Product Description
Ensure the smooth operation and longevity of your electric start system with the Genuine Royal Enfield Sprag Clutch Distance Washer. This OEM precision component (Part No: 570074/I) is a critical spacer used within the sprag clutch (one-way clutch) assembly on the Unit Construction Engine (UCE) platform.
The 570074/I distance washer is designed to maintain the exact axial clearance required for the sprag clutch to engage and disengage without binding. By providing a low-friction mating surface, it prevents the sprag gear from rubbing directly against the engine cases or the flywheel, reducing mechanical wear and heat buildup. Over time, these washers can become thin, grooved, or heat-damaged, leading to the dreaded “metallic clunk” during startup or a slipping sprag clutch. This genuine replacement is manufactured from hardened, high-grade steel to resist the intense rotational forces found behind the magneto cover.
Key Features:
-
Precision Thickness: Calibrated to factory specs to ensure the sprag clutch remains perfectly aligned for instant engagement.
-
Hardened Steel Build: Engineered to withstand the high-impact loads and friction generated every time you hit the starter button.
-
Wear Resistance: Features a smooth-ground finish to minimize drag and extend the life of the sprag gear and needle bearings.
-
OEM Thermal Stability: Designed to maintain its structural integrity despite the extreme temperatures inside the primary engine case.
-
Essential Overhaul Part: A mandatory replacement item during any sprag clutch repair to ensure the assembly functions like new.
