Product Description
Ensure a smooth and quiet startup every time with the Genuine Royal Enfield Double Gear Assembly. This OEM transmission component (Part No: 570570/E) is the critical intermediate gear set that sits between the starter motor pinion and the sprag clutch on the Unit Construction Engine (UCE) platform.
The Double Gear Assembly features a unique two-stage design (hence “Double Gear”) that acts as a torque multiplier, allowing the small starter motor to turn over the heavy high-compression 350cc or 500cc engine. Precision-cut from high-carbon hardened steel, this gear is engineered to handle the sudden mechanical shock of engine “kickback” without chipping or shearing teeth. If you hear a “grinding” or “slipping” sound when pressing the starter button, it is often due to worn teeth on this assembly. Replacing it with this genuine part ensures perfect gear mesh and prevents damage to the more expensive starter motor or flywheel.
Key Features:
-
High-Carbon Steel Build: Heat-treated for maximum surface hardness to resist wear during thousands of start cycles.
-
Precision Tooth Profile: OEM machining ensures silent operation and smooth engagement with the starter pinion and sprag gear.
-
Integrated Bushing: Features a factory-fitted inner sleeve for low-friction rotation on the starter gear pin.
-
Shock Resistance: Designed to absorb the stresses of high-compression start-ups and potential engine backfire.
-
Direct Replacement: A plug-and-play component for the magneto-side engine casing.
