Starter turns, but engine doesn't crank? This is it!

📋 Overview

If you hear the starter motor spinning but the engine is not cranking, this overrunning clutch assembly is the solution you need. This is a high-quality OEM replacement for CFMoto, including the overrunning clutch (Part # CF188-091200 / 0180-091200) and the driven gear (Part # CF188-091001 / 0180-091001).

The overrunning clutch (also known as a one-way or sprag clutch) is a critical starting system component that connects the starter motor to the engine's flywheel. During startup, it transmits the starter's torque to the engine. Once the engine starts, it immediately disengages to prevent the engine from over-speeding and damaging the starter. A slipping clutch is the direct cause of the classic "starter spins but engine doesn't turn over" failure.

✨ OEM Quality: Manufactured to strict OEM specifications with high-strength materials and precision rollers, ensuring reliable one-way locking and instant disengagement.

⚙️ Product Features

Direct Fix for a Classic Symptom: Specifically designed to solve the "starter spins, engine doesn't crank" issue caused by a slipping overrunning clutch.
Direct OEM Replacement: Perfectly matches CFMoto OEM part numbers for an accurate fit.
High-Strength Roller Design: Internal rollers made of high-quality bearing steel ensure reliable locking and instant disengagement.
Precision-Machined Gear: The 73-tooth driven gear has a precise module for smooth engagement with the starter motor pinion.
Complete Assembly: Includes both the overrunning clutch and the driven gear to resolve the starting drive issue in one step.

✅ Importance of Overrunning Clutch Replacement: The overrunning clutch is a high-failure component in the starting system. When you press the start button and hear the starter motor whirring but the engine's crankshaft doesn't move, it is almost certainly a slipping clutch. Repeated attempts to start can further damage the clutch or the starter gear. Replace the clutch assembly immediately upon experiencing this symptom.

⚠️ Installation Tip: This assembly is located inside the engine and requires removal of the magneto rotor and other components. Professional installation is recommended. While servicing, inspect the starter motor gear for wear and replace it if necessary.
