As some of you may be aware i recently bought a very clean 810DLUX eumig which was bought as spares/repair. If im honest, i thought it was going to be the speed problem, advertised as one owner from new, it appears that the seller was a company, possibly the owner had given up on the hobby. Clearly, when i got it the claw pin had been snapped off. There was no way that the long term owner had done this so as i bought it for the Suprogon 1:2 lens, so as i i have nothing to lose, i thought i would have a go at changing the entire claw pin and arm assembly.
I am fortunate enough to have been able to purchase a new arm with the pin already in, as well as two spare pins with the brass shoulder.
This is such a frustrating problem and, in my view, silly design, (along with those rubber discs) in an other wise decent quality and compact solid projector. Thanks to Maurice Leaky i have also purchased the service repair book, (with the full parts listing as well). For once this has come as a proper A4 book with nice plastic cover rather than the usual PDF file so i am pleased with this, thank you Maurice.
One of the frustrating things for me attempting this is that Eumig had a tool for simply replacing the claw pin in situ. Unfortunately, this tool doesn't appear to be available anywhere so it looks like i am going to have to do this the long way so i guess it will be a good experience for me as I've never taken a Eumig apart in any way or form other than to change the bulb or gauge. This is rare anyway as in my family it's only my Brother who had had these machines, i'm an Elmo user but now have the 820 sonomatic and this 810DLUX if i can get it running again. Taking projectors apart is the easy bit, getting it back together and making it run properly without damaging films is another.
Within the images you can also see how the camera picks up quite a lot of dirt in the std 8 film path at the front so this will also be a clean up as i go job.
So here we go, from what i can see i need to remove the claw assembly to be able to do this, i cannot see any way of doing this with everything in place.
Step one,
Back cover off, lens out, gate and pressure plate out. Following the service book to the best of my ability, i have disconnected all the leads on the transformer and released the two retaining screws and removed the transformer. Next was to remove part of the front reel arm mechanism. THIS is as far as i have got today as i need to get myself some decent quality micro circlip pliers so i dont damage anything on the next stage. I will continue this on this same thread as soon as i am able to continue.
The following images are where i am at with the first two images showing the new part i am hoping to get fitted. In the meantime any advice or feedback would be welcomed.
The images also include that illusive Eumig tool for being able to change the claw pin without having to take the machine apart. What a pain, someone must have one somewhere .
