The Multiquip 31225ZJ1004 Pinion Stopper Set is a genuine OEM component designed for Stow Pavement Saws and Street Pro Flat Saws, including CS8 and SP2 series models. As a direct OEM replacement, this set meets the original engineering specifications Multiquip built into these machines, ensuring the pinion assembly is properly retained under cutting load. Confirmed fitment spans a wide range of models including CS813H20, CS820H20, CS8CE13H20, CS8CE20H20, CC813H20, CC8CE13H20, SP2, SP2S13H20, SP2S20H20, SP213H20, SP213H20A, SP2CE13H20, SP2SCE13H20, SP2SCE20H20, SP2S20H20A, and N35244. Sourced directly from Multiquip, this part ships with full OEM confidence for operators who need an exact-match replacement.
Key Features
- Genuine OEM Retention Integrity — Manufactured to Multiquip's original design spec, ensuring the pinion is held in position with the correct pre-load and engagement geometry specific to these saw drivetrains.
- Drop-In Fitment for CS8 and SP2 Series — Engineered to install directly into the saw's gearbox or drive housing without rework, restoring the assembly to its original configuration.
- Broad Model Coverage — Fits Stow Pavement Saw models CS813H20, CS820H20, CS8CE13H20, CS8CE20H20, CC813H20, and CC8CE13H20, plus Street Pro Flat Saw models SP2, SP213H20, SP213H20A, SP2S13H20, SP2S20H20, SP2S20H20A, SP2CE13H20, SP2SCE13H20, SP2SCE20H20, and N35244.
- Drivetrain Stability Under Load — A correctly seated pinion stopper set keeps blade drive engagement consistent during cutting passes; a worn or missing set can allow axial pinion movement, leading to uneven blade engagement and accelerated gear wear.
- Cutting Safety Assurance — Proper pinion retention is critical in pavement and flat saw applications where blade torque loads are high; using the correct OEM set maintains the mechanical limits the drivetrain was designed to operate within.
The pinion stopper set functions as a mechanical retention assembly within the saw's drive system, limiting axial movement of the pinion gear and keeping it correctly positioned relative to its mating components. In pavement and flat saw applications, the drivetrain experiences significant torque and vibration during blade operation, and the stopper set absorbs and constrains the forces that would otherwise cause the pinion to walk out of position. When this set wears out or fails, the pinion can shift under load, causing irregular blade drive, increased noise, and progressive damage to the surrounding gear components.
