I had no idea of how to fit my new spring and wasted much time messing about trying to fit the it.
I will give my experience and hopefully easier way that I used in the end, hopefully helping others with this fiddely task.
Buy your new spring from Paul on here- the Scott one doesn't fit tightly on the shaft, it may work if fitted but slipped off during fitting for me.
Remove the two bolts nearest the shaft holding on the gearbox plate.
Fit the new spring the correct way round on the shaft so you compress it pushing clockwise.
With the housing over the spring holding it-
With a finger or screw driver compress the spring turning the housing in order to get the tab lobe end to start to enter the housing.
Hold it in using the housing, turning it gently back to line up the top Allen bolt hole and tighten just finger tight to stop the spring jumping out.
Fit the two other bolts finger tight
now with two flat blade screwdrivers work the spring into the housing pushing gently only until it enters the housing
make sure its in right round by pushing the housing.
My gear box leaks slightly into the spring housing which I think helps lube the spring so I pulled the housing out a bit and ran a bead of silicon round the edge of the housing to hold the oil in.
I have not used the bike much yet but it seems to work correctly.
I hope this helps others as it is a pain of a job and to start with I was convinced the spring was too big!
