Do you have the Compur shutter repair manual? It will allow you to use the same disciplined tear-down process... and lubricate in the proper places.

I have only this link. Sadly it is nowhere near as explicit or clear as the Graflex manual, nor even discusses what the lubrication substances are. I'm afraid to some extent I will have to "fly VFR" on this one. Unless a better work manual comes along.

Happy birthday!

Dang... what a lousy present. The link no longer works. Sorry.

Thanks for the thought Woulda been nice. This is a special camera. May well be the only Graflex with zero mileage on the odometer. Like a '65 Corvette bought new and put on blocks.

That is the complete Compur service manual. I have it in hard copy.
The original is printed in color, used to identify the type and location of lubricants. The online is b&w.

The repair instructions in section 6 are quite comprehensive.

These were not written for DIY hobbyists. They were intended for trained service personnel.
Also, be aware that several special tools and gauges are required.

Like most camera service manuals, they were intended for the hands of factory trained staff, and assume that the reader is familiar with some factory routines and standards. So there are quite a few omissions in there, perhaps originally intended to keep out third party repair services - which make work harder now that no original service is around any more.

I have found this link. I don't know ho similar to my shutter it is, but this is a very thorough series.

HT Finley,

nice link, handy. The factory service manuals should be available as reprints on ebay, just do some hunting to find one.
Mine is still lost in the shuffle from a major move but I do remember one thing, the manual does state DO NOT take the escapement gear train apart, replace it as a unit. It does not have gears on posts, it has multiple gears on loose pins and it will fall apart if you open it. Much easier to work it thru in solvent until it runs free.

Have fun with it.

Service shops use ultrasonic cleaners for that.

A DIY effort might use an ultrasonic jewelry cleaner, if it was rather large and powerful.
A tiny one like I've seen advertised would likely not clean out the grease in the escapement.

The most critical factor in a shutter rehab is putting new lubricants of the proper type in the proper quantity in the proper places. This can be more of a challenge than it might seem.
It does require that ALL old lubricant be removed first.

This applies to the entire shutter mechanism, not just the escapement.
