Video Tutorial
Stride 1. Removing the grit cap
The zigzag is tightened onto the spindle with a crank commodities. more often than not older-style cranks seal this commodities with a grit cap .
Earlier you get to the separate where you tin can have the crank of the spindle, you ' ll necessitate to remove the besprinkle detonator. In my case there ' s a small slot at the border of the cap of the dust cap which is pressed into set. Y'all can put in a flat-headed screwdriver and pry information technology out .
other versions of scatter caps have broad slits in the center, a hole for an allen key or two holes or a pin wrench. All of these versions are screwed into topographic signal .
original dust caps are both rare and expensive. That ' randomness considering the flimsy plastic damages hands and they tend to get lost. therefore be careful when trying to get them loosen.

Be careful not to cross-thread the fine threads in the crank. specially when the dust caps are missing the threads might be dirty, making information technology unmanageable to get the grouch puller into rate .
The threaded part of the crank puller is screwed into the crank sleeve. When in place the rotating tip presses confronting the bottom bracket spindle, pushing itself and the beatnik with information technology, aside from the spike.
If the creepo puller goes in about half an column inch, yous ' ra good to go. While holding the crank with one hand the other tin rotate the printing counterclockwise with the aid of an adjustable wrench .
