The sprag clutch is free spinning when I try to start the engine...... starter motor turns Ok, nothing happens apart from noise. I opened the gearbox and found the sprag clutch is not catching when it should all the time.....sometimes it does, sometimes not. I want to remove it to see if it can be repaired, and if not, replaced.
The bolt holding on the gears has an allen key head.
A couple of questions on the removal
Is the bolt conventionally threaded? (... you turn it anticlockwise to remove)
How do I stop the engine turning over as I try to remove the bolt?

and the final question..if needed... They are pretty expensive items new. Is there anyplace I could buy one secondhand?

I want to be honest here. If you are going to do anything except change plugs and simple maintenance, you need to go take the 2 day "engine maintenance course." There are special tools used to tear down the engine. I am never going to tear down the engine but the course shows you how and shows you the "why" of every component. The cost is $500 and is worth every penny. Don't let cost, cost you your life. Good luck.

Its also a good idea to study the IPC and the Maintenance Manual. Those will provide some clues.
( see www.rotax-owner.com/en/support-topmenu/engine-manuals )

And we have a video that looks at 582 gearbox work.

Manuals are nice but it is better to have someone show you where to put the pin to hold the crank in place. This poor guy is flying blind trying to tear into the gear box without training. Thanks for chipping in with information. It is nice to know you guys are listening.

:D I totally agree, those iRMT training courses are worth their weight in gold.
