Product Description
Ensure a reliable and instantaneous start with the Genuine Royal Enfield Wheel Clutch. This OEM critical component (Part No: 571100/A) is the primary one-way gear assembly that allows the starter motor to crank the engine while preventing the engine’s rotation from “back-driving” the starter once it fired up.
The 571100/A Wheel Clutch is engineered specifically for the Unit Construction Engine (UCE) electric start system. It features high-precision internal sprags (locking elements) that engage immediately when the starter button is pressed and disengage smoothly as the RPMs rise. Over time, the internal springs or rollers can wear out, leading to the common “slipping” starter symptom or a harsh metallic “clunk” during engine shutdown. Replacing your worn unit with this genuine hardened-steel assembly ensures silent operation and protects your starter motor and flywheel from mechanical shock.
Key Features:
-
One-Way Engagement: Precision-calibrated sprag mechanism ensures 100% positive locking during startup and friction-free freewheeling thereafter.
-
High-Tensile Steel: Case-hardened to withstand the high torque loads required to turn over 350cc and 500cc high-compression cylinders.
-
Vibration Dampening: Engineered to handle engine kickbacks, preventing damage to the starter gear train.
-
OEM Tolerance: Manufactured to the exact dimensions of the UCE crankshaft interface for a perfect press-fit.
-
Durable Service Life: Built to last through thousands of heat cycles inside the oil-filled primary engine case.
