The Multiquip 37685 Flange Assembly 4.375" Outer Blade is a genuine OEM component designed for PS, SP, and CS series pavement saws. This includes compatibility with PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 models. Sourced directly from Multiquip, part 37685 is manufactured to the same specification as the original, ensuring a direct drop-in replacement with no guesswork. Whether you are returning a saw to service after blade wear or performing scheduled maintenance, this flange assembly keeps your cutting operation running at full capacity.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original specification, ensuring the correct clamping geometry and dimensional tolerance required to seat a 4.375" outer blade securely on the arbor.
- Direct Drop-In Replacement — Matches the original mounting pattern and flange diameter, allowing the assembly to bolt up to the spindle without machining or adaptation.
- Broad Pavement Saw Compatibility — Confirmed fitment across PS403016, PS403020, PS403026, PS403030, SP403016, SP403020, SP403026, SP403030, CS403016, CS403020, CS403026, and CS403030 pavement saws.
- Blade Retention Integrity — A properly functioning outer flange clamps the blade evenly against the inner flange, preventing lateral movement that causes uneven cuts, premature blade wear, or blade slippage under load.
- Cutting Safety Compliance — A worn or damaged outer flange compromises the blade clamping force needed to control the blade during operation; replacing it with a correct OEM flange restores the intended clamping load and operational safety margin.
The outer blade flange is a precision-machined clamping component that sandwiches the diamond or abrasive cutting blade against the inner flange on the saw's spindle arbor. By applying even radial clamping pressure across the blade's mounting bore, the flange assembly keeps the blade true and prevents any rotational or lateral play during the cut. When the flange is cracked, worn, or out of tolerance, clamping force becomes uneven, which can cause the blade to wobble, cut off-line, or — in severe cases — become unsafe during operation.
