Direct Power Transfer from the Engine! – Front Drive Sprocket (16 Teeth) for Jinling ATV 250 JLA-21B & 300 JLA-931E

Wear-Resistant Drive Component – Precision-case-hardened sprocket for the countershaft

Maximize your quad’s drivetrain efficiency! This Premium 16-Tooth Front Engine Sprocket is the critical component linking your transmission output shaft directly to the drive chain on Jinling 250 JLA-21B and 300 JLA-931E ATV models. Forged from high-strength, case-hardened steel alloy, it is engineered to easily handle the high-torque stresses straight from the motor. The precision-machined inner splines ensure a tight, play-free fit on the shaft, protecting it from stripping while offering smooth chain engagement and reduced friction.

Installation & Maintenance Instructions: (For guidance purposes only)

• Visual Check: Before installation, perform a visual check. Verify the tooth count (16), the internal shaft spline pattern, and the mounting holes for the retainer plate against your stock part.

• Drivetrain Kit Rule: It is highly recommended to replace the front sprocket, rear chain sprocket, and the chain simultaneously to prevent premature, uneven wear.

• Retainer Security: Inspect the sprocket locking plate. Always use a drop of medium-strength thread locker on the small locking retainer bolts to prevent them from backing out due to engine vibrations.
