Multiquip EM171 Dowel Pin 1/4" x 1"

The Multiquip EM171 is a genuine OEM Dowel Pin 1/4" x 1" used across a wide range of Multiquip and Whiteman equipment, including walk-behind and ride-on power trowels, concrete mixers, diaphragm pumps, rollers, and vibrators. As a genuine OEM component, EM171 is manufactured to the exact dimensional tolerances required for a proper fit in every application it supports. This single pin spans an extensive fitment list — including the J36-M30, HDA-SERIES, MQD3HA, MQD2HA, MC94SK, V305EK, and many more — making it a smart stocking part for shops and crews running multiple Multiquip machines. Sourced directly through authorized distribution, the EM171 ensures you receive the correct part every time.

Key Features

• Genuine OEM Dimensional Accuracy — Manufactured to exact 1/4" x 1" specifications, ensuring the pin seats flush and holds alignment without slop or play across all supported assemblies.
• Drop-In Installation — Designed to match the original bore geometry in each compatible housing or casing, so no filing, pressing modification, or shimming is required during installation.
• Broad Cross-Equipment Fitment — A single EM171 services walk-behind trowels, ride-on trowels, diaphragm pumps, rollers, mixers, vibrators, and more across the Multiquip and Whiteman product lines.
• Alignment Integrity — A correctly fitted dowel pin maintains precise component-to-component registration; a worn or missing pin allows critical assemblies to shift under load, accelerating wear on mating surfaces.
• Smart Inventory Choice — With fitment spanning models such as the HDA-SERIES, HTX6H, STX6H, MQD3H, MC64SK, and RX1575, stocking EM171 covers multiple machine families with one part.

A dowel pin is a small but essential fastening component used to locate and align two mating parts with precision. Unlike threaded fasteners, a dowel pin works by occupying a tight-tolerance hole shared between two components, preventing lateral movement or misalignment during operation. When a dowel pin shears, corrodes, or goes missing, the parts it was aligning can shift out of position, causing uneven wear, vibration, or outright mechanical failure in the assembly it supports — making prompt replacement with the correct OEM-spec pin critical to keeping the machine performing as intended.
