Bolex 18-5 Repair Question

[Dino Everett]

I have a Bolex 18-5 that was dropped and is exhibiting a weird issue in that it plays fine but when you rewind the shutter is scraping. It looks like when it got dropped that maybe the worm gears moved on the shaft because now there is a bunch of play on the front inching knob. My thought was to get in there and unscrew the allen screws on the worm gears to slide them back into place so that when you hit rewind it won't shift backwards, BUT... to get in there I need to take off those 2 x outer gears and the plate covering .everything. My question is whether anyone has done this and knows definitely whether or not those 2 x gears are held in with allen screws or pins? I have tried a bunch of allen wrenches and they all seem to just spin,
making me wonder if they are pins, but before I start banging away, I want to be certain.

If you search on the internet, there is a series of posts with pictures that shows the entire disassembly of an 18-5 by individual needing to overhaul his unit.

THanks Thomas that answers it , it is a pin!

So FWIW the culprit here was the little black spacer in the first image with the single red pointer. It was slid too far over to the left. There are 2 x small screws that hold it in place that needed to be removed for readjustment. I actually over stripped the machine as I could have accessed it simply by removing the 2 gears (each with a pin). Instead I also removed that whole black plate which was held on with 6 screws (2 x small ones and 4 larger ones with nuts). The 4 red arrows in the second picture point out where the 4 larger screws with matching nuts go, and I will confess putting those back on was the most difficult part of the whole process in that there is a cut out in the black plate that they fit into and getting your fingers to hold that in place while you turn the screw back into them gets quite fiddly.
