For KE21SP owners, the Kyosho 74031-10 oneway bearing is a practical spare that restores smooth recoil operation. It is produced to fit the recoil assembly and help maintain reliable starting behaviour.
The Kyosho 74031-10 is matched to KE21SP recoil systems and is a useful item for hobbyists who value consistent starts. Its straightforward profile means most users can replace it without specialised tools.
Before fitting the Kyosho 74031-10, clean the recoil housing to remove dust and old lubricant. A small amount of light oil will assist running in and protect against early wear. Check the KE21SP manual for alignment details.
