With all the parts and tools in place I would say, allow a full Saturday and just take your time. Be methodical and double check things as you go. If you get stuck just shout on here.

Good luck!!  Just remember to let the shaft lock cure (Loctite)....dont get too excited and 'try it' straight after assembly....you need to know that the flywheel has set to the crank, despite the 150NM torque needed on the hex bolt to hold it on.  No glue.....it'll all work loose.....dont forget to put it on the 6 bolts that hold the sprag ring onto the flywheel too....you dont want these coming off either!
Even though the bottle will say that it cures in 4 hours....give it 24....then you'll know.  Nothing worse than that niggling feeling 'did I do that right'?
One more thing.....write down a torque check sheet.  When you put stuff back together, torque it, tick it, check it and tick it again...thats how I do it...a bit anal, but better to be sure than not.

Good luck!

You do not use a hub puller, you need one of these.

You guys must be sick of this, but I think my sprag has gone as well. Made it to the petrol station and it just wouldn't start again. It made a spinning noise and then a horrible mechanical noise...as if it was trying to start but instead of 'catching', it was just grinding something. The rac duly came out and checked the battery, fine as I've just changed it to the higher charge one that's recommended. Then the starter solenoid, that was in a sorry state, the wires were partially melted and the connections were pants, these were cleaned up and taped, while being in a bad state it was sending the current across and still no start. He said the starter, I said I've heard about this sprag clutch issue and he looked at me like I'd just been babbling in Farsi. So...does anyone have any ideas? If it is this sprag clutch I'm willing to give it a go as well, is the general consensus a KTM part? Does anyone have any guides they could forward at all? Thanks in advance for any responses!

Guys ... I know this thread is a few months old....however I have not yey finished the job !! just started my own business so not had any time to spend on the repair.
I have stripped it down to the part where i have to take the flywheel off, however even though I bought the correct Apprillia tool I can not remove the flywheel!!!
It just stripped the threads off the tool - the tool is pretty crap, but i thought using the right tool would do it. Still it wont budge. I have been using a heat gun ...but am considering upping the heat and using a blow torch. Will this do any damage?? someone told me it could damage the shells ??
I am deperate to get a few miles done before the summer ends... and apart from hiring a van and taking it to Griffs I am a bit stuck ! And the point of me doing it was to save money !
So I need to find out exaclty what tool i need to pull the fylwheel off - or has anyone got one I can borrow ?? Griff advised me to buy the one that machine Mart do, however it dosent fit.
And - do i need to use a blow torch to add more heat..?? Cry

Blow torch is a must.....heatgun is just not man enough to do it.

You need to get the end of that shaft to at least 400 degrees C to break the shaft lock.  The loctite in there is not thread lock, its shaft lock, its bloody tough.....no wonder you stripped the threads!

Just work the blowtorch around the centre, around and around.....you'll feel like your over doing it, but your not....it'll take a good 10 minutes.......the metal may even turn blue with heat.

You'll also need a rubber mallet.
And once the heat has got into that end, put the flywheel bolt back it, but loose.

Get your mallet and tap around the flywheel till it comes off and the bolt stops it dropping off the end.

Let it cool right down....that'll take some time too.

Once the glue is broken, you could even use a normal flywheel puller, use it on the end of the bolt that is in, so when it eventually pulls off, the bolt stops it coming off the end.

I'm certain when I did mine, it took little effort to get it off after the heat.  I really throught I was going to f**k it up with all the heat I was putting in it!  But I didn't.

Just make sure you can put out any fires you might start!!!!!

When you do put it back together....use the right shaft lock and let it cure once you tighten the flywheel bolt.

Oh, I burnt my hand on my flywheel.....I thought it had cooled down...it had, but I guess 150 DegCs is still too hot!!

weve given up using pullers buddy...we went to a local fixings supplier and bought a M22 x1.5 hardened bolt that does the job admirably so far!

we use ours that frquently that we broke it again!

Can I just use a standard 22 x 1.5 bolt? do I need to machine the end or anything?
