Hi,
the fine threads on the action and the two caps are very delicate. If these are damaged, rather than try to fix with other parts, its more economical to get another gun that has a known good action (even if the seal is shot), strip it, re blue it (if necessary) and when correctly assembled will last many many years.
When buying any Giss-actioned gun like the Mod 6, make sure that it cocks and fires recoilessly at least once before buying. That way you can be reasonably sure the internals are good. Scratched knurling on the side caps and end-cap are another thing that can indicate previous heavy handed intervention.
If buying spares unseen, get the seller to send you hi resolution images of the threads on both the caps and action threads. The teeth on the idler gears and the piston racks should be sharp, even and with no chips or missing teeth. E-gun can be a good source for these parts or whole guns for parts.
Good luck with the restoration.
When assembling I always check that gears can drop into place centrally between the two racks without any force required and the side pinions can be easily screwed in place with fingers only initially. This indicates that everything is aligned properly. If any force is required it means that something is out of correct alignment.

Exactly, its a fingers only job when assembling. I always do up the gear caps without the gears at first to see if there are any stiff spots (there should not be any) on the threads.
Once this has been established and the caps can be done up all the way in effortlessly, you are all set to insert the gears and close the caps while minutely adjusting the pressure on the rear piston to align the racks with the gears with the pinion of the gear caps, till the caps screw on using fingers only.
Good advice - now all I need is the parts!

Another tip I learned when repairing our six club model 6's. Before reassembly screw on just the mainspring cap a turn, then slowly unscrew it. Mark the exact spot that it comes off with Tippex on cap and body. When reassembling align the marks, back off a tad, press together against the mainspring and rotate to engage thread. No guesswork while the biceps are struggling!
