Thank you
Would that be 7mm bushes?
Also seen these hardened nylon tappet plates, you reckon they’d be the go?
After cleaning up the gears they don’t sit nice and flat, so wondering if that’s a sign the bushes are buggered?
Could also be the old spring on the tappet plate as its pulling on the tappet and twisting things a bit from the tension on it. Might try and find another tappet spring for it as well but will definitely look into the bushes, cheers
Dunno, matey… some nylon’s tougher than other types, but I just don’t see how you harden a piece of plastic. 
Not really a high wear item so any nylon tappet plate that suits a Gen 8 should be fine. 
Just a tip… might be handy for anyone like me who digs weird-arse build.
Running a Gen 8 in an F2000 bullpup means having to use a Gen 10 t piece so the opposite to Gen 8 offset in the t piece lines up with the mag feed tube.
Bottom line, if any of your projects require a Gen 8 box with a Gen 10 t piece be aware that to get a half decent seal you will need to use a Vector nozzle for the extra length and a few coils off the tappet return spring to tighten it all up.
Not imagining there are too many F2000s out there, but could be handy info for someone sometime. 
Will it work on any butt or just butt stocks as my missus needs abit of firming in that department.
Hope she doesn’t know my password or things may get a bit tricky when she gets home.
Nah sorry mate just butt stocks unfortunately
Dammit
Should’ve taken the tappet return spring in with me to match the size and orientation 
Tappet plate seems to fit good tho
Most expensive piece of plastic I ever bought tho
It’s easy to shorten your own tappet springs by cutting off a couple of coils and reshaping a loop into the end with some small needle nosed pliers, or making your own from a spring with similar weight and diameter.
Yeah I might grab a spring kit from Bunnings and find a more appropriate sized one and tweak it from there with the old plier method.
Looks like a gen8 style spring or the thicker spring type. If the loops orient the wrong way cut and fold to suit. Worst case you get a tighter spring.
The silver one is the original spring, the black ones a brand new gen 8… silver one still feels nice and springy but it also feels a little corroded’ish…
even buying a spring kit for Bunnings will require the twist technique. But yeah cheers
Yeah, just cut it back a few coils… pretty easy with small sidecutters.
Like Rok said if you can get the end coils to align right it’s better. But don’t stress if they’re not like the original… the spring will rotate to secure the end on the post, and once the box is together that post is screw secured anyway… It ain’t going anywhere.
Just had to do just that to shorten a tappet return spring on my tactical tuna Gen 8 box. Easy peasey. 
Nah I need a bigger spring, the black ones the replacement I bought but it’s too small. But yeah I’ll just buy a bigger spring and twist it to fit on
My bad… 
Thought it was the other way around.
Wanted to do video review of lehui tavor x95 and upgrade the spring along to way. Got pretty bad footages because I decided to keep window blinds open, but I think I can do something about it.
But for spring upgrade…
Didn’t expect it to be this proprietary.
But there’s another thing that I gonna do as well.
You get the idea
The bf mk14 fun continues…
That ain’t gonna work
How it was originally
VS the new tappet plate and spring
The new tappet plate and spring just doesn’t look to me like it will work, spring is too long and the placement of the spring mounts is way off. Even with a shorter spring it doesn’t look to me like it will function properly
Too much space to the crown gear in my opinion and the tappet plate can’t release far enough to allow the nozzle far enough forward to cycle properly and send the gel
Looks like I’m stuck with the original tappet plate unless I can find a more suitable tappet plate…
The hunt begins
Edit: My apologies to everyone suggesting shortening the spring, you were right, I F’d up. Although I’m not sure a shorter spring will do the job. Might do. Will have to try and see I guess
It’s the sun glare that’s done it.
I would be closing the blinds and finding a way to mount a light somewhere above pointing down at the bench
Or only take the pictures/videos at night
Or have a brighter light shining on the work area can work too.
Gearbox regreased and back together with original tappet plate and spring
Battery in and test fire… 
…
Nothing 
Motor goes to do it’s thing but nothing happens, all you get is a click, click and the motor “jumps” but it just refuses to cycle so it’s not rotating the gears, not pulling the piston back, not doing its job it’s just seized
Fkn thing
Couple of things to check :
Assemble it with the gears in and the box open… motor and spring out. Wind the gears by hand and make sure everything has free movement. The only resistance you should feel should be any slight friction you get from the o ring in the cylinder.
Wind if through a full cycle and check it’s the sector’s releasing correctly at the end of the stroke.
Then assemble the box without the motor and spring and check for free movement by cranking the crown gear through the hole your pinion goes through. If it’s okay, then it’s not a tight gear issue. Check that your piston has free movement too and isn’t binding on your box shell.
Reassemble full but try it again with a much lighter spring too and see what happens. From memory there’s an M100 or an M110 in that.
I’d be looking hard at that motor. Spinning up in a free state’s no guarantee it’ll spin up under load.
Might be your motor… it may spin up out of the box but not have enough grunt
I tried winding it by hand without spring in whilst holding things in place as much as possible and it did feel a little crunchy/grindy despite fresh grease. Hard to know if I got the shimming right but not sure that’s the issue
Forgot to drop the spring size tho, have to see if I have a lighter spring somewhere, think I have an m95 somewhere, otherwise I’ll probably have to try one of the older springs I’ve got floating around that were taken out of something else I upgraded the spring in
With no gears connected to the motor it seems to work with the battery connected pulling the trigger switch
Will have to try another day as I’m about to get ready to work a shift in the truck tonight, but I’ll see how I go
Thanks for the tips
