Okay, I finally removed the old cranks by using a nifty tool called CWP-5.
Now I have a question about putting on the new cranks: What are the best
methods of doing it?
Do I add my hand pressure to push down the crank over the tapered square
bolt, then tighten down with a bolt nut? Or should I use a rubber mallet to
hit the crank so it can go down further, then tighten down with a bolt nut?
dont use bicycle sites as a referance for unicycle crank installation,if you tighten just the nut you will strip the threads.
use grease so the arm goes on farther and so you can get it off someday.
use your rubber mallet then tighten the bolt.then go ride for awile and hammer away on the crank again and tighten the nut again.check your nuts regularly (crank nuts that is ) they do loosen a bit with time.
Oh, I like Sofa’s little instruction page. Only thing I would add for the crank install is to make sure you don’t get any grease where the retaining nut will sit or on the threads for the retaining nut. Grease there will keep the Loctite from getting a good bond which can allow the retaining nut to loosen on its own.
Grease the tapers
Press (or pound) the crank on
Make sure no grease gets on the threads for the retaining nut
Put Loctite on the retaining nut
Tighten the retaining nut
Along with all the other great advice, I’d have to add that there are indeed moving parts. I would consider the action of the crank moving along the surface of the taper as it’s installed a moving part.
As well as moving parts, you want to put grease where two metal surfaces come in contact. This prevents them from seizing together (like the seat tube in the frame) and in the csaee of cranks, it also lets the cranks slide up the spindle easier
