Found this on Cisco's Micra files...

Is this right - first you push it in and then turn clockwise so it's held in place?
Then it looks something like this (bad pic cause my PS won't work :glare

Then I must put it in and bolt it on (6-8Nm)?
I don't have this (red thingy) to retain it

But to be honest I don't even need it cause I can put it in without it. So far everything ok?
How does the spring release then so it tensions the chain? Last time I drove only 2km and tightened it by hand (think well over 6-8Nm) and when I took it apart it was stil held in place like here - http://www.shrani.si/f/2O/5R/4nlYCUo1/271411.jpg :suspect:
Don't want to make the same mistake again....
