FX Crown Valve Seat Removal

[Honoo]

Hi guys,



Any idea how to remove the valve seat on the fx crown? I may have pushed it in while attempting to remove it stupidly by trying to widged a pice of plastic in it.

Any idea if I can push it from the hammer side?

What is the tool Ernest is using here to remove it? If it is the only way tho, don't want to wait until I buy a tool.

I've never done it on a Crown, but the action looks very similar to a Boss

In that case, yes you could remove the valve seat from the back side of the action after removing the hammer.

You will need a long and thin rod or other pusher, preferably made of a non-marring material (plastic, or metal with a little piece of silicone tubing over the end). Once again, if like the Boss, the back side of the valve seat should just slightly impinge into the hole the valve itself would stick through - giving you just a little lip to catch and push it forward.

This won't take much force at all - the valve seat is held into its hole in the block just by the interference fit of the (lubricated) o-ring around its exterior. If force seems to be needed, you are doing something wrong!

You can make a removal tool with a cheap pair of hemosts’s from HarborFreight. Ernest had a video out there that he shows the tool he uses.

This is the one I made it works great.

I’d also recommend making or buying an installation tool. It can take a little finesse to make sure your valve is fully seated. 
I picked one up from 910 airgun tuning.

So to close the topic, I wasn't able to get that tool quick enough and the valve seat cannot be pushed from the hammer side as the opening at the hammer side is smaller than the seat ID.



What worked for me finally is to lodge my 5.5 pellet probe in it and pull it out. I imagine that got it scratched a bit but I am replacing it anyways.



Thanks for the help all.

For the install, I just used the tip of a pen to drop it in the right direction and center, and a small Allen key to push it in a little from different sides then I just used the other side of the pen to seat it.
