Brno ZKK 602 Exploded View and Parts List
      #171166 - 09/11/10 01:57 AM

Been working on this ZKK602 exploded view for a while, cleaning up the scanned image and adding a parts list from another ZKK historical source... should give a clean A4 size print.

Just thought I'd share with NitroExpress members who may own an example of the big Brno... lots more in the forthcoming ZKK Guide

Thanks TilleyMan.
Got my copy and look forward to the ZKK600 and the ZKK601 (hint,hint).

Cheers Neale.

The link to this appears to be gone. Anyone have access to an owners manual?
I have a ZKK602 in .375 H&H that only came with the standard trigger. I recently bought a single set trigger off ebay. I'm just wanting to make sure I have what I need to install it. A good number of the parts I got two of, including the trigger itself. This is what I got.

Can I buy your old standard trigger please ?.

If you are missing anything to do with the single set one,I will have it as I have four of them sitting in my draws.

Not even sure I'm going to like the single set yet. Just figured I should give it a go and see.

Hello PHMadness

Good haul of ZKK parts... the lozenge shaped part with a screwdriver end is a bolt disassembly and trigger adjustment tool.

Appears you have all the parts to install the set trigger, you will need both the lighter shim spring and the heavy spring, the light one nestles inside the heavy one and stops the trigger from rattling when unset. Long side installs uppermost.

See the following image for assembly:



Remove standard trigger and anti-rattle spring by removing Pins 1 and 3 (it should have been fitted with the light spring only)

Install the set trigger by replacing Pin 3

Install Pin 1 with both the inner and outer spring nestled together (long side uppermost)... the end of the light spring fits into a small notch at the rear of the set trigger... may need a bit of fiddling with a fine screwdriver tip to get it to click into place.

Using needle nosed vice grips (well padded with leather to prevent marring the trigger bow area) compress the end of the heavy spring until Pin 2 can be installed. The end of the heavy spring will be held under great tension by this pin... it acts as the 'sear kicker' when the set trigger is released.

The small screw in the side of the set trigger adjusts release pressure... once installed, the trigger is set by pushing forward till it clicks... release pressure is typically about 8oz but can be adjusted a little with the screw. Using the special tool, loosen the screw (anti-clockwise) to increase the set trigger release weight, tighten it (clockwise) to decrease the set trigger release weight. Of course check your rifle is unloaded before these tests

PLEASE NOTE:
If the set trigger release weight is set too light (ie it is screwed in too far) the trigger may not set at all or worse may release unexpectedly all by itself. Needless to say, this condition is extremely dangerous

Once you think you have it adjusted properly, set the trigger once more by pushing it forward, then bounce the butt a few times on a firm surface to ensure it won't release unexpectedly.

If you don't feel confident about making these set trigger adjustments, please take the rifle to a competent gunsmith.

Hope this helps...

Cheers

TM

Another newbie question: what is the barrel thread dimension on the ZKK 602? I have a spare .375 H&H barrel from my Sako TRG-S that's looking for a new host...

Sorry about that Bokmal, I had been looking for that tool and a set trigger for a couple of years myself.

Thank you so much TilleyMan, that is exactly what I needed to know. If the weather holds, the public range is open Wednesday and I'll go try it out. Too soggy for the desert this week, that's where I prefer to shoot.

The BRNO ZKK set trigger uses two of the springs in your picture.....main springer (heavier one and I see two in your picture) and set spring (lighter one). The springs are retained by both pins. The trigger reuses the existing mounting pinand its tricky to assemble. You have a complete set up. You should be aware that the trigger for the 600/601 is shorter than the 602. Measure against your existing trgger to determine what you have. If not let me know and I'll measure one of mine.

Word of advice...don't part with your single trigger...you may want to go back to it and i'ts tough to find.

I've got a few single/set triggers/take down tools and one piece factory scope bases for the ZKK if anybody is looking. You can email rgg_7@hotmail.com Ron

TilleyMan, it would be worth asking NitroX if he's willing to host the exploded diagram pdf, to give it a permanent home.

Shouldn't think there would be any problem, given the files this site already hosts.

Good idea, haven't found a free server for PDF's that will allow indefinite uploads...
