Hello again everyone!

Now I've moved on from the Swedish and
Norwegian standard bikes of the 70s into the
most recent of bike technology, namely the
mountain-bike or "MTB"!

I read on the cassette that you should pull it
40 nm. There is even an arrow pointing the way.
It is the well-known way, but OK.

I know there is a tool for this - torque
wrench, right?

I don't have one, but I do have the everyday
half-inch ratchet, and the special socket with
all the teeth (?) -


I use a regular wrench, note the length, calculate the required pull
force at the end and then I use a suitcase scales that my sister gave
me. A digital one with a hook where you normally lift a suitcase with to
see if it is still under the required 50lbs. Under $10.


of 40 nm, I know only this is a lot and the
reason I know this is every time I remove it, it
is stuck like, very firmly!


It is a lot. But I thought you Vikings are all supermen with lots of
muscle, exclaiming a loud "uff da" and off the cassette comes :-)


When I pull, I hear a crash sound three or
four times. This seems to be normal.

I asked the local guru who did bikes since the
80s. He also claimed he was a master after only
two years. Anyway he suggested it was sand!
But I'm not that stupid I don't make the parts
rudimentary clean before I operate them. So it
is not sand. Besides the sound is much to big
to be sand.

Anyway what do you guys make of all this?


On my Shimano cassettes the end piece that tightens it up has teeth
inside so it will make a loud ratchet sound at the end. I guess that was
done so it won't come loose during a ride. If the outer sprocket would
ever slip off and turn free while pedaling hard you could have a major
crash. So it better not come off.
