Decided to have another go at this one this afternoon,
Someone from the other channel mentioned that this particular circlip is only used on the Eumig projector's meaning that the correct pliers will not be available anywhere.
While these clips are Eumig designed and do the job, one has to ask why they didn't just do what everyone else does and design there shafts with a groove to take a normal common e clip which would make things so much easier.
Unfortunatly i have ruined two of the clips so i will see if i can obtain a few, otherwise, i'll have to think of something else. I'll worry about that when i come to put it back together.
Today, i managed to remove the whole claw unit. I had to remove two gears as shown,
from the other side i needed to pull out the front sprocket shaft and the film guide and upper loop former. Back inside, there was a single screw holding two flat metal springs, (item 712-5020), The Claw unit itself is held in by three screws, one cylindrical and two centering screws. These were secured by the grey colour paint from factory but were actually very easy to loosen and remove. Removal of the claw unit is now a case of manoeuvring it out gently and carefully.

here's the thing, this is a simple job made difficult by, (in my view) poor design, unnecessarily awkward clips for what should be simple removal of a few gears, poor design of the having to get that white dot at the top making the breaking of the claw pin too easy. This job overall only requires the pin replacement which, if Eumig made getting hold of that tool easy, could be done in place through the lens barrel as per the service book.

Image 4 shows a single washer from behind the gear, the service shows states remove the two washers, the book also shows two but this projector only had one, i did check the back of the gear to make sure it wasn't stuck to it. Image 5 shows the front sprocket and threading guide and loop former removed.
The last image shows the claw unit out.



Part three will be the simple, (i hope) replacement of the claw arm and pin assembly, somehow, i think this could be very fiddly but i will see how it goes and hope these images help others. Without the correct clip removal tool it is a pain as i dont think normal circlip pliers will work, i have a few pointers now and have bought a few sets but so far all are too big. I removed these using two small screwdrivers and some choice words to help get them off.

What surprise's me more about this project Tom, is the bloody clips are hard enough to get off, but when you do get them off they break !!!!!!. I can't help wondering that eumig did not
want the end user to actually fix it themselves, so making it very difficult to repair with out specialised equipment, and only supplied to the "official " repairer. So 40 years later or more no one's around now, and certainly no one with the specialist tool to refit the broken claw, necessity the mother of invention has had come into its own here, well done Tom for having the balls to attempt this, just for that poxy claw, so when you have fixed this you can get yourself a GS because after this little escapade the elmo probably won't frighten you any more than this has .................

Exactly Paul, however, john white who does repairs these machines does have the tool but as you would expect, it isnt something he can give out,(as i wouldnt if i had one due to how scarse it is).
The easiest thing for me to have done would have been to send it to him, but i did get it to play with.
Its just the frustration levels go up when you find out that the clips are unique to Eumig and makes a relativly easy job very difficult.
