Frequently Asked Questions

Q: What vehicles is this flywheel spanner wrench compatible with?

A: This Y-Type flywheel spanner wrench is designed for use on most standard scooters and mopeds. Its adjustable arm opening of 15mm–120mm means it fits a wide variety of flywheel pulley and magneto sizes commonly found on 50cc–150cc scooters and moped engines.

Q: Why is the wrench made of solid iron instead of stainless steel?

A: Solid iron offers greater tensile strength than stainless steel for high-torque applications. Stainless steel, while corrosion-resistant, can bend or flex under heavy force. For flywheel and clutch work — where significant torque is required — solid iron is the more reliable choice. Simply store it in a dry place after use to prevent rust.

Q: Does it come with the pins already attached?

A: Yes! The two detachable steel pins come pre-installed in the wrench head, so the tool is ready to use immediately upon unboxing. The pins are also removable if you need to swap them out or replace them in the future.

Q: Can this wrench be used for clutch removal on a moped?

A: Absolutely. This spanner is specifically designed to handle flywheel, clutch, magneto fixing clip, and belt disc removal/installation tasks, making it ideal for clutch work on scooters and mopeds.
