Multiquip 90002883740 Breathing Bolt

The Multiquip 90002883740 Breathing Bolt is a genuine OEM component designed for Whiteman Mixer models including the WM70S/P series. Sourced directly from Multiquip, this part meets the exact specifications of the original hardware used in production. It installs as a direct replacement with no additional modification needed to the mixer assembly. Confirm your model code against the WM70S/P fitment reference before ordering to ensure accuracy.

Key Features

• Genuine OEM Hardware Spec — Manufactured to the exact thread pitch, head geometry, and material grade of the original bolt used on the production line.
• Correct Venting Function — Engineered to maintain proper airflow and pressure relief within the mixer drum assembly, keeping internal components operating within designed parameters.
• Direct-Fit for Whiteman Mixer Series — Confirmed fitment for WM70S/P Whiteman Mortar and Plaster Mixer models; drop-in replacement with standard installation.
• Drum Integrity Protection — A failed or missing breathing bolt can cause pressure buildup or contamination inside the drum housing, leading to accelerated wear on seals and internal components.
• OEM Part Number Confidence — Part number 90002883740 matches the Multiquip parts catalog directly, eliminating guesswork when sourcing a replacement.

The breathing bolt serves as a venting fastener within the mixer drum or gearbox housing, allowing air and pressure to equalize as the machine heats up during operation. Without proper venting, pressure differentials can force lubricants past seals or draw in contaminants, degrading internal components over time. Replacing a worn, damaged, or missing breathing bolt promptly protects the longevity of the surrounding assembly and keeps the mixer running cleanly.
