The Multiquip 15390 Roller Chain #40S x 63P is a genuine OEM component designed for the FS3SP concrete saw. Sourced directly from Multiquip, this chain delivers the exact pitch, link count, and load rating required by the original equipment design. If you're servicing an FS3SP and need a chain replacement you can count on, part 15390 is the correct OEM specification part for the job.
Key Features
- OEM-Grade Chain Specification — #40S standard roller chain at 63 pitches, matched exactly to the drive system requirements of the FS3SP concrete saw.
- Direct Drive System Fit — Installs onto the FS3SP sprocket arrangement without modification, maintaining correct chain tension and engagement geometry.
- Confirmed FS3SP Compatibility — Verified fitment for the Multiquip FS3SP floor saw, so you're ordering with confidence against your specific machine.
- Consistent Power Transfer — A properly tensioned and dimensionally correct drive chain ensures smooth, uninterrupted power delivery to the blade, critical when cutting green or cured concrete.
- Wear Resistance Under Load — Chain stretch, link fatigue, or pitch creep on a worn chain causes blade speed variation and premature sprocket wear — replacing with a genuine OEM chain restores drive efficiency and protects surrounding drivetrain components.
The drive chain on a concrete saw transmits rotational power from the engine or gearbox to the blade shaft sprocket, keeping the cutting blade spinning at the correct operating speed. When a chain wears, stretches, or loses links, it can skip under load, creating uneven blade rotation that affects cut quality and places stress on the sprocket teeth. On a saw like the FS3SP, which is designed for flat-cut applications on fresh or cured concrete, a correctly sized and conditioned drive chain is essential to maintaining consistent blade performance and protecting the broader drivetrain from accelerated wear.
