Hi All,
I've got a brand new 34 that I've put about 250 shots through and it makes this squeak/honk noise when I cock it. If I had to guess I'd say it sounds like a dry seal dragging on the inside of the cylinder but I thought I'd see what y'all had to say about it. It seems like it ought to be well lubed as its brand new but I've read on this forum that Dianas are often under-lubed when they are shipped so perhaps it just needs some oil? I have some RWS chamber lube, should I apply that through the transfer port or do you think it needs it underneath to the spring slot?
I would not use the chamber lube in the transfer port.Your rifle does sound as if it could use some lube though.If it were mine I would take it apart and lube with moly behind the seal and tar on the spring.If you are not comfortable with that.(it can be dangerous the spring is under a preload)take the rifle out of the stock and put a couple of drops of the chamber lube in the cocking slot where the spring is located.That should help some.

Yep sounds familiar! All new Dianas I've seen come dry from the factory..
That ánd the fact that the cocking arm 'rides'the spring ánd the fact that the cocking arm is hollow, really makes you hear noises upon cocking..A synthetic stock even worsens this.
Solution: relube, install insulator.
Bruce,I just wanted to add my experence with chamber lube.After reading the owners manual for my brand new Mod.48 I got the RWS lube and per the book added two drops into the transfer port after a couple of tins of pellets.The first shot sounded like a 22 Mag. going off, the second was almost as loud then the rifle would not cock.Called the repair center tech. said "send it back, probable broken spring,don't know why RWS keeps that in the manual it costs them in the long run."
Anyway after three weeks I had my rifle back and all was well.I still have that bottle of chamber lube after five + years never used another drop.
The front running solution is to take it apart and apply Maccari tar and moly. The spring lube and chamber lube, but as has been mentioned; you risk dieseling. The chances of it happening are less in the 34 as it is lower powered/lower compression, but still a possibility. I have not experienced dieseling with the chamber lube in my 46's, but definitely in the 460....
When you remove the stock and fiddle with the cockingarm where it rides the action, you'll hear the squeeking sound. (but not too loud cause you do it manually, without force). I 1st thought it was the seal being dry, causing that squeeking sound, but it really it the cocking arm that rides the spring+being dry+being hollow.
What I meant to say, but forgot in my original post is that all the RWS guns seem to be coming with no discernable lube so regardless of sounds or not, probably dry. Most likely re the sounds is metal on metal (like cocking arm on piston). As seal is self lubricating...
The best way is, as already been said, to take the gun apart.
But, if don't want to do it, you can always use a thin silica oil as a chamber lub (I use it on my Beeman gs950 without problems).
You can buy it in a shop/store of remote-control cars. Ask them for the thinnest one.
