Timing belt replacement

[dreja]

" One of us worked with the braker bar while the other held the camshaft sprocket in place with another wrench"

So when removing the CRANKshaft pulley bolt one held the CAMshaft with a wrench. One or both?

So the timing belt absorbed the force (the force was distributed from crankshaft to camshaft throught the timing belt)?
Helding the crankshaft instead of camshaft is perhaps not possible (no space for using 2 wrenches togheder on the pulley)?
