The Multiquip 37021 FNR Assembly is a genuine OEM component designed for PS, SP, and CS series pavement saws, including models PS403030, PS706020, PS706026, PS706030, PS706036, SP403016. As a direct OEM replacement, this assembly is produced to the same specifications as the original unit installed at the factory, ensuring a correct, trouble-free installation. DHS Equipment supplies this part direct, so you can confirm the part number and get the right component for your machine the first time.
Key Features
- Genuine OEM Construction — Manufactured to the same specification as the original assembly, maintaining precise engagement behavior and directional control response expected from the factory unit.
- Direct-Fit Replacement — Engineered to mount and connect exactly as the original FNR Assembly, with no reworking of adjacent components required during installation.
- Broad Pavement Saw Compatibility — Fits an extensive range of PS, SP, and CS series Multiquip pavement saws, including PS403016 through PS706036, SP403016 through SP706036, and CS403016 through CS706036.
- Restores Forward, Neutral, and Reverse Control — A worn or damaged FNR assembly compromises the operator's ability to shift drive direction cleanly; replacing it restores full, positive directional selection.
- Operator Safety Relevance — Proper FNR function is critical on self-propelled saws where unintended or sluggish directional response creates hazardous cutting conditions — a correctly functioning assembly keeps directional control sharp and predictable.
The FNR (Forward-Neutral-Reverse) Assembly is the drivetrain control mechanism that allows the operator to select the travel direction of a self-propelled pavement saw. It acts as the interface between the operator input and the drive system, enabling the machine to move into the cut, hold position, or back away cleanly. When this assembly wears or fails, the saw may slip out of gear, fail to engage a selected direction, or exhibit erratic propulsion behavior — all of which interrupt cutting progress and create safety concerns on an active cut line.
