FWW install

I busted the FW nut of with an impact and tried to torque the weight on by holding the rear brake.
I managed to get a good "click" at 20, 30 and about 40 ft lbs...spec is 40 or 42. Is this good? Is there any load or force applied that if I'm not at spec, something catastrophic will happen?
I'll run it a while and then check torque again.

Any tips for locking up the FW to torque it?

I just put my flywheel back on with the same electric impact wrench I took it off with.

If it loosened up it would shear the key and the bike would stop running. It would be very difficult to kick the bike over and you might think something was much more wrong than a loose flywheel.

I popped mine back on with the impact wrench too.

Most companies make a flywheel holding tool. I have a couple different ones. What make/model bike?

IF you don't mind stressing your spokes a bit you can shift to high gear then put a wood bar through the rear spokes and against the swing arm the torque away. This is how Rekluse suggests you tighten the clutch hub nut which is often around 100 ft lbs

Thanks guys. I think I'm good. I'll ride it a bit and recheck. I was just curious as to how others did the same thing.

Works for clutch and drive gears as well. Of course you have to pop off the clutch side case to get to the crank/clutch gears to use this tool, but it holds them perfectly and doesn't hurt the gears like a penny or screw driver can! Torque away. While jamming something in the wheel works, you can mess up spokes sometimes. On the trail, sure this method works well, but if you have the time, take time to not damage parts if possible.

Nice thing, it has a little magnet that holds it in place until the gears lock up on the tool.

Very cool tool. A penny works well, much better than a screwdriver, because it's soft. It'll get mangled and never be able to be used again when you're done, but in a pinch it's a good alternative.
