RWS (Diana) Model 45 Disassembly, Part 1

I finally got around to opening up my RWS branded Diana Model 45. It’s the second one I own and was shooting slightly slower (730fps w/ 7.9gr. CPL) than the Original branded one (800fps w/ 7.9 CPL). You can see earlier aesthetic improvements/downgrades to the rifle here.

The rifle. I really need a larger workbench.

10131102
This was an unwelcome surprise. Sheared screw on the scope mount. It was shifting anyway and needs a stop so I’ll have to mess with it.

10131100
I punched out the dowel pin that retains the rear of the action (note, if you’re reading this and you don’t have a cross pin holding the action in, you don’t have an early model 45, you have the later one that is unlike this one.)

10131103
Two phillips head screws for the front action.

10131104
The action removed and inverted to show the trigger.

10131105
The cocking linkage.

10131106
Much better than welded ears for retaining the tube.

10131107
The safety pulled out to show the little interference bar. Compare position to the picture below.

10131108
The dowel pin that retains the action in the stock passes through the trigger assembly.

10131109
Mounted in the spring compressor.

10131110
I didn’t like that the force was applied to the end of the safety but what are you going to do?

10131111
Two pins removed.

10131112
Spring tension taken up and the trigger group removed. Things can start to fall out of the trigger group at this point so be observant.

10131113
I pushed the piston up as far as I could. Note the spring and guide on the bench, forgot to take a picture of them.

10131114
I need to remove the barrel to get the cocking linkage detached from the piston.

10131115
Lock washer.

10131116
That seems like an awfully thin pivot bolt…

10131117
Ah, there’s a sleeve that’s the actual pivot.

10131118
Which is a nice design as it avoids the screw being subjected to rotational forces and becoming too loose or tight.

10131119
The end of the linkage unhooks.



More to come.
