Motor mounting nuts need to be done up really tight to avoid the motor coming loose & dropping down causing damage. This special socket takes a 1/2” bar so you can get some real torque into it.
This tool is for the outer lock nut that goes over the main motor nut. Also a great tool for removal & installation of outboard threaded bottom bracket systems.
Suitable for BBS01B. BBSO2B & BBSO3B 1000w
ALSO THE BEST TOOL FOR INSTALLING CYC BOTTOM BRACKETS
