weihrauch hw 100 fac unknown spring

Hi All!

I took it apart hw 100 fac 22.cal,mod 2021 50 joule.
Somwhere in a middle of taking the C1 and valve out of the block I've noticed a small but hard spring on the table
It is 10 x 4 mm according to the calipers and 0.66mm wire thickness

I have no idea out of which part did it came out and I can not find it on exploded view that I've found on the net
I have FAC version so maybe I'm looking on a wrong exploded view

It is not from the intake valve, there is a small and weak spring inside and a ball bearing

I'm thankfull for any help and info you have!

Picture attached if could be of any help

Regards, Peter

From one of the exploded views of one you cant determine it?


As in start over and and index / elimination

That 2608 detent ball spring guess looks like good one.

Well it's simple to check and determine whether it is or not. With the mag out, press down on the little ball that is in the well. If the ball doesn't have pressure on it pushing back up then the spring is mi

No, It's not that spring that's why I dont understand where it belongs.

It goes behind the valve stem.
Had the same question, had to check with Weihrauch directly.
On the 50J version, there are 2 springs behind the valve.

All the springs i looked at this is the near excat likeness of your picture


Atleast they dont disclaim " spring shown may not be excat as pictured "'.. lol
Thanks,the problem is solved.
