JonMundo 6 Posted January 11, 2015 Report Share Posted January 11, 2015 Hello all. Trying to fix a sticky safety on an old boys rifle, I have encountered/caused a greater problem - the barrel doesn't lock into the trigger mech'. I've taken the entire thing apart minus the trigger assembly and the problem persists, It's almost like the pin isn't long enough to catch and it's driving me crazy! Has anyone come across a similar situation on a Weihrauch? The picture shows the parts when I just took it apart so things are a bit grim. The trigger is sluggish and regrettably I didn't even check to see if she cocked before dismantling. Cheers guys JK Quote Link to post
mattybugeye 884 Posted January 11, 2015 Report Share Posted January 11, 2015 Sounds like too much pressure load or looking at that trigger unit something stuck with gunk run a bowl of hot soapy water and scrub it up mate then dry throughly and spray with brunox spray and wipe all excess off should sort that Was it cocking before? What's if feel like when you try? As if it won't go far enough down to engage on sear? If wasn't cocking before try take any preload out if non in you may need to shorten spring Also ensure the piston sear is facing right way round sounds daft but seen that done before lol Quote Link to post
mattybugeye 884 Posted January 11, 2015 Report Share Posted January 11, 2015 Another idea check the safety moves freely and spring in the safety unit is ok and not sized solid Il keep thinking Quote Link to post
mattybugeye 884 Posted January 11, 2015 Report Share Posted January 11, 2015 Last thing maybe trigger adjusted too light so won't engage Quote Link to post

When it's assembled without the trigger in place you can see the catch pull back but whether it's far enough back I'm not sure. I wish I'd checked it before pulling it apart because there's a chance the problem was already there Quote Link to post
JonMundo 6 Posted January 11, 2015 Author Report Share Posted January 11, 2015 Another thing my mate noticed was the underleaver arm seems to be catching the spring when you cock the rifle. This didn't happen before and I wonder if it's related. I think you might be right on the trigger tho, I'll have to devote some time and space to taking that sucker apart. Quote Link to post
bobcullen79 1,495 Posted January 11, 2015 Report Share Posted January 11, 2015 Piston sear was the right way round. Also the trigger pressure screw was fully unwound so it cant be it being set too light. Quote Link to post
mattybugeye 884 Posted January 11, 2015 Report Share Posted January 11, 2015 I mean the sear on the piston not trigger carnt see it in pic Quote Link to post
barrywhite 282 Posted January 11, 2015 Report Share Posted January 11, 2015 can you load the trigger mechanism not in the gun .If i remember they can be cocked out side of the gun .could your spring be to long and have to many coils Quote Link to post

johnbaz 363 Posted January 14, 2015 Report Share Posted January 14, 2015 If you don't want to strip the Rekord unit then give it a wash in diesel, Or you could soak it in paraffin or something similar overnight as it looks like someone's greased it, It should have light machine oil for lubrication You definitely need to get rid of all the 'plasticised' grease though as it creates a condition called 'Sticktion, that's friction caused by the thick sticky grease The problem should go then.. Regarding the cocking link catching the spring, I don't know why it's suddenly just started but a way of stopping it would be to make a piston liner which is a piece of .010" shim steel, some folk have tried plastic 2 litre bottle, It's cut to size so that it makes a tube inside the piston, At the end that goes farthest in, tabs are left so that when bent inwards, the spring traps them against the bottom of the piston to stop it working it's way out, this causes a barrier between the cocking link and the spring, It also tends to damp the noise from the mainspring too and make for a smoother cocking cycle Good luck with the gun John Quote Link to post
JonMundo 6 Posted January 15, 2015 Author Report Share Posted January 15, 2015 Ok so I've had it apart again and degreased the trigger which is now a smooth operator. All back together and it still won't cock. Cock. It's almost like the catching lever isn't being pulled back far enough towards the trigger catch but surely it can only go in one way - ie at the end of the spring?! Thanks for all replies guys JK Quote Link to post
mattybugeye 884 Posted January 15, 2015 Report Share Posted January 15, 2015 Sounds like spring too long remove a couple of coils and try again mate Quote Link to post
