The Multiquip 28979-501 Trunnion Support is a genuine OEM component designed for the MS18H5.5, MS18H8, and MS18E masonry saws. Sourced directly from Multiquip, this part meets the exact engineering specifications your saw was built with, ensuring a proper fit without guesswork. It is a direct replacement for the original trunnion support on all three compatible MS18 series models. DHS Equipment stocks this part to help you get your saw back in service quickly.

Key Features

  • Genuine OEM Construction: — Manufactured to Multiquip's original design tolerances, ensuring the structural integrity and load-bearing performance expected of a trunnion support.
  • Direct Drop-In Replacement: — Matches the original mounting geometry and hardware interfaces on MS18 series masonry saws for a clean, straightforward installation.
  • Confirmed MS18 Series Fitment: — Verified compatible with the MS18H5.5, MS18H8, and MS18E masonry saw models.
  • Blade Angle Stability: — A properly functioning trunnion support keeps the blade assembly seated and aligned through cutting cycles, preserving cut accuracy and reducing wear on surrounding components.
  • Structural Safety Relevance: — As a load-bearing pivot component, replacing a worn or cracked trunnion support is critical to maintaining safe blade control and preventing unexpected movement during operation.

The trunnion support is a structural pivot bracket that anchors and aligns the blade assembly on a masonry saw, allowing the blade head to tilt or rotate to the correct cutting angle. It carries significant mechanical load during cutting and serves as the foundation for accurate, repeatable cuts in brick, block, and stone. When the trunnion support is cracked, worn, or loose, blade alignment becomes inconsistent, cutting accuracy deteriorates, and stress is transferred to adjacent components — making timely replacement essential for both performance and operator safety.
