Tuning Fx wildcat hammer replacement

[ladwict]

Does anyone know how to remove the hammer ( not the hammer weight !) from a FX wildcat MK3. When I take the powerwheel off, the spring and hammer weight fall out easy but without the hammer itself in my case. Is this a matter of shaking it a bit better out or do I have to remove other screws/pins….?

thanks a lot for your help



by the way I am looking for a wildcat Mk3 hammer from hardened steel . (Approx 50 rc instead of the 20 rc the factory hammer is.)

If someone can sell me / make me one I would be super happy.

Hi Ladwict, 

If you need any extra help please give our technician department/customer service an e-mail or phone call. In the mean time here is a video of Ernest Masterclass of the FX Wildcat MkIII disassembly and you will find the Reassembly on our channel also. Hope this helps. 

Regards,

gotta just love the master class

Well, in Ernest his video he already took off “all pins and needles” from the main block before he started to take out the hammer parts. So I cannot judge from this if I can also remove the hammer without dismanteling the block first and just by taking off the power wheel can take out the hammer as well . Anyone who knows maybe ?

Pretty sure you need to remove the 3 trigger pins/trigger. Then the hammer should drop out.

Thanks. Makes sense !

Anyone ever experienced problems with the steel of a fx hammer being too soft ? It was suggested somewhere in this forum that fx uses too soft steel for their hammers (20 rc reality vs approx.50 rc wanted)

Not sure of the significance in such a low inertia application as an airgun. Is there real data to support the need?

ladwict, informative post. Thank you.

Would ik make sense to harden a fx hammer to 50 RC ?

Great thread.

 

[ladwict]

I bought a new hammer and had it tested 22RC it was. Now I will see if hardening to 45RC will make a difference . In case you are interested I keep you posted .

 

[ladwict]

I believe FX already understood the need for changing hammer material as in the newest Impact there will be a Tungsten hammer according to the latest marketing movie 

 

[ladwict]

Or probably only the hammerweight from Tungsten ?!

I had feedback today from the company that was supposed to harden my hammer . The FX hammer was examined by an expert and he siad that the hammer is hard chromed as it is. Tested from my 2022 bought Wildcat M3 hammer . 

This means that if you test it with a Rockwell test it Will show low RC as noticed ( mine was approx 22rc ) in this thread as the pin point Used doing the test will penetrate through the Chrome layer and not test the outer hard Chrome layer but was is below the. Hrome . The Chrome layer could wel be up to 70 rc. In any case at least 50rc. Iif this has been an improvement made or not I am quite sure but the problem mentioned in a 2019 thread in this forum due to “soft hammer” damage is not valid anymore.

Hard chrome is a surface treatment for lower friction and wear resistance and does not effect the materials core hardness or deformability. In this case likely to lessen friction and improve durability of the hammer in its bore. A hammer made from a higher modulus and higher yield strength material, such as a hardened tool (tungsten) steel, will transfer more impact energy to the valve stem because it will deform less and therefore compress the valve spring further.

Good input. Thanks!
