Hi folks!
...stumbled across this thread,
and accidentally I am right now in the process
of re-installing the SRM-belt system as part of re-assembling the engine.
I've had it for a couple of years (no idea how many km/miles) and so far no real problems.
..the generator pulley has to be put on after it's been put in place on the crankcase (too large to go through the timing cover), which means it's not the easiest nut to do up tight - for the lack of means to hold everything..
The trick (although time consuming) is to remove both timing-side covers
...install dynamo (with suitably tightened up pulley)
...then the inner and outer covers
I just did it an hour ago BTW
.. The slipping on the male taper wrecked the female in the soft ali pulley, to the point where there was no chance of any positive engagement, ever. ...
I agree: the ali pulley does seam to be made of some rather soft'ish material.
I always worry if it will stay put.
Another thing is; be very careful to line up the dynamo
so that the two pulley's are in perfect alignment.
On my engine it means that I can't use the cork-seal.
It's too thick and will move the dynamo back too far.
