Flywheel ring-nut tool?
DIR By: Sigean

Hi,
Just to be prepared, I need a tool to undo the slotted ring-nut
which is part of the flywheel attachment. I have seen mention
of this in a few threads, but could anyone advise where to buy,
or offer the dimensions of a tool in case I need to make one?
Grateful for any comments,
Sigean

It's called a cold chisel . NLM advised me on this and it
slackened off easily with a few taps. I did choose the most
appropriately shaped one from my abundant selection. I had more
trouble getting the right socket. It's not a common size and I
had to order. None of my mechanic mates had one. Needs to be
thin walled or won't slot on, so none of those bare metal black
ones.

I have a tool, made by a friend. Someone's already been at my
nut with a chisel, and I added to that with a blunt one, to no
effect at all. It's seized solid. The tool is just a heavy gauge
steel pipe, with OD to match the ring, ID to slide over whatever
socket you use on the centre nut, and 4 castellations cut to fit
the lock nut. Mine has a hole for a tee-bar. You really need
something to lock the flywheel too. Tonya drilled and tapped his
for a locking bar, but I'd prefer not to take a drill to mine.
In theory, putting it in top gear, and locking the back brake on
should do it, but given the scarcity of gearbox parts,
I'll not be doing that. Maybe a strap wrench around the
circumference?

Many thanks for these comments. I guess they told me what I
have been avoiding - that I need to make my own tool! I saw a
Youtube video by a very helpful pie-smoking German chap who was
removing a Falcone flywheel and he had the correct tool in the
form of a castellated socket, and very nice it looked too, but
no advice about from where it might be purchased (such advice
might have been a mixed blessing as the video was given in
German.....). No matter, I have a lathe and an angle grinder,
and can read a steel rule, so there should be nothing I cannot
do!

If you have a lathe, it's no problem at all, and if you can wait
a wee while, I'll be happy to measure mine up (once I find
it...).
Given the difficuly I've had getting mine off, I'm considering
having a socket welded to the end, so I can take a breaker bar
to it.
I'll see if we can get some pix up of Tonya's tool and flywheel.

II got a socket made to fit the castle nut inside the kickstart.
this also fits the circular nut on the flywheel.Didnt have a
socket big enough and the nut inside was seized.

Managed to find both Tonya's tool and the spare nut and locking
ring. Here's a drawing for the tool:

You can see that the bore can be smaller, because Tonya's used a
section of welded pipe, and the weld reduces the bore by a few
mm.

Here's the other side, with the castellations:

And the whole tool:

The locking ring itself has a major thread diameter of about
49.75mm so presumably nominal 50mm and an internal diameter of
about 40mm. The recesses for the tool are 5.84mm wide x 5.2mm
deep.

Here are the tool, nut and locking ring:

The nut measures just under 29mm across the flats, so a 29mm
socket would be required. Might get away with 1 1/8" AF.

Does it look pretty similar to Tonya's tool Cloggy?

For completion, here's Tonya's solution to locking the flywheel
with 2 holes drilled and tapped, and a Y-shaped locking tool:
