Nato Hitch workings

Evening all

does anyone have a exploded diagram of the workings of the nato hitch plz?

mine has never span through 360 it was thought that the previous owner had painted it and just well gunked it up but ive got the thing in a vice now and took off the front 2 plates in the vain effort to try and clean away the paint and make it move.
no real signs of paint on the front but the back part of the block seems to be welded?? would this stop the thing revolving?

not overly important that it does move i just wanted to if i could make it work but as i say if its welded theres no way i can get it too now

cheers keith

Range Rover Blues:
If it's the spinny type, then the back plate has a circular cut-out machined into it, then a spigot is welded in through the back, perhaps the welding you can see. 
The spigot goes inside the back of the jaw to support the towing weight.
The front 2 plates then cover the circular foot of the jaw casting which is machined to fit the circular cut-out in the housing.  The front plates only really support the towing force, not the noseweight. 
There is a grease nipple for thew spinning part on the driver's side.  The spigot should have a flat machined onto ti to prevent grease forcing the jaw off the spigot when greaded, otherwise you could dissasemble the hitch with grease pressure.

hobbit:
Can you post a pic of the one you have?

landroverkeith:
ill try and get a pic posted later on after work then

but yes it does seem to be the spinning type as is has the twin jaws that lock it it in the upright position as to speak and as rrb says once ive taken the plates from the front of the jaws are indeed part of the round swivel bit behind the plates. its the welding on the back thats threw me

ill get a pic up asap guys ty :)

Lucy1978:
When I got mine it wouldn't spin either.  I bolted it to something solid and put a long pole through the jaw and lent on it till it started moving worked it till it was free and greased it up.  This process may have involved beating it with the no. 1 adjusting tool a bit too, but that sort of goes without saying. ;)
