On I go…
With the barrel removed, I noticed that one of the washers looked suspiciously like a hardware store washer. Rusty too.
The other washer is a characteristic Diana stamped shim washer.
Underneath the wrong washer was another correct shim washer. So I probably have to make a replacement for the rusty one.
The piston was sleeved.
The sleeve and a washer that the end of the spring bears against.
With the sleeve removed the cocking shoe fell into the piston. Not sure how it goes back together but I bet I’ll figure it out. 
The rod in the piston is both spring guide and safety actuator.
I presume this square hole is what gets caught by the trigger assembly.
The piston seal seemed to be plastic at first.
But a gentle scrape with my fingernail shows it’s just dirty and compressed leather.
I cleaned it off with some alcohol.
I have no idea how to get the seal off. Any ideas? In a more sensible gun the steel bit there in the center would be a screw…
Sure looks like a pinned and peened post holding that seal on - maybe a rivet?
ReplyDeleteI'm guessin you're going to be doing some drilling, some screw fabrication and some tapping.
Well it look like a blind cross pin holds the seal on. The seal looks pretty good so I'm probably just going to clean it up and use it as is.
ReplyDeleteI have never owned a 45, but I do remember conversations in the past about the relative difficulty in changing the seal when the time came. If you get the desire to change to a synthetic seal, here is a related post http://www.network54.com/Forum/184474/thread/1241594961/last-1241684111/early+style+RWS+45+piston+seal+question
