££££Expensive afternoon...?????

crawsue · 12-07-2020, 07:06 PM

Had a spirited run out this afternoon,then ,thump, something kicked me in the arse, yup snapped chain...

...also, couldn't pull in clutch or find neutral, so fingers crossed it's not an engine seizure.....any clues...? Neutral light has been playing up,....lack of use, maybe, I'll check it tomorrow.

Mr Gazza · 12-07-2020, 08:09 PM

Oh dear! I think your title could be quite prophetic!

It sounds like the chain could have heavily whiplashed the engine cases round the clutch pushrod area? Preventing the pushrod from moving.
If so this will not be a simple repair. You need to remove the sprocket cover and clutch slave to assess the damage.

I hope I have given a very worst case scenario.... Good luck.

Luddite · 12-07-2020, 08:25 PM

Really sorry to hear that, Crawford. Glad you're ok though.

Was that the chain I gave you? Did it break at the joining link or was it one of the regular links? I can't think why it should fail on it's own as it'd done less than 500 miles when I gave it to you and had been stored lubed in the box.

Let us know what you find and hope your title isn't too prophetic.

Thanks guys, starting a stripdown later today, will update this evening after arranging an interview with my bank manager and marriage counselor.....

mickj · 13-07-2020, 08:42 AM

That's bad luck, my wife had a chain snap on her bike once but luckily it just shot out the back in a straight line so caused no damage or injury, I hope you and your bike get fixed up soon.

utopia · 13-07-2020, 11:35 AM

Fingers crossed that any damage doesn't stretch too far.
I concur with Gazza's thoughts on what you're likely to find.
On the positive side, you don't report any loss of engine oil so hopefully the crankcases are ok and the damage is limited to the clutch pushrod and slave.
I presume you didn't have a crankcase saver in there and if not, I would suggest fitting one.

crawsue · 13-07-2020, 06:35 PM

Well a couple of hours with an angle grinder, cut a chunk off the front sprocket and extracted the doubled over chain,cut had caused some surface damage to the case and squashed the hard rubber guide/ seal against the clutch push rod. Got it all freed up and found neutral and it's okay!!!!
New chain and sprockets and chain run/ guard will get it running,cbut I'll need advice on two outstanding matters, I'll need to dress the chips/ gouges on the swingarm, ay ideas on what the coating is?
And how is the chain run/ guard fixed to the swingarm....looks like some kind of rivets, s there an aftermarket copy or will I have to bother Borgo Panegale/ bank manager?
Not sure what caused the chain failure, well lubed, looks like it takes at joining link.
Anyway, look like I've dodged one.....

Luddite · 13-07-2020, 07:02 PM

Wow! I think you dodged a bullet there, Crawford. Good news.

With the chain guard, do you mean part no. 1 in this diagram? It's held on with three screws but you'll need to remove the wheel to access them. It's around £15 new (part no. 44610192A).

I'm not sure about the swinging arm finish, but I think it's a crinkle powder coat.

crawsue · 13-07-2020, 07:17 PM

Hi Ludd.... it's the long black plastic part in fig A of your schematic.....seems like a Ducati bargain.😁

Luddite · 13-07-2020, 07:23 PM

A bargain indeed! They often come up second-hand on eBay but are invariably more expensive than new.

Mr Gazza · 13-07-2020, 07:32 PM

You had a very lucky escape, I'm pleased you got away with it, I really thought the worst.

I would still clean it all down and look closely for any cracks, and then keep an eye out for oil leaks when you get going again.
Hopefully that rubber part took the blow and protected the cases.

Have a look here when you get a minute.. http://www.ukmonster.co.uk/monster/s...ad.php?t=49399

crawsue · 13-07-2020, 09:03 PM

That looks like it's worth a shot.... I've definitely dodged a big bullet this time, I'll have acgo at running a protector up....Thanks for the heads up Mr G.

crawsue · 17-07-2020, 08:38 AM

Is it safe to assume that the fixing points for the crankcase protector are the two sprocket cover mounts? Cheers for any info. C.

Mr Gazza · 17-07-2020, 08:51 AM

Yes that's right, it's the same screws.
It does make the sprocket cover sit out by the thickness of the case saver that you make, but a small price for peace of mind, should lightning strike twice.

Darkness · 17-07-2020, 09:00 AM

What front sprocket were you running? If it was the standard 15t at the front, it might be worth trying one tooth smaller as that makes a case saver easier to fit.
