CFMoto Drive Pulley Bolt (Reverse Thread / Left-Hand Thread)

Specification: M12 × 1.5 × 177mm | Reverse Thread (Left-Hand Thread)

Fits specific CFMoto 600cc ATV Series (191S-B Engine) and 1000cc SSV Series (2V91Y-D Engine)

📋 Product Overview & Key Features

This is a CFMoto Drive Pulley Bolt (Reverse Thread / Left-Hand Thread), specification M12 × 1.5 × 177mm. This bolt secures the CVT (Continuously Variable Transmission) drive pulley assembly to the engine crankshaft end. The reverse thread (left-hand thread) design effectively prevents the bolt from loosening due to vibration and inertial forces under specific engine rotation directions, making it a critical fastener in the drivetrain system.

Manufactured from high-strength alloy steel with precision rolled threads and heat treatment, offering superior tensile strength and fatigue resistance, ensuring a completely reliable connection between the drive pulley and the crankshaft.

🔩 Reverse Thread (Left-Hand Thread) Design: Specifically designed for particular engine rotation directions — tightens counter-clockwise, effectively prevents automatic loosening during operation.
⚡ High-Strength Alloy Steel: Premium alloy steel construction, Grade 12.9 strength, far exceeding standard bolt specifications, capable of withstanding high-frequency impact and extreme torque from the CVT system.
🛡️ Precision Rolled Threads: Formed using a rolling process for higher thread strength, precise engagement, and consistent clamping force.
🔧 OEM-Level Interchangeability: Manufactured to strict CFMoto OEM technical standards, ensuring identical dimensions, strength, and thread accuracy.

🔧 Genuine Quality Assurance: Material strength, thread precision, and dimensions are fully consistent with CFMoto original parts, ensuring reliable CVT system fastening performance.

🔧 Installation Guide (Reverse Thread Critical Notes)

⚠️ Reverse Thread (Left-Hand Thread) Important Notice:

This bolt has Reverse Thread (Left-Hand Thread) — opposite to standard thread direction! Please pay close attention to the following orientation:

🔧 Installation Direction (Tightening): To install, turn the bolt COUNTER-CLOCKWISE (Left rotation) to tighten. This is the correct tightening direction for reverse thread bolts.
🔩 Removal Direction (Loosening): To remove, turn the bolt CLOCKWISE (Right rotation) to loosen.
⚠️ Special Caution: Do NOT follow standard thread habits. Doing so may damage the bolt or prevent proper fastening!

📝 Detailed Installation Steps:

Thoroughly clean the bolt threads and crankshaft threaded hole, ensuring no oil, dirt, or old threadlocker remains.
Apply a high-quality thread locker (e.g., Loctite 243) to the middle section of the threads to prevent loosening due to vibration.
Use a precision torque wrench and tighten in 2-3 steps counter-clockwise to the specified torque.
Torque Specification: Strictly follow the torque value in the official service manual (consult your model's manual for the correct range).
After installation, perform a short test ride and re-check the torque.
