method for tightening machined / lightweight flywheel nut

[Düb Lüv]

i know ducati has a holding tool for tightening the flywheel nut for a stock flywheel. what about one that's machined down and doesn't have the 2 holding holes for the factory tool. i have an idea on making a tool, but thought i would ask first. wedging a penny between the gears doesn't sound like a good method to me.

i have a factory tool that goes over the 8 screw heads that holds the inner ring in.  it's always worked nicely.

Perhaps one of these?

Id like to see a picture of that. I thought about using my old rotor and welding a long handle on it.

Didn't think about the chain wrench idea. I'll have to see if my chain is long enough.

I did not have a factory tool, so I mde my own:



Not the most elegant, but it woks great.
The big holes go over the heads of the Allen screws, the 2 smaller use the allen head screws to hold the tool securely in place.
I also have a long, detachable handle that will block on the footpeg. Not that it brings me many favours, but the tool has had some popularity locally

put the tranny in 6th and find the biggest chunk of wood. I used 3 shovel handles wrapped in towels.

If all 3 had blades on them, I hope you took a pic.

Here's excalibur




Made use of an extra rotor laying around. Worked like a dream with minimal effort. Thanks for the ideas

[Speeddog]

That should do it.

Put a steel rod through the eye of a  conrod and lower it onto some wood   then tighten up the fly wheel nut

Just a reminder:

flywheel nut   270N/m with Loctite 128455, this as per Ducati Official repair manual[due to not having available said Loctite, I used green Loctite]

I used the double jam nuts so it's only 140ft lbs. lathered some red loctite on there.

I don't like the idea of putting stress on other engine components to tighten a higher torque fastener.

Loctite 128455 is also known as Loctite 648.

Needs to be 270Nm . . .170Nm+red loctite came off many times. now, 140Nm+red loctite+2 jam nuts . . .
