BWAHAHAHAHAHAHA!!!! Thanks Bruce Cooper. Send help to get me off the floor.
That's the wrong nut some ham fisted "mechanic" installed. I see the typical
chisel and screwdriver malformations on the spring nut. SO...... Here is a classic
example of being too cheap to buy the proper tools.
Your spring nut has the REME fix to level out the clutch spring. The holes should be
2BA if done in a REME shop.
I have sets of WW tools and for that center nut I just use a 5/16 WW socket.
No big deal. I never grind down a socket as it ruins them. I think there is plenty
of room there for a regular socket.
I did make the castelated tool for the clutch spring nut, and will be doing so again
as soon as my trans continental move is over.
Check the technical section for my book chapter on a clutch rebuild. There are detailed
steps on removal and rebuild. Critics are RAVING about it.
Your comment on the tapped holes in the clutch spring nut is incorrect, the army specified 3BA (not 2BA). I did this mod to my M20 35 years ago and recall having problems finding 3BA screws as it is a relatively odd size. The mod worked well too.
