Also for clarity just have a look at this exploded diagram HERE
. Would you be able to point out which part the top hat is? I'm a tad confused (as always).
Once again many thanks Kieran
The "Top Hat" is numbered PSW 004/5/6 and fits (screws) into the piston side of the Spring, into the three "dead" coils on the MKl & Mkll spring.
There is a thick steel washer that is listed PSW 003 that will lift your power too, Air Arms told me that it was a "running in" spacer, and was removed if the gun went over power
The hardened steel spacers that I use as preload spacers are listed as W093 on the TX 200 Mk lll
The hardened steel spacers can be fitted at either end of the spring, I would normaly fit at least 1 at the spring guide end to aid with wear, but they will also fit inside the piston, infront of the top hat, for setting the power if you want.
I get the nylon washers from Jeff Skinner (Redfearns) - they are the same as a regular washer but made out of nylon, and these will only fit in the piston side as they wont go over the spring guide..
I believe that the V mach kits instruct fitting their preload washers infront of the spring, inside the piston too..
Hope this helps
