The Multiquip 37673 Bladeshaft 4000 Series is a genuine OEM component designed for Multiquip 4000 Series pavement and flat-cut saws, including PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 models. As a direct OEM replacement, part 37673 is manufactured to the exact tolerances required to keep your saw cutting accurately and safely. Sourced directly through authorized Multiquip supply channels, this bladeshaft is the correct choice when restoring your 4000 Series saw to full operational condition.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original engineering specifications, ensuring the shaft dimensions, taper, and keyway geometry match the original component exactly.
- Direct-Mount Replacement — Installs into the blade arbor assembly of 4000 Series saws using the original hardware and mounting points, requiring no modification to the saw housing or guard system.
- Broad 4000 Series Compatibility — Confirmed fitment across PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 pavement saw models.
- Blade Alignment and Cutting Accuracy — A true, undamaged bladeshaft keeps the diamond or abrasive blade running concentric and square, which directly affects cut straightness, depth consistency, and blade wear rate.
- Operational Safety — A worn or bent bladeshaft introduces blade wobble and vibration that can lead to blade damage or unexpected blade failure during cutting; replacing it promptly restores safe operating conditions.
The bladeshaft — also referred to as the blade arbor shaft — is the precision-machined spindle that mounts and drives the cutting blade on a pavement saw. It transfers rotational power from the drive system directly to the blade, holding it concentric and secure during operation. When a bladeshaft becomes bent, worn at the bearing journals, or damaged at the blade-mounting taper or keyway, the blade loses concentricity, producing visible wobble, increased vibration, uneven cuts, and accelerated blade wear. Left unaddressed, a compromised bladeshaft places excessive side-load stress on the blade, the bearings, and the saw frame, making prompt replacement essential to maintaining both cut quality and operator safety.
