Re: Can the stock trigger pull be reduced?
As I had previously stated in my Timney Trigger Installation Instructions article this pin is Uni-directional and must be removed using a hammer and narrow punch. It must also be put back in after the new trigger assembly has been seated in place.
When removing this steel frame pin out, you will need to punch it out from the side the Safety Selector Switch is on and tap it out to the opposite side of the crossbow frame.
After installing the new trigger assembly and cocking the hammer to the load position, you must re-install the steel hammer block pin from the side of the frame you removed it. The use the hammer and punch to re-seat the pin until it is again flush with the frame of your crossbow.
Once you complete this step, the hammer will hit the steel frame pin each time the trigger is pulled. Just make sure that when you complete the assembly process, that your trigger is in the loaded position and everything has been tightened securely.
Also, when you attempt to load your xbow the first time, make sure the string loop is being placed over top of the second string catch on the crank block. The first one is the anti-dry fire catch and this needs to be depressed by the arrows nock. If you make the mistake of dropping the string loop over the wrong catch, the hammer will fire, but the crossbow will never release the string and this will force a manual let down of the loaded bow using the hand crank and cocking release lever.
I hope this helps you in resolving the problems you were having.
