p.s. the time and bulb levers are sticking.
Joe-keep at it, you'll get it. Download the manual that shutterfinger posted the link for (I did-thank you!). There are a couple of diagrams showing all of all the spring locations that will be incredibly helpful.
WOW - that's a very interesting document. Thanks.

Example #1- blade opening spring broke. I was able to make one from brass that worked but was not as strong as the original which is copper.
Example #2- arrived with the pin in the timing gear next to the cable release socket broken off. It was run until it stopped. I made and installed a new pin.
both shutters came back with speeds at the edge of tolerance for some speeds and within tolerance on the other speeds except for 1/200 and 1/400 speeds.
Back to doing a CLA on a #2 Graphex.
Wollensak Raptars were re badged Optar for Graflex Corp. cameras.
Thanks for persisting through my short sightedness - I admit I was skimming the replies I the first time saw it and missed that the link was the whole point of your post.

Nothing resembling my specific symptoms appears in the troubleshooting list, is there anything specific you think may be needed here or just a general CLA? I should mention that the issue cocking the shutter when the speed is set between 1/10 and 1 sec. seems to have worked itself out with some use. The chief issue that remains is simply that shutter durations are about double what is marked which I understand is pretty common with these shutters.
I'm also curious about all the references to M and X synchronization but this shutter has no selector as this shutter has no such selector and the terminals are just marked X. Is this a special version, or maybe M synchro was phased out at some point?

The Rapax came in 3 versions
No flash sync,
Full flash sync M-F-X as covered by the manual. M, red or black and F are types of flash bulbs; X is electronic flash.
X sync only.
The X sync only has a simpler flash sync parts and is fairly easy to service as some components are the same as the full sync shutter.
The speeds being slow says the shutter is due a full disassembly, clean, lube, reassembly. It will stop and die.

They are not as difficult as they seem. Keep each sections parts separate from the others for easier identification.
A trace of oil is all that is needed where oil is called for, a dab of white lithium grease or similar about the size of a straight pin head or less is all that is needed where grease is called for.
Use a degreaser that leaves no residue to clean the metal parts. I use CRC Quickdry electrical contact cleaner. Isopropyl Alcohol works well also.

Tip: use a digital P&S in macro mode and take pictures as you remove parts as this makes reassembly easier.
Rub extra fine powdered graphite into the shutter blades and aperture blades and their pivots without bending them or leaving fibers behind.
To expand on shutterfinger's good advice...When I disassemble shutters, I have one of those plastic "bead boxes"-basically a flat rectangular plastic box that's divided up into compartments. Each component of the shutter I remove, along with it's associated screws and springs, goes into one compartment. When you get ready to reassemble, you just start at the last compartment and work backwards. I use naphtha, white lithium grease, and gun oil.
