Christmas gathering damage

[shaneMember]

Ripped the clutch cover off today to find exactly the same thing I did on Saturday. One of the friction plates had jumped out of the cage and spun around a bit and the drum nut was off.

The Vor owners manual recommends something like 60Nm of torque on the drum nut(must try to find my torque wrench thingo), but then it goes on to mention Lambrusco, bruschetta and then something about lunchtime….it’s a poor Italian to English translation but I’m becoming more suspicious that I have a “Friday bike”.

There photos attached below (hopefully), I’m about to go back out apply some loctite and torque the nut back on. If anyone with The Knowledge has any other tips I’d appreciate them.

Closeup of the clutch plates. See the top one? She’s come out of the basket and is sitting up on top.

The position the nut was found in

Oh Dear!

I have tensions wrenches etc here at home should you need one, can you stake the nut to stop it coming undone? Let me know if I can help, am not far away

At least it’s not catastrophic mate TB idea’s is pretty good. Putting a small pin would help hold it in place.

The shaft that the nut attaches to has slots cut into it, looks like a castellated nut. The nut itself appears to have never been staked and looking at it looks like there’s no way a split pin or similar could be attached.

TB do you have a 1/2 to 3/8 drive adaptor? Found me torque wrench!!!

[GregMember]

Dont know so much about the adapter of the top of my head, but have a 3/8 drive tension wrench that will do the job mate. I am at home as well mate.
Not talking about a split pin, am talking about staking it as in after its together, using a centre punch to dent the shaft / or thread to prevent the nut unwinding, or staking the nut to distort it some it cant unwind easy, requires effort to do it, (much like talking to Moto) lol

You wouldn’t believe it. My torque wrench is also 3/8 but the 30mm socket I need to use is 1/2′!!!!

I know what you meant by staking the nut but I’m concerned that if I do that I might bend the shaft (you’ll know what I mean when you see it)

I’m thinking I’ll loctite it and tension it up, see how it goes then?

[GregMember]

Will drop a 1/2 drive tension wrench around tomorrow after I go into work for awhile, after what time suits you?

Superglue it. Use epoxy like araldite or something, that will hold it.

Funny comment too TB, especially when most of the talking is always done by you

[shaneMember]

Ta for the offer TB but I’m back at work tomorrow, unless you want to pop down into the dungeon and see the conditions they have me working in!!!:laugh:

I went out and had a think about it over a couple of bundy 101’s and here’s what I’ve come up with:

Since the shaft has slots in it and the washer behind the nut has tangs that fit into the slots in the shaft, I’m going to loctite the lot after tensioning the nut to VFT and then bend the washer up one of the sides of the nut and then araldite the bits to buggery which will stop it spinning. (Maybe the Italians forgot this step during assembly?)

Test ride to work in the morning, if it re-occurs I’ll use the workshop tools or I’ll get one of the trucks to back over it:woohoo:

Good luck Shane, I hope you don’t have to pull it down again. The upside is that you will be geting very good at it now :p

[shaneMember]

Indeed!

I’ve had that clutch apart about 10 times in the past two days!!! But I’ve finally had a win thanks to the clarity afforded me by my friends at the Bundaberg Distillery!

That bloody washer behind the nut? It has tangs on the inside for a reason! The shaft is slotted for exactly the same reason! The washer ‘looked’ damaged from the nut letting go but on closer inspection, damage was from the factory bending the washer over. Trouble was, back in 2003 when the bike was rebuilt, the lads didn’t return the washer to it’s original position and the thing sat there for 5 years :ohmy: Kudos to the Vor factory!

I banged my head against the wall in frustration when I realised all I needed was to bend that puppy over and…viola!

Thing’s good to go pending a test ride on the black stuff tomorrow:woohoo:

And for a change it cost me nothing but a missed ride and some time.

Well it’s good news to hear a fix no costing any money. Cluthes can be expenseive problem areas too!

No need to hold the bike together with superglue after all!
