The Cone Tightener consists of 3 parts: locking collar, threaded ring and lock nut. To tighten the cones to the bore, place the threaded ring which has the lock nut and locking collar, on each side of the cones. Tighten the locking collars in place. Using the supplied spanner wrench, tighten the lock nut onto the cone which in turn tightens the cones into the bores.
