly performs as originally engineered for the life of the repair.
