DAYUAN Motorcycle Flywheel Puller Kit — 10-Piece Metric Set with Hardened Steel, Black Oxide Case

DAYUAN's 10-piece motorcycle flywheel puller kit gives you the right threaded puller for most small-engine flywheels, letting you remove rotors cleanly without damaging threads or covers.

This compact kit includes five single-ended and five double-ended pullers in a range of metric thread sizes to fit motorcycles, scooters, ATVs, and dirt bikes. Each tool is forged from steel with a black oxide finish for corrosion resistance and comes in a blow-molded case for organized storage. The selection covers 15 common applications, including rare sizes and left/right thread options so you can tackle most common small-engine stator and flywheel removal jobs without improvising or risking damage.

Which engines and vehicles will these pullers fit?

The kit covers a wide variety of small engines used on bikes, scooters, ATVs, and dirt bikes by offering common metric thread sizes and several dual-ended varieties. Check the flywheel nut thread and pitch against the included sizes before use. Note: except for M27x1.0 (left-hand), all pieces are right-hand thread.

• Fits many Japanese, European, and Chinese small engines found on motorcycles and scooters
• Suitable for many ATVs and off-road/dirt bikes with metric flywheel threads
• Includes both single-ended and double-ended pullers to match stud or nut thread pitches
• Useful for stator/flywheel removal during electrical or ignition servicing

How do I choose the correct puller size and thread direction?

Identify the flywheel thread by measuring the internal thread diameter and pitch or by checking the service manual. Match those values to a puller in the kit; the double-ended pieces cover two pitches per tool to increase compatibility. Remember that only the M27x1.0 puller is left-hand thread—everything else is right-hand.

• Measure thread diameter (e.g., M14, M16, M18) and pitch (e.g., P1.0, P1.5)
• Compare with listed kit sizes: single-ended and double-ended options
• Use left-hand puller only if flywheel threads are reverse-threaded
• If unsure, remove cover and visually verify thread direction before applying force

What are the build quality and storage features?

Each puller is made from hardened steel and finished with a black oxide coating to resist rust and wear from torque. The set arrives in a blow-molded hard case that keeps tools organized, prevents damage in transport, and makes it easy to carry to the garage or track. That durable case also helps you keep fast access to commonly used sizes.

• Hardened steel construction for strength under extraction loads
• Black oxide finish reduces corrosion and glare
• Custom-molded blow case keeps all ten pieces secure and sorted
• Compact case fits toolboxes or shelf storage

Who is this kit for? The DAYUAN flywheel puller set is aimed at DIY mechanics, professional technicians, and enthusiasts who work on small engines and need a broad range of puller sizes in one compact package. If you service motorcycles, scooters, ATVs, or dirt bikes and want to remove flywheels or rotors safely and efficiently—without hunting for individual pullers—this set reduces downtime and prevents thread damage. Always verify thread size and direction before use and follow vehicle-specific service procedures for safe removal.
