The Multiquip 15389 Roller Chain 40S x 57P is a genuine OEM component designed for the FS3SP self-propelled concrete saw. As a direct Multiquip OEM part, it is manufactured to the exact chain pitch, length, and link specification required by the FS3SP drivetrain. Sourced through DHS Equipment, this is the correct replacement when your saw's drive chain shows signs of stretch, wear, or damage. Confirm your model code against FS3SP before ordering to ensure a direct fit.
Key Features
- OEM Chain Specification — #40S pitch and 57-pitch link count match the exact drivetrain geometry of the FS3SP, ensuring correct engagement with the drive sprockets without adjustment.
- Genuine Multiquip OEM Part — Produced to the same standards as the original chain installed at the factory, maintaining consistent power transfer and wear characteristics across the drive system.
- Direct Replacement for FS3SP — Confirmed fitment for the Multiquip FS3SP self-propelled concrete saw; drops in as a like-for-like swap with the existing drive assembly.
- Maintains Drive System Integrity — A worn or stretched roller chain causes blade speed variation, erratic self-propelled travel, and accelerated sprocket wear — replacing with the correct OEM chain restores smooth, consistent operation.
- Part Number 15389 — Use this number to cross-reference against your FS3SP parts manual or service diagram before purchase to confirm you have the right chain for your machine's configuration.
A roller chain transfers rotational power from the engine-driven sprocket to the blade or propulsion system by linking two or more sprockets through a series of interlocked roller links. The chain must match the pitch of the sprockets it runs on — in this case, #40S — and the correct link count (57 pitches) ensures the chain closes properly at the correct tension without modification. When a roller chain stretches beyond its wear limit, it skips teeth, transmits power unevenly, and places excess stress on the surrounding sprockets and bearings, leading to broader drivetrain damage if not addressed promptly.
