Thanks for the replies.

Luckily one of the the guys from the metal-shop at my company has offered to make one up, so I'll see if it works this weekend if my breaker bar turns up...

ooooooo :)


Let's face it, you wouldn't go to a nurse to get good advice on a problem with a Falco - you'd choose an Engineer or a mechanic...

Well I looked into the problem a bit further today, and it's not the sprag clutch.

Anyone want to hazard a guess as to the cause?

Don't tell me; some numpty has wired up your starter motor to run backwards????? no wait.......that numpty was me :smt013

Go on put us out of our misery...............after my problem apparently "fixed itself" I'm keen to hear what other "whirring" noises can be attributed to

Is the spring around the sprag tight. A slack bugger will cause the rollers to skip and not grip

Well, I removed the alternator cover with the intention of tightening the sprag clutch spring, and was met with the sight below:

Image

Image

All three of the bolts that mount the sprag to the back of the flywheel were rolling around inside the rotor, with bits of magnet and copper wire. The flywheel is a bit mangled on the inside, but I hope it's save-able. The stator on the other hand, is fucked:

Image

Image

So I pulled the flywheel off, and found that the bolts hadn't come loose, they'd all sheared off!

Image

At least the sprag seems to be in good condition!

So I now need a replacement stator, or to get the existing unit re-wound. Anyone got one kicking around, or know a place that could repair it for a suitable sum?

It would also be handy to know which models the stator is common across, I would guess the <04 RSV is a pretty safe bet, how about the later models?

How the hell has that happened? :smt017

First time I've ever seen that happen. It looks a right mess!

Best of luck with the repair, sorry I can't be of any assistance but keep us in the loop as to the solution (and its cost)

The ends of the sheared bolts can be spun out of the sprag easily, so I guess loctite wasn't used when it was last (first?) put together.

If the bolts came loose they'd be taking the turning force rather than contact between the flywheel and sprag, possibly resulting in the mess above.

Options so far either seem to be getting the stator re-wound for about £130 or an aftermarket replacement from eBay costing £80 that needs the connector soldering on.
