When you have securely clamped the crank onto the axle by tightening and torquing the crank bolts, a specific crank puller tool is then needed to safely extract the crank arm from the axle.
How is this done when the bottom bracket axle has no fitting conical surfaces, such as on e-bikes? In such a case (= threaded bottom bracket) you need some extra help, as the position of the crank is determined solely by screw connections and the standard removal method can no longer be applied.
We have the solution: the new Cyclus crank puller, with a longer stroke extractor (more than 20mm)! The new Cyclus crank puller enables you to remove both older type and newer deeper cranks quickly, safely and professionally.
To make the best use of CYCLUS TOOLS new crank puller, the following components are essential:
crank internal thread M24x1
bottom bracket connection thread M12x1
Special note: with the help of the CYCLUS TOOLS milling cutter (art. 720235) you can first ream out defective crank threads (M22x1); and then cut a new M24x1 thread by using the CYCLUS TOOLS tap (and die: art. 720245). At the end of the job, you won't just dismantle the crank, but will even repair it as well. Your customer will greatly appreciate this service!
Note: make sure you have got the Cyclus Tools fitting guides! Once you cut a new screw thread, you can use the fitting pullers from Cyclus Tools and thus pull off the crank as usual.
