RGS sprag clutch

I have recently got my RGS Corsa going for the first time. After a couple of test rides the noise from the sprag indicated it needed attention which I have done. The bike has only done 12,000km and everything was in very good condition in there (including the three screws holding the plate on, I couldn't budge them). The only issue was all six springs were shorter than the replacements.

I found lots of useful info here to help me get this far.

Anyhoo....my question.

I don't have the special tool to hold the alternator flywheel, I got the centre bolt out with a rattle gun. What have people done to hold the alternator flywheel when torqueing it up or is the go just using the rattle gun again (which grates my mechanical sensitivity which is why I'm asking).

Short burst with the rattle gun, been doing it that way for the past 40 years... a drop of Loctite Blue helps keep it in place.

Careful if you have a LH thread fixing bolt (LH and RH can be found), rattle guns are often unlimited CCW. I've found many a stretched bolt there!

I use an old T-shirt and a broom handle, as a makeshift strap wrench.
Keeps it simple.
 
but Hamish you havent got an RGS, the 180's are different to the 120's, all you need to get the alternator off is a bolt, to lock it, top gear and tread on the brake usually works, other methods are available, but a tee shirt and a broom handle? get a proper strap wrench if you must you tightarsed Jockanese twit, they are only about three quid! in fact I might even buy you one, when is your bi-anual birthday?

I was taught never to lock one end of a (pressed together) crankshaft while twisting the other end, Clem.
Advice that's worked well for the past sixty years.

To be fair, the factory did issue a factory C-spanner to hold the flywheel while tightening the bolt. While the Mk II/120 models are fairly straightforward with the moderate torques that are called for the bolts, the 180 with ridiculous 150Nm is a very different proposition. After quite a few brazed knuckles and squashed fingers I simply took the easy way out with the rattle gun... never looked back.
