1000-5m-20 Belt Requires Sprocket shimming or swap or modification for use. We have even found that slight Shimming to Xcooter Thunder. Atx 1000 a.k.a. Raser Big Wheel a.k.a. PanthR models that have 102 tooth aluminum wheel sprockets with lip out can be shimmed behind sprocket to allow for running even 5m-20 belts. Not sure about Salorr Big Wheel model using 5m-20 yet without fipping both sprockets and maybe replacing wheel sprocket from plastic to aluminum 102 tooth sprocket from Chuweng.

1000 Belts that are 20mm Wide need Spacer/Shim for wheel sprocket to allow use of 1000-5m-20 belt.

560-5m-15 Belt For use as clutch belt when 575 clutch belt is still loose even with motor/engine adjusted all the way back. If motor mounts are weak and dry rotted, replace them first to eliminate that being the source of a belt tension and adjustment issue.

580-5M-15 Belt Some Chuweng Raser or xcooter thunder THS Big Wheel scooters used this belt from factory with 20 tooth trans sprocket to later find it became too long over time...unless your scooter has a 24 tooth trans sprocket. Reccomend superceding to 585-5m-15 belt if you are using a 24 tooth engine/trans 5m belt sprocket. The most common belt used for the left side or clutch belt with a 20 tooth engine sprocket and a 60 tooth shaft sprocket is a 575-5m-15. replacement of dry rotted twisted mis-shapen motor mounts can cause belt tension & alignment issues and incorrect length choice or misdiagnosis. your motor can be adjusted forward and backwards slightly to help with belt tension. we recommend replacing the motor mounts if the motor mounts are dry rotted or they stay twisted with the transmission belt removed.
