Size of cylinder head nuts please
 

What size spanner for cylinder head nuts on a 900ss 91 please. Going to try and get rid of the oil leak this weekend.
Anyone have the Ducati special tool to borrow ?
Have a top man helping so not all bad.
Thanks Kev

15mm. Can't help with the tool i'm afraid, but if you weld a socket mid way down a 15mm ring spanner, you can calculate the torque required at the torque wrench.

Thankyou Mr Nelly
Its obviously not true what Dibble says about you :o
Please bear that in mind when you calculate his invoice.
Cheers Kev

15mm ring spanner will do the job-- but you may have to grind the ring a tad thinner to get onto the nut--i used an old spanner and welded an old socket with half inch drive to take the torque wrench along the spanner shaft to make the special tool

must learn to type faster- bit like my riding really:lol:

haha i just discovered the need for said tool this weekend.

Its surprising how much you have to grind the spanner down to get it to fit.

The need to buy myself a welder seems to grows with each bike i own...

Think its a trip down the car shop for a cheap Draper ring spanner to grind down rather than the Snap On :eureka:

Thanks for your help
Kev

Got to drop the engine out first though, oh what joy !

I think I used a combination ring / open ended spanner and just happened to have a piece of box section the right size for the ring-end and getting my torque wrench on as well.

Do you think any of you could post a picture up of the spanner?
I'm gonna have a bash at making one up.

Thanks in advance

The spanner is shown in the Haynes manual - its like a big 'C' shape.

Just had a look at the www.duc.nu site and the workshop manual on there - and the special tool is simply shown as a double ended ring spanner with a square hole tube built into the middle to allow a torque wrench to be fitted straight in.
